Huge thanks for such detailed, simple and to the point problem solving skills.

Another great instructional video with intimately detailed commentary, thanks for taking the trouble, hope you get a buzz from doing them for us. Ray H. ( from the U.K. )

Thanks for the video and tips. Revived my family's dead led tv, Sony KD-55XD7004. Saved me ordering another main board, just used a hot air gun, circling underneath the chip area for about 10min until i could feel the heat through to the chip's 'white' heat spreader. Reminded me of working with bga components some 8+ years back. You know your stuff well. Thanks from Finland 🇫🇮

Awesome video with deep explanation of what could go wrong and troubleshooting steps, thank you

Nice find! I'm learning a lot watching you!

I had and LG 46 and used your method but using a heat gun for 20 sec about 2" from the chip and it works now!!!. Thanks for taking the time to publish your video.

Thank you so much for taking the trouble to tell us all how you fixed this problem, I enjoyed every bit of this video. I especially liked how you broke it all down to basics and explained in full detail your trouble shooting..........I have just subscribed and I am looking forward to more of your clips. Ray H. From the U.K.

You are a very good teacher, thank you.

Thanks for the tip. It worked for my TV, which had similar symptoms. Instead of halogen bulb I used incandescent light of rating 100W for 1hr about 3cm above the board. TV turned on successfully. There were also few white lines on the display, they also got fixed. Happy... :) Thanks for the tip.

Thanks man. I always enjoy watching your videos as a Technician. Very informative. ..

Thank you! You saved me from buying a new tv. I was all set after removing the back and tightening the screws on the power supply.

Wow, that's all it took. I used my soldering air gun on the chips at 180°F for like a minute and the red standby light came back on. I reassembled and my TV turned on! Friggin amazing. 🙌

Brilliant. I had no red led light and no power except for pins 2 and 3 showing 3.35V, used a 50w halogen bulb on the big chip "engine" raised about an inch from the board for about an hour. Let it cool for 15 mins then tried it. Working perfect. Thanks a lot from London

GREAT information, I am from the old school of not using too much heat on transistors or any solid state devices, I find this amazing that that heat lamp re flowing solder did not destroy those chips. But again like I said I am from the old school, vacuum tubes and some transistor work back in the 60's. Thanks for the great educational video, enjoy your channel.

your a genius.. had same problem with my lg 60'' model 60 LB5900 UV. would not turn on, would unplug many times, then it might come on. it got cold in my game room and problem got worse. heated the XD engine square modules with hair dryer for several minutes.. works like a charm.. thanks!! Todd

very clear and very detailed troubleshooting and components checking and repair.Thank you for sharing this kind of video...

Thank you so much for the tip! I used a hair dryer for just a minute or so and pressed the chips with my finger. Worked like a charm!

Excellent video for solving TV problem Detailed and to the point Very well, thanks for sharing your problem solving skills

Thanks - your video helped me diagnose my LG TV (Followed your tip regarding ground screws - it fired right up after this).

Thanks Brotha, you saved me a lot of time and money. I used a heat gun on a Sony 60 inch, used a heat gun, and it worked, been using it for 3 months now. Again Thanks.

How long time did you used the heat gun on the main board?

I just cover the surrounding area with tin foil. The chip is isolated. put a nickel or quarter on top of the chip for bit of weight and a very small piece of solder on the tin foil next to the chip. Turn on a hair dryer on low or a heat gun on low and heat up until the solder on the foil melts, then heat for 15 sec more. Works every time.

You just saved my buying a new TV. Used a heat gun, worked beautifully. Thank you!

Thank you! This fixed my tv! Let's hope it keeps working.

Really surprised to hear it wasn't the power supply. I reflowed the solder on my Insignia power supply board when I discovered poor solder joints and it works perfectly now. I'll keep your video in mind if one of my LG tv's fail. Thanks!

TLDR: very helpful vid. 60" lg plasma w/red standby led no display&sound, ruled out basics/pwr cable/power board (no obv damages/traces/loose connections/bulging or leaky caps, volts/grounds good) hadn't considered reflow (specifically cpu/other chips) will attempt that too. Thank you for additional possibilities. Recently obtained an older lg 60" plasma, TV's are pretty cheap these days and most are not worth the time trying to fix but I miss the picture quality of the old plasmas over most of the newer TV's and enjoy learning different repair techniques especially since I'm an electrician by trade so your video was very informative and to the point on your thinking process and has given me some additional areas of attack.

Good video I love adding extra components to those boards running different hardware

Very helpful thanks. A Lg tv I picked up tonight wasn't turning on so I put the gas heater on and placed the back of the tv 2 feet from the heater 25 minutes and a slight distortion to the back plastic I plugged it in and it turned on . Nice cheap Tv.

Quality fix well presented 👍👍👍

I rebaked at 385 degrees for 10 minutes and 390 for 5 minutes the solder was nice and shinny this bake tv is off and running again thanks again friend

Great video ! I tried it and my tv works . Thank you ! Thank you!!!

