[TechAssist] Re: Need scan of Vertical Circuit - Mitsubishi CS-31303

is the 12v supply to pin 1 of the vertical Ic (LA7838) working? on some 
Mitsubishi's a set of bad connections devleop off a SW-mode transformer in 
the power supply. Of course the glue could have eaten thru the traces 
somewere along the drive path too..

Mitsubishi CS-31303 Chassis JU-0

No vertical deflection.
Replaced R570, caps C986, C449, C987, and the vertical output.
Still no go.

A scan of this circuit would be helpful.
Thanks,
