Mitsubishi Diva CT-33AC2SL dead and clicking

Truly ancient but good tech. I have a 1994 Mitsubishi Diva on swivel base, trouble free until now. Sentmentally attached to it, the problem has exhibited and slowly become worse over the last few months until now it is "dead and clicking".

The picture over the last few months has occasionally just turned off, but a little tap with a closed fist in the sweet spot on the side has turned it back on. The problem has become worse, until the wife called me at work yesterday and said it is dead and a loud clicking noise is coming from the chassis (left hand side, where I had been tapping it) and the standby light was clicking on and off, trying to turn on.

Alas, cannot get it to work now. CLicking noise, and standby red light clicking on and off, on and off.

Could it be the electrolytic capacitors? Anyone got any suggestions on what it could be? It is fairly old, but we love the picture and may get it fixed instead of leaping into the new tech (plasma or lcd).

Thanks

Lino

Check for solder joints you may have beaten loose.

Sounds like it had a cold solder joint which would have been a quick easy fix, but you continued to use it until the bad connection blew out the HOT or other power semiconductor and now it will be considerably more work to repair. A tech can still fix it for you without too much work, but it would have been probably 1/4 the cost if you'd taken it in when it first started to act up.

Could be the flyback shorting.

Right. So why the intermittent clicking and flashing of the indicator?

Well life's a learning experience all the way. What do you mean "bad connection"? Solder loosened, clip joint or friction connector loose? It is on the board in that area do you think, or a module like the power supply? I wonder if anyone has the manual for the unit or how to get it?

Np. If it is the flyback, you should be able to take off the back and hear it clicking, as well as see it arcing if it can build up enough charge before shorting. Could be something else too...

I've read that if a flyback goes, it can take out the HOT too... So fixing it may be a very YMMV deal.

Went and bought a Panasonic 106cm Viera, waiting on delivery right now. Will give the Mitsi to my daughter if she wants to fix it. Can I ask, what is "YMMV"?
