My friend brought one of these over recently. You're spot on with the "fets" and the silicone. The board looks good, I looked at the silicone around the MOSFETS suspiciously myself, to hear you mention them makes me feel real good about it. Thanks again for your service. I will do my part to keep Plasma TV's out of the landfill.

Thank You for making this video. Just fixed my blown plasma by replacing those two FETs!! You've helped save another plasma from the landfill!

Ordered your kit and as a novice solderer was able to fix my TV, thanks!

Another Norcal masterpiece. Thanks. This helped me sort out a BN44-00446A out of the slimline smart model 51D8000. 2 blown FETs and same main fuse blown. after 3 failed attempts including doing some caps around them. I'm always on the lookout for cracks but missed these completely. After seeing this and using some jeweller loupes found the same cracks you did. replaced thos FETs and fuse again along with repairing the bad joints and has not failed after 4 hours. Was lasting about 50mins and must have heated up enough for one of those joints to fail and short out. Cheers

YOU ARE A TRUE T.V ENGINEER YOU EXPLAIN ALL VERY WELL FOR ALL OF AS TO UNDERSTAND THANK YOU, I HAVE FIXED MANY T.VS BY USEING YOUR TEACHING.

AS always, you present a very useful tip and demonstration of how to service a PCB. I've watched many of your videos and have learned some good tips I'll use regularly. WD

Ideally, you should have replaced the drive IC as well, as sometimes (even with the gate drive circuitry testing OK, the drive waveform can be corrupt, and the transistors may blow again after couple of hours even if TV set works ok. You can use the scope to measure the waveform, and check temperature of the heatsink with the laser thermometer to find out if the FETs are not running two warm aftr the repair. PFC circuts usually do NOT run very warm. Good Video!!! regards from Holywood Rd TV repairs, Befast.

hello would you please reply me? Hello please Mr.Norcal i have exact issue shorted QP804 easy to read part# 6R190C6 but shorted diode DP804 ...etc my problem is QP806 is shorted open resistor 47,20 ohm...etc , instead of asking you for QP806; QP805 PART #? CAN YOU tell me where to get this BN44-00445c schematic? if canot then WOULD YOU PLEASE GIVE ME PART # FOR QP806, QP805 And my last is QS802 that drive the opto isolator . please replay me if you can to save me from yelling wife for opened tv every where in the house :) ! have a great day sir

I ended up repairing my PSU card after having to replace it 3 separate times. Found a bad diode (more like degraded), but noticed my PSU was still restarting the TV on and off (original discrepancy). I had already replaced some caps that may have gone bad but had no visible signs with a higher voltage tolerance. But what I found out was that the Vs reading was showing 220V (supposed to be between 214.5v and 223.5v). When I adjusted the pot for that voltage, the buzzing from the power distribution card (not the PSU) got softer and the TV stopped restarting. Tested for a full day and no restarts. Not sure if I fixed the issue or just extended the life of the transistors temporarily. What I almost ended up replacing was the relay. I felt like it was opening/closing on its own after every 3 min as if it couldn't handle the current/voltage levels. Do you think I fixed the issue? What exactly is Vs and Va?

Hi ,, My plasma samsung 43'' i v connected the powersupply board seperately , n after switch. On , all the voltages come on and immediately drop down to few volts,,,,, plz advice .... It's a ps43e490b3r samsung..... I'm from Goa . 🙏

I have the same power board same problem, do you take mail in orders and if so how much to fix? Thanks

You mentioned that QP805 and QP806 sometimes fail as well. Mine has those components blown (along with RP807 & RP808) but I can't identify the transistors/diodes by the limited numbers on them. Do you have a replacement number for them and perhaps a source?

I had a problem with my set, no picture but sound. checked your video and found one loose pin on a mosfet. re-soldered it and so far so good, the set has been running for 15 minutes now usually it would run for 2-3 minutes while the mosfer heats up then the computer would shut the power supply. Do you think i should still change the mosfet? there must be a reason why this solder was loose? I've read my VA and VS and they are good.

So what board would I replace if the Samsung 60" Plasma TV won't "Start" when hot? "Starting" is when you press the on button, see a little flash on the screen followed by the blue Samsung logo and then your signal. Not "Starting" is when you press the on button and nothing happens but five seconds later the power light flashes on and off. Let the set cool down, disconnect-reconnect power and the set "Starts" as normal. Any idea what board has gone?

Really hard to say, I would start with a cold set and then warm up each board one at a time with a heat gun or a hair dryer until you can determine which board is causing the problem. It may take several days to find the bad board.

