    Panasonic Viera TH-50PZ80U right side black

    Well, as the title says, my 2008 plasma Panasonic has a black right side (looking at the screen). The left side is readable, but being a multitude of incorrect colours and the sound is fine with no blinking red power light. Ive unplugged it overnight, tried again in the morning and same problem.

    My wife was watching tv when it happened, the TV having been on for about 20 minutes when suddenly the right side went out. Ive checked all the exterior cable connections, the only thing I havent tested is our satellite receiver as that would require a lot of shuffling of TV's. The other TV works fine so if it is the sat. receiver, its the output to my plasma.

    Ive built my own computers for years and have no problems digging into the guts, but before I do this to a TV I need my ducks in a row because I havent done that before.

    I must say this forum has an AMAZING amount of information!

    Any help would be appreciated, thanks.

    Loose LVDS cable is a good possibility. I fixed a 46" PZ80 with this fault and kept it for about a year before giving it to a friend. Here's a video:

    Should apply to the 50" as the 46" is nearly the same (the 42" is slightly different, but issues with LVDS cables also affect them.)

      Hi again, Ive wiggled the cables along the bottom of the set, finding one that reseated itself with a very quiet click, just to the left of the flash glare....hopefully the file loads lol. Is this the LVDS cable?

      I tried entering the diagnostic screen but pressing volume down on the set while hitting 0 on the remote 3 times quickly produced no results. Is this procedure different on the 50" than on the 46" in the video?

      Do I need the TV hooked up to an incoming signal such as the dish or dvd?

        Yours is a US model so it's a different procedure to enter service menu. Did the reseat resolve the problem?

          No, it didnt. I was going to go through all the cables shortly, was just waiting for my 30 minutes since unplugging it so I dont get zapped. I should have got on this sooner but its summer and the outside 'honey do' list is quite long this year

            The cable you need to wiggle is right near the power supply, running between the A board and D board. It's brown or red, many thin wires.

                Just make sure it's securely seated, and it should be perfect - mine was good for over a year and went through a couple of house moves no problem.

                  Looking for help diagnosing a 65" Panasonic Viera TV - TH-65DX700Z (Turns on - Clicks - Turns off)
                  by mostachio
                  Hi Badcaps,

                  I've had a friend discard a TH-65DX700Z Pansonic Viera Television and I've decided to have a go at repairing it. If possible could I please get some advice in terms of diagnosing the problem so I can purchase the appropriate parts for repair whether it be components, a repair kit or a replacement board. I am happy to post pictures if required.

                  TV Details:

                  Model # - TH-65DX700Z

                  Symptoms:

                  The television turns on and displays a picture then makes a clicking sound and turns off.

                  I haven't opened it up yet but...

                  Dead Panasonic Viera TX-P65STW50 Plasma TV
                  by badcappo
                  Hello, got a ST50 plasma TV for repair. No signs of life, not even blink codes. Opened it up to check the power supply, type MPF6914. Apparent issues from visual detection and measuring for shorts:
                  Diode type G972s6 - D101 with a short
                  Mosfet 06N90E - Q301 shorted
                  Fuse T5AH 250V - F103 blown
                  Diode D301 shorted
                  Relay DG1U-17VDC II - RL001 blown

                  I have not found a circuit diagram. Maybe someone here already dealt with a similar issue? Thanks for tips where else to check πŸ˜€...

                  Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
                  by flibidy
                  I have here a Magnum IA.100 which belongs to my parents.



                  The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                  Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


                  What Ive done........

                  Panasonic 55DX600u second fault - panel brightness pulsing on right side
                  by fixxy88
                  After getting the backlights up and running a second fault has emerged on this TV. I was going accept defeat and move on but thought I'd have a quick look at it in case it was something simple. The right side of the display exhibits a panel brightness (not backlight brightness) pulse every 2-3 seconds in a stable timing.

                  I poked about on the TCON test points and found one voltage that is fluctuating in the same pattern. VGH-ODD (Pin 47 of U10) is sitting at ~-6.5v then goes up to ~28v when the brightness pulses then goes back down to ~-6.5v again in a repeating pattern.

                  Panasonic TC-P55ST50 8 blinks then no blinks
                  by Andre Gilbert
                  Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing hereπŸ€”?
                  Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.
