Re: Lg 50PX4DR-UA lines in screen
My guess would be the logic/control board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Lg 50PX4DR-UA lines in screen
Is there anyway I could narrow it down to that? Do you think freeze spray could help?Last edited by pop70458; 04-13-2014, 07:19 PM.Comment

Re: Lg 50PX4DR-UA lines in screen
Is the fault intermittent or always there?
Not much you can do re narrowing it down, although the logic board generally is the only board to process the picture in two distinct halves like that, if that helps you decide.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello, 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... -
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... -
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... -

My Panasonic Plasma model P55VT50 has started displaying "interference" on just the left half of the screen only (left when facing the screen). Sometimes it's concentrated in about the first 30 seconds after startup, then disappears. Other times it's fine at startup and then randomly does it later on. When it flashes the interference it's very quick and doesn't stay on the screen unless it flashes repeatedly in a row.
This image is a screen shot from a video I took. This is an example of the interference at its worst. Often the interference is much smaller...10-14-2022, 04:54 PM
