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...01-06-2025, 06:02 AM -
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,... -
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 😀... -
Hello, I have an PANASONIC TX-P42X10Y Plasma TV, purchased new in 2009.
Unfortunately plasma is not working at all after a power spike. Standby LED is not even working.
I did some quick tests, YSUS + ZSUS MOSFETS and IGBT's are free from shorts, diodes on these modules seems to also be fine, buffer board is free from shorts as well.
Anyway I focused mainly on the PSU, did some voltage tests with the results as below, I attached them on the photo (also please see attached PDF with the SERVICE MANUAL for this model, page number 43).
I understand...
Working...
