Sziasztok!
Egy kis segítség kellene. Van a cp775r sasszis tv aminek elég érdekes hibája van. Leírni nem is tudom, de a képek magukért beszélnek. Tápok jók, rossz elkók cserélve. Kh nincs. Ptk cserélve.
Szerintetek mi lehet a hiba? A képen a két visszintes csik a fényképezőgéptől van. :-)

Szóval most barkácsolok,a régi orosz gyártsu tv k nem takarják le az egész kábel sávot,gondoltam,kidobom a két tunert belőle,és beteszekegy külföldit,találtam is egy ilyen a fentebb leirt tunert,csak a lábai melleti röviditésben kellene egy kis segiotség.
Tehát BU-VT-BH-AGC-BL-AFC-BM-IF,az AGC,AFC ,IF et tudom természetesen,még a VT is gondolom varikap feszültség,szóval a maradék fel irat mit jelent?
Üdv!
Lenne ez a TV.
Csak kék képernyő van rajta.
Mi lehet?
Flash hiba, vagy valami más a nyűgje?
kösz

Hello,
I am troubleshooting a POLAROID TVB55R4PR004 TV which has a short circuit when the inverter tries to start. I checked and replaced some faulty components.
On the card (reference CV3458H-A50), I have two integrated circuits marked PU1 and PU2 which also seem to manage the switching power supply. An inscription RBt 35 CZ is noted on it.
I am therefore trying to find out which component it is in order to be able to find the datasheet or a diagram of the card.
Thank you in advance for your feedback.
Best regards.
