finger to keyboard and composed:

Came in dead with no click. Replaced shorted HOUT but it blew instantly
at turn on. Then replaced fly & HOUT but then only got the relay
clicking 3 times. Came across a sym/cure about horizontal being out of
phase because of a corrupted eprom so I tried jumping C4402 with an
identical .015 cap and now the set does turn on with a good picture
(except of course for the bending pincushion effect because of the
jumped caps). I tried a new eprom but still have the same problem. So
the current status is that it powers up when C4402 is jumped but it
doesn't power up when not jumped and a new eprom didn't solve the
problem. Any suggestions are greatly appreciated. Thanks, Mark

Is C4402 the tuning cap, ie is it connected to the collector of the
HOT? If so, and if this cap is open or low in value, then the voltage
on the collector is probably rising high enough to trigger the set
into protection mode. This voltage may also exceed the Vce rating of
the HOT.
