Re: Possible purchase
Samsung is bad panel, don't touch it.
I think the Emerson may be too, I can't be sure.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Possible purchase
Agree with cadiman. 9 times outta 10 a vertical stipe/bar/line is unrepairable plasma panel failure.Did I leave the soldering iron on?Comment

Re: Possible purchase
No experience with Emerson, I stay away from them. Is the Samsung a plasma or LCD? If LCD and the price is low enough. I may risk it. Bad panel, yes, but I have fixed most that I have tried to. Just tonight, I fixed a Sharp 52 inch that had half the screen all messed up. One connection point was responsible for all of it. 15 minutes of trying spots on the panel. It will take hours to fix the plastic standoffs that cracked over the years. Still, not bad for $30.Comment

Re: Possible purchase
I got the samsung, its an lcd. FREEEEEEEEEEE.... I figured when I got it back to the hotel and plugged it in that I would be able to flex the frame and she some changes, but I flexed the hell out of it and seen no changes.. The Emerson is also an LCD but I have not heard back from them.. I really dont need any of them, as I have 3 at home I need to get my a** back to working on but hubby and kid have kept me to busy to work on anything.Last edited by lilmonk3; 10-09-2012, 08:52 PM.Comment

Re: Possible purchase
It could still be tab bonds, not always possible to 'clear' them by flexing. May be at the circuit board end.
The Sharp that I worked on was model LC-52D65U. The tabs are on the bottom. The problem was a main connector on the left side. It was not holding the flat connector tight enough. The metal frame is 4 seprate pieces. Took only the bottom one off. Used a piece of dense 'heat sink rubber' between the connector and the metal frame to apply pressure. Will test for several days before closing it up. Still have to fix the cracked/broken plastic standoffs. It is a thin plastic frame model, not very strong...Comment

by howardc64All left and right refers to looking from rear of TV (or looking from front with TV upside down)
- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

by Stanley1843Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

by jeyoung12Hi 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... -
by RubenlilyHello,
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... -
by ggil44Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,
