You're welcome! I learned a lot of stuff on KZread myself, so sometimes I like to return a favor and share my experience also.

Just wanted to let you know, the LM 171W02 (TL)(B2) is the normal stock screen for the iMac. The UniMac V4 is used to replace this screen with a more common type of screen such as LP171WU1 (TL)(A2). That is the reason that LM 171W02 (TL)(B2) is not in the compatibility list. Sorry for the confusion. - Adam RealMacMods

Thanks! I just replaced mine with your help. Couldn't have done it without you!

hey Serg. great video and saved me a job of replacing all capacitors on logic board. Very clear, very precise. Thanks very much and keep up the good work. cheers

Not the news I was hoping to hear. But thanks for posting.

Thanks for making this video Serg. Very helpful.

Hello once again SergSpace! I once conversed with you before. I used your other video for replacing my Logicboard on my IMac Intel 17" 2.0 GHz computer, and your informative video was absolutely a great contributor to letting me do so! But, I initially just replaced the thermal compound on CPU, Graphics Card, and Nosebridge chip(not sure what that one is actually called) on original Logicboard other than placing on the brand new, unused one. It actually worked fine for 3 days. Then, the light flickers on the screen began to appear for a few hours like it had did before on the display and the same thing happened...a pixelated screen reappeared. So I went ahead and put the brand new one I had purchased still in original packaging and all, and even still had the brand new smell to it. I took computer apart again, and was still getting the same results. A pixelated display. I figured since my com had been sitting unplugged and unused for just under a year, that was the only reason it worked for those few days, 'cause it had been rested. I made a video, and wanted to see if you can give me your thoughts on if you might happen to think it might be my screen which needs to be replaced. And please believe me when I say, "I will not hold you at any fault if your information does not pan out for me!" You seem like a man with great integrity, whose heart is set on helping others with their IMac problems in which Apple seems to keep the info to them selves! And even just for your help with the other video of the Motherboard, if we lived in the same town, I would have been honored to buy you beer or 2, or a meal on me, for helping me save hundreds of dollars on not taking it to a technician. If you can please respond back to me as soon as you can, it would be much appreciated! Thank you very much sir! Link to my IMac problem - IMac Intel 17": kzread.info/dash/bejne/dJaGqMuzdLLZXZc.html

+El Steve-O Radio™ El Steve, if it worked fine for 3 days and then you got a flicker (black and on screen) it means that your thermal compound is not right or you did not put enough amount of that. I used "Arctic Silver 5 Thermal Compound" from amazon.com ( www.amazon.com/gp/product/B0002EQU6C?psc=1&redirect=true&ref_=oh_aui_search_detailpage ) It worked fine on both PC AMD Video Card and MAC video card. I had the same problems with a "flicker". Try that one. It seams that not all thermal pastes work the same way. Leave you comment if it made a difference. BTW. Make sure that all your vent fans are on. And one more thing, try to connect your MAC to external monitor. If results are the same it will only lead to Graphic Card or its overheating to say it precisely. It is less likely that it was a virus.

You're welcome! I'm glad that I helped.))

I have an early 2006 iMac and this problem has gotten so bad to where there is massive chunks of the screen that are lighter and flashing slightly and lines all over

My pleasure! If you'll buy LCD with inverter attached, do not hurry to throw away your old one. Regardless the fact, that I bought not defective LCD, the inverter, which came along, started to fail in couple months, and I had a little screen flickering. So, I used my old inverter from replaced LCD, which was still good and now I have as good as new stable picture monitor. If your inverter will have the same problem, try this or you may find the same model on e-bay. It's not expensive. Good luck!

Great video!

I have a really bad case of this. My circa 2005 mac os x ver. 10.4.11 has many white lines, a red line, some multicolored lines, and a huge solid black line right in the center of the screen. I also notice that the 'related videos' kinda burn-in at the lines next to the big black one (yes, it is solid black and preventing me from seeing the center of the screen). Please help!

Got a 2013 iMac, same problem, is the procedure the same, obviously different screen ref nos. Seems like this is a common problem, possibly caused by heat over time

I paid $139 for my MAC LCD from e-bay as I wrote it earlier. You may find it cheaper. But I would recommend you to buy refurbished than in "pulled from working MAC" condition. Thank you!

Yes, you can connect iMAC to another monitor with Mini DVI Male to VGA Female adapter(or DVI to DVI). You won't have any vertical lines then, because it's an iMAC screen issue. Any iMAC video adapter issue won't appear as vertical lines. Video adapter problems will appear as random color dots(chunks) on screen. If your screen is blank and plugged in external monitor shows normal picture, then if changing video adapter setting won't help you need to replace inverter, which is in this video also..

2 more suggestions: 1st if your MAC has a shared RAM with video card, you may try to replace each RAM module (on the bottom of screen for iMac) with another compatible RAM (by type and speed) Try and see if it was the reason. 2nd check power board and motherboard radial capacitors' heads. They must be straight flat and clean, with no electrolyte on it. This also could be the reason of cooling fan stop and as a result - overheating CPU or GPU. But If ext. monitor will work, then it's yours LCD.

Serge, I'm looking for a fix for a 2006 iMac. Many vertical lines later, 1/3 of my screen is now dead. I haven't the foggiest on how to adapt another monitor as an external source. I have a monitor spare from my previous powermac (mid-90's) which should still be functional. HELP!

