    could be, did you try reseating your tcon cable and ribbons? careful with the ribbons, use fingernail to pop up retainers, can check youtube tcon replace for a video, if you like.

        Look closely at the bottom of the black bar, it looks like an impact point.

              Definitely looks cracked to me... that can't be anything but impact damage. Unrepairable.

                  no problem at all, at least there was a conclusion, too bad about the broken screen, looks like a nice tv otherwise.

                      can't seem to get ahold of any plasmas, but I like the good clear picture on lgs and sonys.

                            Trust me if you are a beginner at repairing tvs stay away from plasmas untill you gain more confidence, lots of things can go on them.

                              I think plasmas are easier than LCDs. You just need to know what to test. 9 times out of 10 I can fix a plasma by doing five simple voltage checks.

                                I find the voltage testing and short testing easy just like lcd its just alot more work as the are lots of buffers and sustain boards to test. And if you have a bad y sus repair it and the x sus is also bad it will take out the new y sus just basially alot more work.

                                  Hm, if you say so. A little testing can eliminate that risk. Always use a light-bulb tester when testing plasmas on the Vsus rail.

                                  Bad master-slave inverter can also destroy opposite inverter (had that on a Sharp LC-52XL2E... what a nightmare.)

                                    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...

                                    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...

                                    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....

                                    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 iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...
