Panasonic TX-L42ET5E nem indul
Sziasztok !

A fenti tv, 13-as hibakóddal le áll.

Ha minden igaz, IC8101 ( C0DBAYY01285 ) 1,5V -os stab IC okozza,de nem beszerezhető.

Tudnátok valami megoldást ?
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 TX-28LK10C/S chassis EURO4H hiba: F-board TNP8EF007 kontakt hiba
Tisztelt Tanyalakók! A fent nevezett TV bekapcsoláskor van hogy beindúl, van hogy nem. Odáig jutottam, hogy a (IC 1504) 8-as lábára tettem egy oszcilloszkópot és ha ott bejön a vezérlő jel, akkor az eljut a Q503 G pontjára és a +B1 209V megléte után szépen megy míg kinem kapcsolom. Ha a 8-as lábon nincs jel, akkor a védelem 4 mp után kikapcsolja a RL801-es relét. Ha a F-boardot feszengetem, akkor beugrik a jel és megint elmegy. Ha sokat vacakolok vele akkor meg jó marad, de csak a következő bekapcsolásig. Már minden forrasztást átnéztem, de nem találtam repedést. Az IC-t nem tudom újra forrasztani eszközhiány miatt. Ha valakinek esetleg lenne egy ilyen F-board panelja, akkor én meg veném. Köszönöm a figyelmet. Üdv. Mekmuki
Panasonic TX29PM1P CP521F sortrafós-e?
Sziasztok! Fene tudja honnan van már, emlékeim szerint trafósan hozták. Nos, bekapcsolva szépen szenved a sorvég. 1000% a sortrafóhiba? Ahogy látom ezeknél sokszor döglik be szegény. Nem jutok hozzá, csak megint egy hét múlva kb, addig pihen. Üdv: Pityesz
