I have a westinghouse tv (EW50T5KW) that has horizontal distortion, like an old TV broadcast that has poor signal. If I unplug 1 of the ribbon cables from the t-con board, the problem goes away, of course this is blacking out half the screen. I bought a used t-con board off E-bay and it has the same result, both t-con boards also makes a high pitch whining sound, until I unplug 1 ribbon cable. Do you think I have received a faulty t-con board, that coincidentally has the exact same issue, or could this be a video board problem? I have cleaned the ribbon cable ends with alcohol to no avail. Also did some tapping around with my finger while it was on (staying away from the power supply) and it does not seem to change anything on the screen. I can post pictures, or even a video on Youtube of the screen distortion if that helps. Thanks for reading.

Re: Westinghouse 50" TV (EW50T5KW) distortion
Can We Get A Picture Of The problem? Sounds like a bad panelDid I leave the soldering iron on? -
Re: Westinghouse 50" TV (EW50T5KW) distortion
Sounds like a panel problem, was there spray cleaner used on the screen?
Posting pictures of the guts of the tv will help.
Also if there is damage to the LCD TFT tabs then the panel is toast, only way to check it to break the panel down to the TFT board that the t-con is plugged into.Comment

Re: Westinghouse 50" TV (EW50T5KW) distortion
Yes, I will post a picture as soon as I get home tonight (2am). I suspected the same thing but, when I unplug the 1 ribbon cable from the T-con board, the 1 half of the screen looks perfect. I thought if the panel failed, then the whole screen failed. Thank you for the reply, I think i might post a video on Youtube. I will post a link when I get home.Last edited by pottzy87; 12-11-2014, 10:04 PM.Comment

I don't know if a cleaner was used on the screen, as it is a friends TV. I will ask him tomorrow, we are on separate shifts.Comment

Re: Westinghouse 50" TV (EW50T5KW) distortion
I think I have found the problem. Upon taking it apart further down to the panel, I found one of TFT ribbons had a burnt or shorted silver area. Thanks anyway!Attached FilesComment

This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
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... -
Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
Good day, I have a TCL TV: Model 43s423. After turning ON the TV, the ROKU TV logo appears with fine lines over the whole screen, then after a while there are vertical bands in the middle of the screen top to bottom and the TV tries to update its firmware but I do not have the remote to connect it to my new network connection. Also the Power ON light blinks 2 times in quick succession. When I remove the ribbon on the right of the tcon board the left side of the screen shows but with fine lines. If I remove the left side ribbon and connect the right side ribbon the whole screen is blank with... -
Hi,
i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.
Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.
Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?
Appreciate your help....
