Re: Samsung hd rear projection tv crt subtle wavy lines on displa
Any progress on this one? Just curious on the outcome.

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
No sorry.....im being told it could be capacitor interference but since all caps visually look good im stuck
There are many caps on the ps and input board......
The distortion is very random and gets worse and better throughout watching a tv show
Would like to fix but not sure which caps to pin pointComment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
If you have a scope that would help, if not try some heat to certain areas and see how it effects the lines.
Try using component input (Y,Cb,Cr) and try different resolution ie:1080i and see if it effects the lines.Last edited by R_J; 01-18-2018, 09:43 PM.Comment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
the distortion is on all inputs ...doesnt even matter if video playing or not....
Dont have a scope nor do i even know how to use one anyways
Ill try heat one day see if it affects the distortion or not....what area should i concentrate on.....input board or power supply?Comment

Dont have hd tuner"....so its not hd signal....its standard non hd resolutionComment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
What about a dvd player into the component inputs?
I would try heating caps. around the power supply/deflection area first, the switching power supplies run at a high frequency so if the output is not filtered properly that high frequency wave will show up in the video. but which line, thats where the problem comes in.Comment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
Typical symptom of bad convergence modules.
Most times these can be calibrated in service menu till totally failed.Comment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
This is not a convergence issueComment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
Hi
Im sorry but i have little knowledge in tvs but i am pretty sure its not a convergence issueComment

Re: Samsung hd rear projection tv crt subtle wavy lines on displa
I have had failed convergence chips go bad along with resistors and agree that this doesn’t appear to be a convergence issue. All three colors appear to be in align.

Hello,
First of all I'm new here. While looking I found this amazing forum and I'm very happy I did. Now for my problem:
I picked up a Samsung UHD QLED QE50Q67TAU from 2021 for $50 knowing it was defective. The seller said it had black lines and that it could get stuck in boot randomly.
I've tried a new power cable, hard reset, opening up and jiggling all cables, pressing everywhere to see if I get a reaction but I've gotten nothing. I've tried the tape method but I've only managed to get the lines worse.
I'm no expert but I've done the tape... -
Hi all
I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):
This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!
So....i don't know what end of the C ribbon to work with... -
