Panasonic TC-P Series Vsus Voltage

[dcapper]

I have a TC-P54G20 that I cannot find the proper Vsus voltage. There is no sticker and none of the service manuals show what the proper voltage is. Mine is outputting at 194v. I have read posts that it might have to be 204v. I received the tv broken and the old owner tried to fix it, so who knows if he adjusted it. Can anyone confirm or has anyone got a P series that they can meter the Vsus for me?

Re: Panasonic TC-P Series Vsus Voltage

The series for your Panasonic TV is G20, not P.

A low Vsus can cause:
- dimmer image (~10% dimmer)
- dead pixels or pixels sticking
- pink tint to the image especially in the middle of the display

It cannot however cause no image unless it were completely missing.

I would run with it at 194V and see how it goes. It is quite low for a modern plasma TV, I would expect higher, but Panasonic has been among the least consistent manufacturers with regard to their Vsus voltage. Up until late generations their 42" & 46" panels were still hand calibrated with different Vsus for different panels.

Ah I see. G Series not P. I find at 194v there is green pixels if you are up close to the screen. I was discussing this in another thread with TW. But he didn't know if it should be 204v.

Green pixels up close: turn down the brightness setting in the user menu until they disappear. Plasmas tend to dither (display noise) especially at low light levels due to bit depth loss at those very low levels.

Ok. So I should leave the voltage at 194v too? Also, should I set the Vsus level to high in the service menu?

If you don't notice any of the symptoms I list above leave Vsus as is.