Can these two MOS FETs be tested in circuit. My fuse is blown and the same two test shorted D to S in the circuit on very similar BN44- 00619A. Thanks for showing how to test the gate inputs.

i have this exact board. i did notice. two soldier terminals cracked where you replied get them fixed asap. my samsung plasma 59 inch. picture goes off after a few minutes, still has sound. i pulled and checked the y boards and the IC chips are ok.

Thank you sir. Great video. I learned a lot. My bn44-508a is rumming but the problem is D5 output is 5.12 volts, it should be 3 volts only.

It has this exact same power board (including version). What testing did you do to determine the power board was the culprit? I have done repairs on computer monitors by replacing caps, etc, but haven't found any damage to our board, no bulging caps, etc.

Hi, Thank you for this video. I have one of this pcb which has an issue. there is a short circuit between 5.3V and GND. fets were also damage and move at the import was blow too. I was wondering if you have the Sch of the boards, of if you know what might cause this issue?.

What is the part number of the green capacitor?

Hello, Awesome video! I have the same board and DP804/06/08 are burnt what can I replace it with. I would appreciate your reply : ) Thanks in advance.

Great video thanks for posting. I have a 2010 Samsung PN60550E Plasma I am trying to save. I replaced a few of the capacitors on the power supply. When I got the TV (free on Craig's List) the tv had no picture, no sound and the red light on the front of the TV was not lit. I now have a red light on the front after replacing a couple of capacitors, but still no picture or sound. I also noted that there is a small LED light just above the input for the power cord and it does not light up. I am wondering if the LED light on the power supply does not light up if that might be an indication of something. Thoughts?

I have a power supply board that fails to start only when the YSUS Buffers are plugged into the YSUS board. Replaced both the YSUS and the buffers with no luck. Could it be the power supply fails only under load? I am tempted to replace the power supply board as well...

I've got a Samsung plasma, pn50c590, and I get a burning electronic smell and sizzle/crackling noise when I power it on. No picture just the Samsung sound. Any help would be appreciated. Thanks

I bought a similar kit for the BN44-00515A from ShopJimmy.com through Ebay. Would you happen to have a diagram or picture of the back side of that board showing which direction the 2 small IC's ICP801 and US801 face? I had them marked with a maker on the board but my solder flux and alcohol erased my markings when removing the old IC's and I don't want to install the new ones backwards. Actually enough of my red mark on the small 8 pin IC survived to clearly show it was installed opposite the markings on the board. (The little arrows in the artwork on the end pins which I would have assumed indicate the pin 1 side and that's how the 3rd IC not replaced in the kit is placed, but this really makes me 2nd guess weather the original IC was placed correctly and I have no clue which way ICP801 faces. I want to get them right the 1st time and not have all my hard work and new parts blow up in my face. You have a picture of the back side of the BN44-00515A board on the Shop Jimmy website (out of stock) but it isn't quite clear enough to see the IC polarity. Do you have a more clear picture or diagram you could email me? keshenatech1@gmail.com Thanks

Good Info - Can you please also explain how to check the Power supply output pins to first identify that Power supply is actually working. I have a samsung PS51D8000 power supply (BN44-00446A) and I want to check if it is working properly or not. My Samsung TV has died couple of days ago and there is no standby light even coming ON. I have multi-meter and for my learning purposes, I want to start checking the power supply myself. I have checked the fuses and it is working fine. Continuity shows that there is no broken connection inside the fuse of Power supply & the main plug. Appreciate if you can guide me some basic checks which will help me to learn it, thanks

I have a tv the fuse looks to be functional. Should I replace the entire power supply board since the tv has a soft ticking sound when it tries to power on?

Absolutely great. Quite enjoyed watching this whole video. Totally agree with u regarding better picture quality with the plasma but unfortunately the components used and some of the designs are quite cheap and nasty. The dry soldered joins and ringed dry joins DO seem to be getting less common. Mostly the cheap n nasty components from manufacture popping. Currently working on a 42" Plasma Bush, BPDP42HD3. No picture but sound fault. ybuffer ok. Ysus board supplys xsus board. Its a bit of a head scratcher :(

An isolated 1Mohm resistor @10:50 doesn't dissapate anything if it isn't connected to ground. It must connect to ground to drain the charge somewhere and the resistor will save your life It's not magic. It will limit the current that would otherwise kill you if you accidentally touch something hot, but that's the only protection it gives you as you will still get zapped. It does not by itself magically dissipate or absorb static electricity either.

