Question about RCA F36450 36" TV

1 Answer

Rca f36450 am working on a set for a friend, that also was working one night, and wouldn't come on the next day. i bought a photofact for it, and so far, the only things that i see are resistor RF09 (14V SUPPLY) has been hot but ohms ok out of circuit, but this supply only tries to come up to about 10v cap CL20 (680uf0 reads 660) but seems to hold a charge ok my 210v supply stays at 130v but the other outputs of the flyback seem normal (with flyback input signal)

Picture blurry


What was replaced by the repair shop? The blurriness may be out of focus. If so, the focus is controled by the flyback transformer. That connects to the picture tube at the top (anode cap).
