52" RCA CTC178 Pincushion trouble.
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), put an IRF630 in place of it, now the pix is waaay too narrow on width, with more keystone. R801 is burnt, & don't know the value. C407 is ok (0.94 uf @ 250 volt.), Anyone have a schematic for this unit? Or have any repair tips? Thanks, Dani. |
