M # P52755BA Ch # CTC178L2B, pix not quite wide enough, & slightly
keystoned, found
a bad connection @ CR401 in pincushion circuit, replaced it, found
Q801 leaky (IRF730), replaced it, R801 is burnt, but ok C4402 is ok
(0.94 uf @ 250 volt.), I think U4801 is bad.
It's an LM311N. R4307 in the 26 volt line gets hot, & is dropping
about 9 volts across it.
Have any repair tips, on this unit? Dani.