Excellent video my good sir, I picked up a LG model - 55LS4600-UA at the recyclers today, I opened it up and looked at the capacitors on the power board none were bulged. The issue I was having was the RED Stand By Light would light up. But if you tried turning the TV on, nothing would happen. I used a Wagner Heat Gun for about a minute on the IC101 and IC1201, then after letting it cool, POW! the TV fired up! I'm glad I got it for free though, since i didn't notice the small crack in the screen till i got it to light up. Wish i could fix the screen now, but i guess it would cost too much. Just glad i learned something today :)

Just wanted to say thanks! My LG 42lk550 is 5 years old and I couldn't find any parts for it, like a mother board. I ended up using my heat gun on level 4 on the dial for about 6 minutes and shazam! It didn't have a picture or sound and now it works. Never knew this trick until I watched your video. Thanks again.

Neat, trick. My went out in a power surge. Plus I found one some one set next to the dumpster the following day. I just bought my 40" a few months ago. I will try this trick on it.

really great teacher :) BR from Poland

Wow what a simple fix to save a TV! Amazing!

We actually got this TV from our local waste site. The TV looked like it was clean, it was missing a remote control though. We turned it on and it worked great as a rarely used bedroom TV. I got a remote off Amazon. Then our 65" Samsung back light bar (just one, we think) has gone out. So we brought the LG out. It was solid for 2 days. Then it had all the problems you described. So glad we found you!!! We're going to try this to see if it works. I hope you have a video showing how to replace the backlight bar on my Samsung.

Game changer, awesome thanks for the tip brother!!

Thanks. The heat trick saved me my money. :)

Well done my friend and every interesting info.Keep it up :)

Sir thank you for this tutorial video the Idea in it will add up to my little knowledge in fixing led television ,have a nice day...

Wow. You're very smart!! I wish I could speak that intelligently! Especially after covid I'm lucky to complete a sentence without getting twitterpated. Thanks so much for a detailed video! You should be a teacher or do some electrical instruction videos online! People would totally pay to watch these and learn what you know!

Great video! Thank you.

Nice job and super video sir

Very well done! Can the board be heated from the back with a heat gun and to what temperature? I watched many of the other's showing a bad power supply board and know that is not the 100% given. Thanks again for your thorough step by step instructional video.

Thank you so much :-) my tv (LG 42lx6500) was also dead. So i looked inside it. Everything seemed perfect. so i looked at the screws and drill them a little bit - aaaaaaaand the tv is working again. It was a Ground-Problem with the screws ... Damn^^ thank u for showing/saying that :-*

Thank you! 2019 sharp 43” Red standby light won’t turn on. Swapped out power supply no luck. Heat gun for a minute each main board chip did then trick. Hope it lasts

Hi I did the same with a friends PS3, i use liquid flux and used a heat gun to heat the chips up and it worked. dont give a shit if it's not a full time fix it was a favour and it still works today over 12 months, at the end of the day it's working and not in the skip. Thanks again for a fantastic vid dude. Simon

Great video! I used the same repair on my LG TV (different model, but same concept). I used a regular 100W incandescent bulb in a floor lamp with a metal reflector. I put the lamp directly over the chip in question and left it there for an hour. The TV immediately worked when powered back on. I'm guessing having my TV mounted above the fireplace for 5 years was a bad idea.....

Hello could you send me a link of this bulb, i'm not english i don't understand what it is. Thanks a lot !

I heard about those Onkyo receiver BGA problems... I bought a new TX-NR818 and put little RAM Heat sinks on all the chips on the HDMI board. And have fans on top of the unit pulling heat out and cool air in from the bottom of the unit. Hopefully will prevent this failure.

Thanks for the insight. I bought a used TV and after bringing it home, it wouldn't turn on. Power board has the standby voltage being transmitted to main board. So I assumed Main Board must have kicked it. I am going to try your method and see if it helps.

Great Video! I'm try to fix my electric pool vacuum control unit. The wind knocked it over and it won't power up, same a your TV, has a power board and a control board. I guess a hard jolt when the unit is on is not healthy for these boards? Won't power up at all, I did check the ceramic fuse for continuity.

A great fix

used an oven for laptop for heating up the graphic chip. It works almost every time :-) i removed the cpu and ram wires etc. oven was heatet up to 200 celcius and the mainbord was in the oven for 20 minutes. while it was in the oven i clean the fan inside and removed the old themal paste ( was hard as an rock anyway ) themal paste i used was arctic mx4 works every time 👍

thank you very practical and helpful video#trandungha

I actually used a cheap chingy Heat station on a BGA chip a few years back now and the sucker is still going, the trick is getting the temperature just right..

great master

Genius!

Hey I literally used a hair dryer, and the red light came back ! Then when I put the HDMI cable and chose HDMI in the menu it became frozen with lines everywhere. Do you think the power was not enough ? Do you think it could work better with a 300W heat gut ? Because I cannot buy more expansive for now. Thanks !
