I have a ProScan 60" rear projection TV sold under the RCA brand name. It
has been professionally repaired once with a replacement of a "flyback"
and
a "capacitor set". It is 5 years old, and the former repairs were
performed
11 months ago. My current experience with the TV is as follows: The TV
will
work normally for about a week, and then it will stop responding to the
power button on the front control panel and the remote control. You also
do
not hear any of the telltale signs that power has been activated such as
components charging up and (I believe) a relay triggering. If you unplug
the
TV for approx. 24 hours and then plug it back in it will operate normally
for the next 1 to 7 days, then it will begin a similar cycle.
Intermittently, it will lose audio during its time of "normal" operations
(which I usually don't notice because I tend to use the TV for video
only).
I shy away from professional repair because the last professional repair
cost me over $450 and I don't think the TV is worth too much any longer.
Any
suggestions on repair (self or suggested service) are appreciated. I have
done basic circuit board soldering and de-soldering, but do not have any
skills in circuit tracing, etc



It sounds like something relatively simple, if you know what you're doing
and have a good eye, look for dry or cracked solder joints around the tuner
ground shield (not sure if Proscan PTV's suffer this but direct views
certainly do) if it still has the problem then look for the same thing on
the power supply board. If you don't know what you're doing I highly suggest
having a pro look at it, if the picture is still good when it works it
should still have some life left on it, if you poke around without knowledge
you could easily do a lot more damage.
