    Panasonic plasma colorful screen

    Anyone had this issue before? Tv boots up, screen comes on, with a screen full of horizontal eeprom corrupted kind of colorful lines and gives a buzz on the speakers then goes to standby mode with 14 red blinks which narrows to A board (Mainboard) according to service manual. Anyway to fix this issue? Looks more like a corrupted chip to me.

      Almost certainly main board, is the on-screen display OK (menus, etc.)? It looks ok in that pic.

          That looks like a BGA Processor or RAM failure. Replace main if you haven't got rework tools.

              A close up on the BGA's. Which one might that be?

                  If i were to guess, i would say it's the biggest one on the board, but for a real opinion you're going to have to take the heatsinks off so we can see some part numbers.

                      The biggest one is the PDP controller. Failure of that will cause maldischarge and shut down faults.

                      The most likely candidate is actually one of the smaller ones in my opinion. I'd say the middle/top one is the main controller / applications processor and the one on the right is a HDMI or input processor, but it's hard to say for sure.

                          Problem solved. Replaced main board. Got a good condition used board for 40 bucks.

                              Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
                              by Alicat
                              Hello,

                              Stopped by this site trying to fix my parents Panasonic Plasma TV.

                              Model number is TH-50PZ85U

                              Power comes on and the red power light stays on solid.

                              Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

                              I also hear a few clicks.

                              I also think my parents said there was a thunderstorm and the TV failed after that.

                              Section 6 in the service manual talks about power and no screen,...

                              Panasonic Plasma screen interference on left half of screen
                              by Zelek11
                              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...

                              panasonic TH-42PC77U plasma television half screen problem
                              by renech
                              hello,
                              I hope someone on this forum can assist me.
                              I have a panasonic TH-42PC77U plasma television.
                              the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
                              i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
                              I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
                              I have read some posts that suggest the problem is related to the boards on the left...

                              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...

                              Panasonic TX-48CX350B backlights but white screen , blank screen
                              by Chrissygizmo
                              Hi all, I’ve got a problem I hope someone can help me fixi.
                              I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound. I’m not sure what the fault is called whether it’s BLANK/ BLACK/ or WHITE SCREEN I’ve actually came across this before on a similar tv but just ended up scrapping it, I will upload pictures of the boards etc , if anyone could help me I would really appreciate it...
