                  I would check the tab bonds just to be sure. That's the exact same symptoms my Sony KDL-46XBR4 had when I got it. Half the screen dark with horizontal bands and ghosting.

                      you can likely save the panel using the tape cutoff method that uses a piece of tape to block some pins on the tcon if there are no side tabs. if there are side tabs, then the save involves removing those on the dark side and the picture will be good. lots of threads on this type of save.

                          Only applicable for the larger panels that have two drivers, one for each side.
                          It's a 48" Panasonic likely using a cheap Chinese panel by TCL, so who knows? But seems unlikely.

                              IF there are side tabs....otherwise try the tape cutoff method.... it will likely be saveable

                                  LG 82UN8570AUD ~ TCON or PANEL?
                                  by kca
                                  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...

                                  Driving a Sharp TCON/panel with a universal main board
                                  by advant
                                  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...

                                  Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                                  by Ryan.man
                                  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...

                                  Lg TCon test pins for screen test
                                  by alltvrepairs
                                  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....
