Re: philips 37PFL7662D screen fault
Please do more investigation and post more info detailing the problem.
Does this happen upon powering up?
Does this happen on all inputs?The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

Re: philips 37PFL7662D screen fault
I have exactly the same issue, black banding on the screen as shown above. TV works fine for about an hour or so usually then the black bands appear, and can sometimes disappear again later.
Question ... is it worth having the buffers replaced?Comment

Re: philips 37PFL7662D screen fault
LCDs do not have buffers. This looks like a panel failure. Tab bond failures cause this to happen on LCD TVs.Comment

Re: philips 37PFL7662D screen fault
Hi.
I have the same problem. I bought this TV on july 2007. The problem started around 1 year ago. To solve it, I have to knock on the left -in the middle and top left-. Also, when the TV has beeing switched on about 20 minutes stops to do it. I don't know how much time will resists the hits... As time passes I have to knock it harder...
At first months was just a soft knock, not like know... also the black spot is getting big, sometimes almost full screen, but on the left is more black, than the right where is like with red color saturation.
Any one found any solution?? Any one tried to repair it through Philips Official Service? How did it costs?Last edited by gabicach; 05-25-2013, 10:57 AM.Comment

Re: philips 37PFL7662D screen fault
It is a tab bond problem, just like this:

Re: philips 37PFL7662D screen fault
Hi!
Do you think really is a tab bond problem? That would be so cool, because the repair it seems so easy.
I uploaded a video with my TV problem on youtube, I recorded this video just after turning on the TV, as I said, after some minuts working, it starts to be OK:

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.
The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While... -
i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
