Default Mitsubishi 42" widescreen will not turn on

Hello,
First let me apologize for not searching the issue here before I ask. I
can't figure out how to do it. First time here. Sorry.
We have a 42" HD 1080 series Mitsubishi widescreen. Bought it Dec 2002.
Yesterday afternoon I was watching tv for approx 30 minutes and everything
was fine. I turned the tv off and returned several hours later and went to
turn it back on. It will not turn on.
The tv has sat in the same exact spot since the delivery guys put it down
almost 4 years now. The only other issue I can think the tv had was around 4
months ago. There was a period of 2 or 3 days where the picture turned red
and the image was bent. It would happen out of nowhere. Seemed like simply
turning the tv off and back on again got it back to normal, and after those
couple days it never did it again. Not sure if that has anything to do with
what's going on now.

Thank you so much for any feedback!

It is very possible the power supply has failed, or a component on one
of the circuit boards has failed. This is not something that a non
specialized or authorized shop will be able to service for you, unless
the fault is very simple.

For these types of sets, it is best to call the factory authorised
service. They are generaly serviced by module swapping, and then
performing the poper calibrations where required.

Once again, Jerry, you are posting bull**** that is less than helpful. Why
do you persist in giving generic advice that is often dead wrong when there
are people here who have specific experience with the products.

These sets are almost never serviced by board swapping, except for
expeditious warranty repairs. He likely has a failed convergence output IC
that has the set shutting down because it pulls down one of the supply
lines. Lots of independents service these effectively, but they usually
bother to get the documentation before they try it.

If the OP will post the model number and the description of the problem
again on the Manufacturers, Service and Support forum at Home Theater Shack
http://www.hometheatershack.com, I will be happy to provide specific advice
as a tech who services lots of Mitsubishi products.

Oh dude, thank you for that much needed response. I read this stuff and
that generic "call a repairman" answer really is not worth the keystrokes
it took to reply with. True, some posters really do have no clue or
experience at all and admit this and in these cases, it is best to
recommend that they call a real repairman, but for the most part, we do
actually help each other in here with real tips and advice rather than "who
knows, maybe the power supply went bad, you should call a real repairman".
LOL!

It would have helped a lot though if the OP had posted the model number of
the set. Yeah it could be faulty convergence STK ICs but the OP did not
even specify that it was a rear projection set. It could be a DLP or LCD
for all we know. At least you replied with something that may be of some
use. ;)

Thanks guys....OP here.
Sorry I didn't give the model number. I'm home from work with a screwed up
back, the wife moved (hid ;-) the owners manual on me, and I couldn't move
the TV table to find the number behind the set...excuses, excuses, excuses.
Anyway, she helped me move the table last night. The model number on the set
is WT-42311.
It is a rear projection set.
Leonard, I'm using the link you provided. Thank you.

I don't have experience with TV repair, but since I started repairing my own
pinball machines about a year ago, I'm no longer afraid to at least check
broken stuff out for myself before I call someone in to fix it.
In December I had a problem with a 36" tv. I found a repair forum, took
pictures of my problem area, found out it was the flyback, and at least was
able to not get killed by a shady repairguy telling me this and this and
that was wrong. I was able to tell HIM what was wrong. TV works great, and I
wasn't taken advantage of.
Thank you very much for being here to help people like me!
