Hali mindenkinek! Pár napja hozták javításra ezt a 32"-os 16/9-edes szörnyet, hogy beindul majd pislog a led.Jó, bekapcs, 12-es hiba.Hmm ezt nem értem.MSP nem válaszol megfelelően, ilyen hibám sem volt még..gondoltam.Előszor is a Nagyáramú panelt néztem át,10,3nF lába persze szarráégve, minden nagyobb kondi lába kh.Csere, átforraszt bekapcs.Ledöbbenés. 12-es hiba marad.Végső ekeseredettségemben MSP csere.Bekapcs, 12-es hiba marad.(már nem voltam meglepődve)Visszatértem a nagyáramú panelra,mivel csakis ott voltak a probémák,gondoltam.És valóban, a TL100(cinemaFET IRF630) volt a bűnös. Tanulság ICC20-nál: ha az MSP nem válaszol, akkor a képszélesítő fet a rossz.
Hello,
My son found a good looking old TELEFUNKEN 2931E to the near trash bin.
I didn't want to throw it away, so I decided to test it. Unfortunately, it turned out to be a problem - the power supply part does not work, and there are traces of а previous interventions.
On the regulator board, near transformer.
I managed to find sort of manual, but its different to this particular model. There are some difference in regulator board, where the main problem is located.
Can someone help me finding a service manual for this VCR?
Thanks a lot!
Kalin

Sziasztok!
A fenti videóhoz keresném a kazettabehúzó mehanika alkatrészét, a képen látható hosszú tengelyes kellene akár bontva is.

Sziasztok!
Keresem a fenti VCR rajzát. Szétesett a fejtrafó, ki voltak száradva a tápelkók. Javítás után minden működik, csak a szalagvégeket nem érzékeli. Az IR LED világít és diódamérővel az IR vevők jónak tűnnek. Ha letakarom lezárnak, ha belevilágít az adó LED, akkor kinyitnak (kb. 700mV). Bekötve viszont állandóan 0V mérhető rajta. Próbáltam végigkövetni a vezetékeket, de nem értem, mert egy-egy 33kOHM-on a syscon prociba mennek. Mitől lesz ott értelmes feszültség? Lehet, hogy belül a proci huzná fel tápra? De mind a két bemenet egyformán rossz lenne? Szóval jól jönne egy rajz erről a részről.
