My T.V will suddenly turn off. The volume gets really loud and it just shuts off and we have to keep turning the main power on and off until it decides to stay on again. It gets quite frustrating trying to watch TV at night. Do you know what would be causing it to do this? It seems to us there there is a short or a loose wire or something that may be causing it.

I have been repairing Plasma Tvs for some 3 years now and have found most of the problems caused are by Capacitors.Once again Soniq are no different to the others.The fault is on the main Video Control Pcb.Replace Capacitor C529 which is a 470mfd25v.This cap is mounted next to an inductor coil at the top middle of the pcb.This Pcb is the one which has the tuner and all inputs on it.
Good Luck AND PASS THE WORD AROUND. LET US KEEP THE SERVICE INDUSTRY GOING.
the rca itc222 is what i like to call a value set walmart sold a whole lot of these because usally it was the best price set. The thing with theses set are that the processor in these set shut these down if it detects a problem to keep from starting a fire or cause more damage. since it cycles then you no it just not a fuse or something simple. generally it comes down to a high voltage problem. horizontal ouput transistor or a flyback. there have been reports of bad capacitors in the power supply cp150 is one. in general average repair runs 250 to 400 in the shop i work for. depending on the problem if you have a bad crt and it is not under warrenty then repair of set turns into not really worth it. always unplug the set and leave unplug for 30 minutes this reset the processor(i have never seen this fix the problem but it is the first thing the customer can do. also notice any sounds smells coming from back of set
This is a Polaroid brand.
The failure on these TV sets is originating from the power supply assembly not providing a clean DC voltage to the main board.
The power supply will need to be repair since there aren't service parts available.
I could fix the power supply for you.
Send me an email to email@example.com for more info.
sounds like the high voltage transformer or could be high voltage off the tubes.
not a good idea to keep this running as it will cause more damage, best to have service tech look at this since it's high voltage.
Be careful. This same problem burned a mark in the Blue crt on my
pro730HD. Three months and the Service Tech and Pioneer have been
unable to determine the cause (they claim). In the process they have
blown two more crt's.
When your tv goes off, try turning it back on using the main power
button instead of the remote. The button should be behind a flip-down
strip below the screen. When it is working again, look for any faint
colored spots in the picture most prominent on light backgrounds. Mine
is a yellow Y in the center of the screen.
If there are no spots, I would suggest you don't use the TV until you
get it fixed because eventually it will damage your crt ($750). Of
course, as I said, they have been unable to fix my problem and I have
had no TV for three months.
