Hello. I am working on a Sanyo DS27910 with chassis 27910-01 made in 2002.
I have sound but no picture except for a glow that appears to have video in
it on the left side of the screen. I have 30KV HV, +150vdc with 140v p/p of
video on the CRT cathodes. The filaments appear normal. There is a
ticking sound from the CRT even though the HV is normal. I unplugged the
DAF board but did not help. I am thinking the picture is way off center to
the left. Has anyone seen this before? Does someone have the exact
schematic? (the one I have shows only 1 transistor and 2 FETs on the DAF
board).
