Hi members,
The blue convergence is off about 2 inches at the top left corner of the
screen.
All convergence adjustments work properly, but, have no effect in this area.
I found some info in some e-mails I saved, saying that the DCU module might
have bad fish-caps in it. I pulled the DCU module to the shop, where I
examined it, and could not see any discolored, or any signs of leaking caps,
or contamination. I hate to pull, and replace any of these caps, unless I am
fairly sure that is where my problem is.
I have not changed any of the 3 convergence ICs yet (STK4274), cause I would
have to order some in first. What should I do first ? Change the convergence
output ICs, or rebuild the DCU model ? There are about 20 fish caps on the
module, and they are hard to remove without damage to the traces. This set
is 9 years old.
Any advice is appreciated.
