Hello, I am working on a panasonic tv that shuts down a few seconds after it comes on, blinks(red standby light remains on)three times pauses, and repeat the cycle. Any ideas as to what could be wrong? Thanks.
Sziasztok!
Tudnátok segíteni?
Lenne ez a gép. Random módon elmegy a kép, visszajön, elmegy stb., majd
kikapcsol, és 8-at villog a stby led. Csak áramtalanítás után
kapcsolható vissza .
A csatiakat átnéztem, a földelő csavarokat megtéptem.
Ezeket végigcsináltam amit ír a 8 hibára.

Van valakinek más ötlete esetleg?
Kösz
Anyone ever do one of these to a CRT?
Seems like the set has this jungle IC which will be where the RGB lines
for the OSD are needed for the mod:
https://pdf1.alldatasheet.com/datasheet-pdf/view/13342/PANASONIC/AN5304NK.html
Am not sure what the line would be that tells the chip to turn the OSD on. Apparently there
is a line if its 1 volt or more, it activates the OSD, if zero its normal video.
Also I think there must be a sync line tapped into which is bought out to the rear of the set,
with the (3) RGB lines / jacks but not sure where that would be tapped into?
I am gonna use BNC jacks, not the scart connector.
There are some youtube videos about RGB modding and lots of topics on the shumps
forums but so far it seems no one has tried this with Panasonic.
