My tv shuts off after about 30 minutes the first time I turn the tv on for the day and about 5 minutes after that. What could be the problem. Is it a lamp or ballast board and how do I confirm which one is bad.

I had the tv on for 2 days this time before it shut off. Can it still be the lamp or is it something else. Please help.

ok so what you are saying is it still may be the lamp. I should replace the lamp and see what happens first.

Pull the lamp out and have a look at it. I have a tutorial published on projection lamps in my Tips & Tricks. Have a look at it, there's a lot a information in it and towards the end of the tutorial you will find some explanation of failures and what to look for. I hope this was helpful, best wishes.

No, the lamp has a burner gap. If it has grown out of tolerance, it will become too large for the lamp to stay lite after it gets hot. When it comes back on shortly after it shuts down, it will stay on for a few moments then go back off. The length of time can vary... depends on the ambient temperature in the room... now that I said that, you may be thinking of pointing a fan at the back of the TV... don't. That creates a positive pressure within the TV... heat doen't get out.

RCA D52W20 TV powers on fine, then shuts itself off after 5 - 10 minutes. After 20-30 minutes, I can turn tv back on, but then shuts off again in 5 minutes.

it looks like the problem is in the 16v line..try to take it apart..and there's gonna be a 2200mf cap leaky.

I turn on tv shuts off after 30-45min. red lite goes dim

It's likely that the TV will require service since your troubleshooting steps didn't resolve the problem. If your TV is smaller than 30", you may carry it in to the retailer of purchase for repairs. Otherwise, service for your TV can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

My Magnavox digital converter box shuts itself off every 5 minute

Check that you have not got an auto power off setting on. Check that the aerial connections are good. That the signal is strong from the stations it is picking up. Weak signals can cause the box to shut down.
It the box is very hot when it shuts down, you might have a fault on it.
