    Re: Panasonic Viera TX-P42VT30E TNPA5330 blown

    I know, but right now I (or the authorized service) don't have it.
    I'll order one to have on-hand, just in case...

        You could buy a SS board and use those parts. These boards have all the parts you need. They are cheap because they never fail or buy FGD4536TM from ebay.

            I still have the order of FGD's placed, but they will arrive withing 2-3 weeks...
            I thought about buying SS boards, but I think I need two to cover all 6 FETs. I am not sure right now.

                I will check to see how many are on the SS board when i get home. I got a few of these boards.

                    I googled on TNPA5331 and there are 6 fets on the board you can use

                        Thanks for the tip about SS-boards, I'll keep an eye out in case of repeated problems.

                        Hopefully final update:

                        TV ran ok until now (about 4 hours). Re-assembled everything, started up, all ok.
                        Temperature in the area of the FETs is about 30-35degC at case surface, 35 with very bright pictures and a lot of ambient light (outside of the TV, K thermocouple taped to case).
                        Hopefully that DG302 from the shitty kit will hold, as I am sick and tired of taking out all those screws

                        Many thanks to all that contributed, special thanks to Moreno83.

                            You are welcome! I am glad you fixed the tv , great model with very nice picture quality. How is the burn in?
                            The DG302 is probably ok otherwise you would have had 6 blinks.

                            Did you check the contacts on the back of the sc board? Usually they are black because of arching....

                            You can recognize the fake parts by the logo. The Fairchild circle on original components are engraved in the fet. The fakes just have a stamp.
                            With isopropanol or nail polish remover you can wash off the logo from fake parts. Original parts the logo will get visibly better....

                                Indeed, great colors, beautiful image. There are some slight burn-in marks in the corners, where the channel logos usually sits and in the bottom area where the subtitles are, but not visible under normal watching conditions. They do show up tho on a full white picture...

                                That was the first thing I did after taking out the boards. Indeed, scorching occurred on all three planes of contact, the metal chassis, the board and the screws undersides. Cleaned the chassis and the screws with sand paper and took out the affected solder on the board.

                                    I'm happy to report that the kit DG302 transistor holds up just fine, the TV is still working great after these few days. I imagine that if it was to break, it would have done so by now.

                                        Yes the DG302 is probably a good part.

                                            by Ama Chur
                                            After watching some youtube videos and checking some forums, I'm at a loss. With both ribbon cables connected, we have no image. With the left one pulled out, the screen is black and white, split down the middle. With the right cable removed, it is all black. Backlight is working fine and we have sound and can open applications. We are strapped for money right now and are hoping to repair whatever the issue may be. I think the TV was manufactured in 2012, so I'm aware that may not be possible. Edit: Found a single vertical line of blue pixels on the left side of the screen with one of the ribbon...

                                            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˜€...

                                            Hi,
                                            the TV has a black screen. Sound OK, backlight OK.

                                            When I measure T-CON voltages, there is VGL+VGH=0V. After unplug the right side of the screen from the T-con, voltages are OK and half screen works normally.

                                            I tried to search for any kind of short on the right side, but I had no luck. I have a beginner experience in measuring and repairs of the LCD panels..

                                            Thanks to anyone who can guide me in solving the problem.. and be patient with my english πŸ™‚πŸ˜

                                            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˜‚.

                                            I have here a Plasma TV TX-P46G10E that before had a problem where it had issues with 11 blinks (FAN SOS) BEFORE starting normally. After that it works for all day long.
                                            It had some bad cold solder and I remade them all. After I replaced a fan that was half-dead (no RMP signal from the respective pin, but ok with 9V).
                                            Now the TV power up instantly and works perfect... only without the backplate!
                                            If the backplate is placed on the TV shutsdown after about 10min and start blinking with the 11 blinks. If I shutdown and re-powerup it starts blinking after a bunch of...
