I have a rca d52w23 while i was watching tv in shut off and there was like a smoke smell I mean I turn it on and it shuts off by it self is it worth fixing it and what can cause this problem


Where there is smoke something burned--unplug set for safety and if curious open rear cover and look at boards near rear of set for a burnt part--that will usually determine if worth fixing or not.

Hey bbendure, I have a similar/same same problem! My model is a GV42L.
It has a blue screen that says no signal t, then it turns itself off in about 20 seconds.
Is this the same problem you see?

Green Screen, No Sound, Shuts off after 10 seconds


Almost certainly the green picture tube is shorted. This is a very expensive repair; probably not worth doing.

I have a panasonic dimension 4 turbo bake microwave model nn-a774sbbpq when switching on it runs for approx. 20 seconds and shuts off this time factor is always the same any ideas?


The uPC system is sensing a failure of some type. This could be that the magnetron is not emitting to specificaitions, or one of the power supplies are not operating in specs.

This is not something you can fix yourself. You will have to take the microwave oven to a service center to have an estimate for repair. If the unit is out of warranty, it may not be worth to service.

In case you get curious, I would never suggest for you to open the encosure of a microwave oven. There are very serious safety issues with working in this type of appliance.

Philips 46pp9302 about 5-6 yrs old after 20-30 min. shuts off


Just posted this elsewhere:

Is the cooling fan running?

If not, the set may be designed to shut down after a few seconds to protect itself (and you).

Sony KV 20S40 20" tv flutters, reduces in size and then shuts off


The set most probably has cracked solder joints in one of the deflection circuits, which is pretty common. The picture tube and major components are fine. A good tech can quickly resolder the main board and that should not cost too much. If your set came into my shop I would charge about $50 but ask around, the shops in your area will vary.

TV does not turn on


You have a short in your unit somewhere or a high voltage problem. The most common problem would be a high voltage failure. If you are not familiar with televisions and their safety this is best left to a repair shop. There is not much in a TV that consumers, unfamiliar with the system, can check. The problem should not cost too much to fix. Check for a shop which has a free estimate or low estimate which will be subtracted from the cost of the repair if you choose to have the unit repaired there. Good luck.
