Jó napot!
Kijelzőt keresek egy Panasonic TX-L32C10P típusú készülékhez, sajnos a benne lévő ripityára törött.
Kijelző típusa: LC320WXN (SB) (C2)
Kérném ha van valakinek baráti áron, keressen meg.
Köszönettel: Comman.
This elderly monster arrived with the error “ 4 blinks “ which the manual suggests is a power board fault
There are TWO power boards and a standby power board inside
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ]
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out
I have done cold checks on both boards and there are no obvious differences
As the manual has only a block diagram of the power supply it’s difficult to be sure of values / voltages
Has anybody seen or worked one of these or similar beasts and managed to diagnose the problem
Thanks for looking
Regards Ken
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.

Sziasztok!
Van itt egy ilyen tv, ami tunerről gyakori időközönként leáll készenlétbe, és villog a készenléti LED, mintha letiltana valamiért. Még nem mélyedtem bele nemsokára belenézek a műhelyben. Forrasztási hibákat kizártnak tartom mert nem olyan régen már javítottam egyéb hibával (képcső csere, + elkók cseréje) ekkor át lett forrasztva ami gyanús volt. Az adatvonalon keresztül kavarna be a tuner, vagy megsérül a kép vagy sorszinkronjel és ezért tiltana le? Mit javasoltok mivel kéne kezdenem?
Kösz előre is!
