Celcus tv sound cutting out


Gate7, your main board in the TV may be bad and may need to be replaced. Try this RE SET procedure first, turn the TV on so you have a picture,then
while it is on unplug it. Wait 5 mins and plug it back in.

The tv keeps cutting off. I have checked to make sure that the sleep and timer is oof but the tv still keeps cutting off. it cuts off sometimes every 5 min, and sometimes every hour or two.


Hi William,
If you have necessary tools and test instruments, and know safety precaution in basic troubleshooting, I would advice you to check/replace the electrolytic capacitor in the power supply section, this cap malfunction and produce out-of-regulation which sense by the feedback circuitry and turn the unit into subsequent shutdown. Also, look for a bad solder joints on the board., it will do the same thing. Secondary reasons of symptom is Voltage Regulator IC, and microcontroller circuitry.
If you can't do the job yourself, I would advice you to look for a technician to isolate the faulty parts.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

My sony wega keeps cutting off then coming back .


a couple of years old can be a long time:

has the TV been on 24\7

It's the amount of hours that matters..

electrolytic capacitors typically last 3000 to 5000 hours....

Special "long life" caps last close to 7000
but the caps in most consumer electronics, even broadcast equipment 3-5K hours.

Is my picture tube going?


Most proj TV's of that type have 3 Picture tubes Red, Green and Blue. It's not likely that all 3 went bad at the same time in the same manner. So I believe you have a circuit problem, probably in the power supply stages, possibly a bad solder joint.

Hope that helps...
