Looking for repair ideas on a projection TV.

Guest
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.

I would check the power supply for the entire unit. Soft on
switches and standby start-up circuitry keeps this power supply up,
and the only thing that changes on start up is the loading. If it
fails, and then requires a rest before working again, it sounds like
dried out electrolytics on the supply or perhaps the IR/soft on
circuitry. Electrolytics are always the first thing I check out on
older power supplies. I know that 5 years isn't very old, but there
have been some bad batches made over the years. I recall a
motherboard recall at one point where the electrolytics had bad paste
mixes in them.

Anyway, that is a likely culprit. Another might be enough dust on a
part that it doesn't give up its heat well, and eventually runs away.

Be careful of the anode leads on those guns. Projection sets have
some mean juice there.

Another alternative is to bypass the soft start altogether, and use
a hard switch on the unit. Some of the convenience takes a hike, but
it makes it a working unit again. Must fully power down (unplug) to
save juice in the interim times though.

Now I just knew that if only we could all be sufficiently patient, you (Dark
Matter) would and could rise to the occasion with a coherent answer
somewhere above the crude monosyllabic responses for which you have become
infamous. Keep up the good work; there may yet be a place for you in the
family homo erectus.
 
Sure would be nice if instead of kind works you would use pay pal to
compensate for the info. Duh

Stated many times before is the fact that you get what you pay for in life.
You for shovelling sludge, others for taking the deligence to learn how to

However, in your case, well enuf said!!

You're a cowardly little blowhard, a Chihuahua with a tiny little bark,
yipping incessantly and soiling himself from nervous incontinence. Your
daddy should have pulled out and shot you against the side of the dumpster
your mommy was leaning up against when you were conceived. The sight of
your old man's jizz running down the side of a trash can onto the filthy
floor of a back alley has a kind of poetry about it, unlike the shambling
waste of oxygen-stealing flotsam that you've grown up to be, you complete

In short, I hope and pray a lightning bolt of a size to make Nikola Tesla
drool, turns your doublewide into something resembling a microwaved
Faberge egg, you moronic, slack-jawed cretin.

Please FOAD at your earliest convenience.

Watch the language, pootie pie. I know you have trouble with English, but
the repeated beatings you've been begging for (and receiving, quite
enthusiastically) are a good motivational tool for misanthropic
microencephalic Future Organ Donors of America such as yourself. But,
only if you pay attention to the lessons pounded into you by your moral
and intellectual superiors. That's damn near everyone who has access to a
computer keyboard, making your vetting process simple enough for even you
to complete with a low rate of false positives.