Hi, great video, thank you! Have you ever seen the MOV/Varistor blow (crack in half) by the relay? I wonder what could have caused this? TV was fine, powered up and running a few minutes then we heard a ‘Pop’ and fuse blew on the mains plug (both internal fuses fine!) - the varistor is the only part that is damaged. Replacing plug fuse and powering up blows it again instantly... board variant is BN44-00619A. Just seems a bizarre fault to me!

You tube is awesome, never knew all this free education existed, videos are everywhere on PFC, its what I paid for yrs ago. If you want to learn electronics, get yourself a scope, sig gen, power supply, DVOM, bread board kit, clip wires, and components, there are free circuits all over the web to build, measure and test. you can buy am radio kits and such. Do that and I guarantee you will learn. In school we built simple circuits consisting of 2 to 5 components max, you think oh that's simple? come back and tell me. Spice simulation is also good, I had a program like that at one time. Learn DC and ohms law first, then go to AC then digital and semiconductors. Maximum math we used was algebra and trig, two yr degree. You MUST do the math as part of it. Its all safe, you use low voltage low amperage circuits, the sig gen makes your AC sine wave so no mains involved, have fun, burn stuff up sometimes, its how you learn.

I’m repairing a similar board BN44-00515A in the same area. Already replaced a 10A fuse, QP804, RP807, RP808 and RP812 which were fried. LP804 is open cct but I can’t figure out its value. It’s under 10uH as far as I can tell with my cheap LCR meter assuming it’s the same as one in the adjacent cct. Where can I find a cct diagram or parts list for this or any similar model as they all seem about the same design.

I'm not sure how to properly test the MOSFETs with my multimeter, but I removed the silicone and desoldered both QP804 and QP802.

PFC (power factor correction) changes the phase of voltage to current relationship. If the current draw is in phase with the voltage then the power factor is a perfect "1" This circuit makes it from about .6-.65 power factor to about .8-.85 (or better) power factor. Just makes it more efficient in other words.

The rivets allow more solder to be "wicked" between the lead and the rivet.

Static electric precautions is the last thing to worry about when working to these beasts.If the flat ribbon cable coming from controller for example is not connected to the side boards then board will burn transistors rapidly.Intermittent failures which are difficult to locate also occur.In general the plasma tv's are the worst type of television ever made and are the hardest for service operations even for professionals with many years of experience.

Why oh why use a single sided boards for a power supply. Heavy components and hot components cause a lot of joint stress =failure!

The wire in the soldering station base that grounds the tip to the earth ground of the line cord is cut and a one meg-ohm resistor installed instead. (as in joining the two cut ends together with the resistor) This gives the tip the anti-static protection and will prevent an apocalyptic short if you accidentally touch a live area on a chassis with your iron.

Cheap Chinese made components insted Of Japanese made components just to save a buck on each TV. I know thats a stretch at gussing whats going on. But it probably has some facts to it. I wont watch anything but a plasma TV and my oldest unit is over 18 years old working without a hitch, but my 1080p unit i belive uses this power supply Now I understand some of the basic electronics behind this repair but you did some serious board leval repairs. People dont do this anymore they just want to swap boards. I can take a guess and belive its my power supply or crack it open and test componets to find the problem and fix it. This was a 60" budget TV nothing big deal about it. Now becuse I can buy new sets at dealer cost should I bite the bullet and go with qled? They use a lot less power and my sets been turned on almost constantly its whole life, last time I turned it off it was hard to get it to turn back on over a year ago. If it comes on it works. This leads me to belive its bad solider joints. As most of these boards run down an assembly line then over a solder bath then washed off with water. Im going to bet every component was placed by robots. Most of these are not hand soldered anymore and this power supply works on that whole skew of models from 3d to normal on the plasma line mines a 60" i belive the 47-60 all used the same power supply. Other components would have been differently made. Like the x and y boards. Im just gussing. Plasma were supposed to last 35 40 years. Not like the old CRT or tube type sets. And they gave a lot better picture. I remember changing tube in the 1960s tvs but that stuff would be impossible to find today. Unless you have a Marshel Amp. I belive the tube cost 110 to 140 bucks each now. My what solid state has done for us. Don't touch the flyback! You won't live to talk about it. I take it the output voltage is dc volts or was it ac volts and low amperage? Not sure i want to probe a plugged in board. Its still 120 volts ac. The power supply drops and bumps the voltages for differnt circuits. Depending on the needs.
