Re: Panasonic TX-L47E5B Image Problem?
So cleaning that tab fixed the solarization? Just when I think I'm starting to catch on that t-con and solarization go together this stuff happens.I assume no responsibility for any stupid suggestions I might post.Comment

Re: Panasonic TX-L47E5B Image Problem?
Yes I initially thought it was solarization so changed the Tcon but unfortunately no difference.
Then heated the BGA chip on the mainboard but ended up frying it. Replaced the mainboard and annoyingly absolutely no difference.
Finally decided to look at the tabs and post#16 picture shows what I found. That tab was in line with the feint line running vertically down the screen. Looked like and felt like marmite.
Since it has been cleaned the set has worked flawlessly.Willing to help but I'm no expert.Comment

Re: Panasonic TX-L47E5B Image Problem?
How did it get there? Could this be a "problem" from the factory? I see alot of these sets with distorted pictures.....
Maybe the same guy thats responsible for the 7 blinkers on 2011 models....

Re: Panasonic TX-L47E5B Image Problem?
The panel tabs are at the bottom of the set. The house where I picked up the set did have a young child and I reckon it was probably sticky hands on the lcd panel that when wiped off run down between the panel and plastic enclosure. But just guess work.
I don't recall any blinking of the front panel leds.Willing to help but I'm no expert.Comment

This TV was showing a fine image and pulsing with a partial double image (offset vertically) every few seconds. I taped 8 clock pins on one ribbon cable from the Tcon to the panel. It stopped the double image, but some pulsing in intensity was still visible. I then taped another 8 clock pins on the same ribbon cable and the image is now ‘fixed’. Although I understand this results in some loss of resolution, presumably because the clock signal degrades as it passes horizontally across the screen.
I am wondering - do these symptoms and ‘fix’ mean that it’s a Tcon fault or... -
Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
LCD displays a 2nd image slighty offset vertically. And multiple pairs of black lines along the bottom. Probably common as google "TCL 49S405 double image" pulls up this ifixit post ( link ) with identical ( nearly, but their fault seems to be on the other half of the panel than mine ) problem without solution.
This one looks to be a more difficult to diagnose because most? of TCON seems integrated ( CSOT BGA on buffer baord) into the left panel edge board ( looking from rear of TV) There are 2 buffer boards for each 1/2 of the screen. Main connects to the left buffer board... -
Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
I have a Panasonic LED TV TC-40A420U. The TV was given to me as an attempt to fix or throw out. I replaced the Backlight LEDs and now the screen lights up, but there is no image/display. If I play with the up/down buttons I can get the display to change from black to garbled. I can't get sound from HDMI but not sure of what input is selected. I have no remote control. When I connect a laptop to the HDMI ports it recognizes a Panasonic TV for display and sound output but I can't see or hear anything through the TV. This makes me think the mainboard is OK, but not sure if mainboard can...
