Hoping one of you philips techs can help . I changed the flyback and still
the same. Adjusting screen does'nt help this one at all. I noticed I only
have 127 volts B+. It should be140 volts.The set will not go into sdam
without shutting down continuously about 3-4times then quits.When the
picture comes on it has a 1 inch margin both vert and horiz.There is a UNDER
voltage problem here and I was hoping someone can tell me if there is an
adjustment or a part to change. The 10 volt zener at the photocoupler seems
ok. Is it worth ordering a new 8 pin volt reg IC or has anybody seen a bad
cap or something.This regulator circuit is really tough to figure out.
Any help here is really appreciated TIA!!!!