Am I understanding you correctly? You want to use your old LCD from powermac like G5 with iMac 2006? This is not going to work. To replace your LCD you ought to follow the steps in this video, find a model number on the back of LCD, then find this LCD on e-bay. If you have a spare monitor (not a computer which looks like monitor) I see no problem to connect it via Mini DVI to VGA Adapter (if your monitor has VGA) or by other cable adapter which is applied for your monitor input as a temporarily solution.

Your are welcome! )) If you have iMAC with clutches on the top as in this video - this is the problem why it feels loose. If you did not break, accidentally, this latches or plastic where they snap on, you just need to re-seat them again. Did you get what I meant? - Two metal hooks with springs on top inside of white frame (front cover) which you put over the LCD. It's possible, that they were bended too close to the top of frame. Unscrew bottom screws of the frame again, bend this hooks away from top of the frame for about 5mm, then put your frame back on. Press firmly top of frame toward back cover. You should hear clicks (on left and right sides). I've made the same mistake at the first time. Also, you should do this because your CD slot may not match with your frame slot and you may have troubles with loading or ejecting your CD disk. Good luck

- about 9 months. But as I said, it all depends on a condition of screen, that you buy, actually not LCD itself, but permanently attached electrical circuit with microchip, which controls LCD signals feed. Failing of this chip, gives these vertical lines. You can't replace it, unless you have special soldering machine. Anyway, the cost might exceed a replacement of whole screen and you might not have 100% of successful contact connections in case of chip replacement.

Try to connect it to external monitor. If you still have the same picture. There are 4 suggestions: your Video card driver needs to be upgraded your last installed application in conflict with video card driver you might have unsupported screen resolution your video card memory is malfunctioning. First 3 fixable in Safe boot (press and hold Shift key immediately after your Mac starts up) The last one fixable but at cost of Motherboard replacement, because Video card usually is built in in MAC's.

You're welcome! ))

Try e-bay. In this video I instructed where I found mine and how to define where to find what is the model.

Then you might include a list of compatible screens with LM 171W02 (TL)(B2), the ones which fit by size, inverter type and brackets placement.

do you have to buy that battery part or what like is it required and if so whats the exact name thanks

@SergSpace

I'm not quiet sure what's the battery were you referring to. LCD has no battery. It comes sometimes with inverter which lights up fluorescent lamp of LCD. Assuming that we are talking about inverter, you can take it from your old LCD if it did not come with new one and connect it to your replacement LCD. Part number of LCD inverter usually marked on inverter board. If you were talking about capacitors which have a resemblance with battery then yes, I have to buy those, they cost about 3 or 4 dollars or so .It depends on capacity and voltage. At 6:54 of this video you may see where to look for the nominal capacity and voltage. Every capacitor has its own numbers. This type of capacitors called are RADIAL Electrolytic capacitors. They have a polarity. Don't mess up "plus" and "minus". Minus is marked with white stripe and usually shorter (if you buying a new one).

depends the mac screens are proprietary to the plugs but if you get a converter from the output of the pc on the back you can get a good picture thats only if you know its not your graphics chip if its your graphics chip give up and buy a new mac if you have no experiences with soldiering or electronica because you need the correct machinery time and experience. it takes several years to get good at this stuff

These lines are not going to come back as long as replacement screen is in a working condition.But also you should check M/B for bad capacitors. If you were lucky to buy used but working (preferably refurbished LCD) it will resolve the vertical lines problem. But I can't personally vouch for the quality of sold to you LCD. My iMac screen is still working. Was it worth to change the screen? - Sure it did, at least for me, and perhaps, for everyone else who does not have a money for new computer.

Amazing how much the price of imacs has dropped since the new ones came out. You can get a 27 inch 2011 i5 for 100 bucks

This is more of replacing a screen not repairing the screen

hey serg just thought id let you know that this is also a issue on the 2007 and 2008 imac a1224 models i just bought a imac a1224 for 20$ off ebay and it has this same issue it has about 8 colored lines on the display! i bought it as untesed but it turns out it works minus that issue...

You say "new". If it's still on any warranty you can use it to fix for free or return it if it's possible. Anyway it looks like your LCD screen is defective and needs to be replaced. It's could be not as new as advertised. If you ask why line shows up after certain time, well defective semiconductor does not keep up within nominal characteristics at certain temperature point, which inevitably will go up after couple minutes or in your case - 20.

But I doubt that it will help, because this is semiconductor problem, not software.

The same way - by replacing LCD screen. If your macbook is not "Air" then it should be easier. You have to check if there are hidden screws in front of the bezel (frame), usually 4 in total in corners, pull bezel by peeling from inner side. LCD will be exposed. Check where it is connected with the lid by screws and unscrew them. Check model number on the back of LCD and find the same one on e-bay or so. If you need step by step instructions there are plenty of videos on KZread, just search by key words "macbook lcd replacement"

There are plenty of videos on KZread of how to do it. If you won't see these colors on external screen, then you may need to replace your MAC screen, following my tutorial. Also, you might just check the connection between screen and logic board first if it's not loose (but it's less likely though).

I've just checked this web site, they sell this adapter for "standard laptop style 17" LCD screen"? What's the standard screen? From what manufacture?

Jann Goldberg I don't know what to tell you. Cost of LCD for your G5 perhaps as same as G5 itself nowadays. G5 is too old model. At the same time G5 on e-bay has about the same price as Intel based iMAC (2004-2006) around $160-180 or so I saw it. So in your case it's easier to replace your G5 with iMAC 2.16GHz (or so) based on Intel Core Duo. Check e-bay. But if you have no such amount of money, you can buy cable adapter from to connect your MAC to PC Monitor or to your TV if it has VGA input.
