    Re: Panasonic Plasma fault

    The cheap parts that blew up did more damage to the board. I cant find that model number here in the USA to look at a pic of your board.

    I had the same problem , never fixed the board....

    Panasonic Plasma fault

    Hi All
    Ive got A th-p50vt30z plasma was going perfect till it got the 7 blinks of death
    so i replaced the faulty suspected transistors with some cheap ebay ones
    tv went for a few hours the Pop blew up again.. after seeking advise was pointed to a reputable source so got more transistors and replaced those
    now tv turns on to a solid green light ,displays some garbled writing for a split second and stays a black screen
    still faulty board or had something else got damaged in the process?

    Panasonic SA-MAX770PU SMPSU board fault....
    by Rictech
    Hello everyone. 😀

    As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
    Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

    Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
    This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
    There are no devices that have exploded or otherwise show signs...

    Panasonic ZT60 plasma tv with strange behavior and 8 blink code
    by cloo
    I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
    It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


    So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
    After doing a factory reset this problem was gone and the picture was back to...

    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 P42S30 Plasma - Pink sparkles
    by Lintesir
    My parents' Panasonic P42S30 died recently, and they asked me to have a look at it. I was able to identify the SN-board as the culprit, as it was shorted. After removing Q401, Q402, Q421 and Q422 the short was gone, so I replaced these components and that got the TV working again. However, when testing the tv a bit, I noticed quite bad pinkish sparkles on some colors. For instance the greyish bar on this forum seems to trigger it quite badly. I made a fullscreen test picture with only that color, with the below result.

    There is about a 5cm high region at the top without any sparkles,...

    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 😀...
