Subject: [TechAssist] sharp ca29t729 tv. horizontal out gets too hot, all
measurements seem okay
> I have a Sharp tv that I have replaced the HOT (shorted E-C) and the new
one gets rather warm also. The B+ is about 125 (I think or 135v), I believe
the timing on the collector pulse is 10us or slightly less(reading with
Sencore SC60scope) and there is no noise on the hor signal from the driver.
I do not have a schematic and am not sure where else to look.
