Panasonic CP830FP bekapcsoláskor Q401 ST310DHI zárlatos lesz (Megoldva!)
Sziasztok! A javítás kezdetekor az alaplapon látható volt, hogy a D406 dióda ketté van törve. Tovább vizsgálódva kiderült, hogy a D367 dióda zárlatos, az I301 (TDA8358J) 6-os és 9-es lábai között zárlat van.Ezen kívül a Q401 (ST2310DHI) tranzisztor is zárlatos volt. Amit eddig csináltam: D406 dióda csere, D367 csere BZX33-ra,I301 csere, C411 (3,3u/160v) csere, C401 (100u/25v) csere, Q401 csere 2SC5696-ra, Q402 (2SD1207) csere. Ellenőrízve a következők: D404, D410, D360-361-362, L380-381, L402, C410-404-405-417-416-425. A Q402 bázisától az I502 H-out (23-as lábig) mindent. A körben lévő összes ellenállást(értéket mérve) ellenőríztem. Új tranzisztor berakásakor egy pillanatra felhúz a nagyfesz, és már zárlatos is Q401. Köszi a segítséget: kisember Inpulzus kondik, sorkimenő, és a második TDA 8358J csere után a TV szépen működik. Még egyszer köszönet Mindenkinek! Üdv: kisember
RGB Mod in Panasonic CTP-2780SF

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.

Panasonic tx49dx600e nem kapcsol be. 13-as hibakod. Megoldva
Üdv!
A gép bekapcsolás után zöld led nagyon sűrűn viloog majd zöld led megmarad. Táp megy, de a háttér nem, Bl onon nincs semmi. Egy idő után kiáll 13 villogásra. A mainen sincs pl 12v amit egy kapcsoló táp állít elő, de az ic itt sem kap enable jelet.
Main száma TNPH1160. Esetleg eladó vagy ötlet a javításhoz?
 A hiba az emmc újraírásával megoldodott
