Hello All
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!!!!
