Hi Guys number of things lets start with the black goo "kiss of Death.
I have just went through 5 MS2930 and 1 MS2931.. yes the goo comes from the horizontal drive transformer.
Yes the black goo is a potting compound so not conductive.
Yes can be "kiss of death if not taken care of early, 2 issues the lack of potting compound in the transfomer can cause a failure with the trasformer, or the leaking goop can get into a number of the main board pots such as X-ray protect, sub vertical size and others.
Treatment, remove the drive tarnsformer and flyabak if necessary, scrape with a razor blade scraper and cleam up with Nail polish rover. Either repot or seal the drive transformer with a high grade RTV Silicone, I have not not been able to identify who made the tarsformer or suitable replacement.
Replace pots as needed.
Put i all back together.
Good luck, so far 4 out of six sucess rate.
NOW THE CHALLENGE, can ay one provide good schematics of the 2931, I have a poor one, CAN any one provide a schamtic of the 2930.. desperate on this one.
