Sziasztok! Több rossz alkatrész mellett szétszált a D431-es smd dióda, a SM-ben ezt írja: D431 - B0JCDD000002 Egy német fórumon ezt írták: D431=B0JCDD000002=RB1819A, na de ez sem segit mert az RB1819A-t se talál a Google.. Mit tegyek be helyette?

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:

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.

 

Kedves Tanyalakók!
Adott a fent nevezett TV.
Csak a készüléken lévő ki-be kapcsoló nyomógombbal indítható kb 3 másodpercig nyomva.
Beindul de csak a Panasonic logo jelenik meg. A feszültségek rendben látszanak, de nem megy tovább, A távirányítóra a jelző led reagál, de készülék nem. Sem ki, sem be nem kapcsolható távirányítóval. Minden tipp jól jön.

I got a broken Panasonic that will not start. It does show the red front LED and the power supply delivers 5,3Volt standby. Only when you try to start by remote or push button on the set it will only flash the red LED and does nothing more.

After a while, the red LED will start to flash repeatedly 13 times.

Since the 5,3 Volt standby run straight to the main board I wanted to check there but no luck finding the schematics.

Any insights?

After several attempts the TV finally started and I could enter the menu screen. Normal functionality. But after switch off it takes again several attempts. What is going on ?
