Sziasztok!
Tudnátok ebben segíteni?
Zárlatos volt az egyik videovég, cseréltem mind a 3-at, de csak
csak raszter van.
Cseréltem eeprom tartalmat, de ugyanaz.
A katódokat leraktam testre egyenként , virítanak
A TDA4780-n a következő DC szinteket mérem:
14 pin 0,7V
15pin 4,1V
16 4,5
17 4,4
18 1,2
19 2,5
20 0,7
21 1,9
22 0,7
23 1,9
24 0,7
25 1,9
Megszkopoltam a TDA4780. A SC-t megkapja a 14 pin-en , a hajtást is .
a 20, 22, 24, gyakorlatilag semmi nincs, ezáltal a videovégek 9 pin-en sincs jel. A
19-en van valami 2 Vpp jel, de tv miniscoppal csak hasonlít.
Szereztem egy TDA4780-t de azzal is ugyanaz.
Itt egy rajz:

Zárlatos volt az egyik video vég, fogta a 200V-ot. Kicseréltem, de csak annyit csinál, hogy ha feltekerem a G2-t visszafutási csíkos raszter van. Hang van, reagál mindenre.
A katódok 186V-on vannak, a cső A66ECY.
