Question about Toshiba 53H71 53 in. Rear Projection Television

1 Answer

TV rapid power cycles

I have a Toshiba 53H71 and it recently started powering on/off randomly. I described it as 'rapid', because it just clicks off then immediately back on... 'rapidly'. It is doing this every 3 or 5 or 10 minutes or so.

We recently got a Wii and it started this a day or so after we hooked it up. I thought maybe it was because of the Wii's wireless remote system. Or maybe too much amperage load on the one outlet. I disconnected the Wii and unplugged it and one more item from the power strip. Still power cycling.

I've googled everything I can think of and find no definitive answers. Anyone here have input or advice, or better yet, the solution?

I'd sincerely appreciate any help that can be offered.

Re: TV rapid power cycles

Could be power supply related or the hyper board, Toshiba p/n# 23148017... Cycling on/off is the TV's protection circuit going into shutdown to keep from causing real damage. Get it to a shop and have them estimate it.

My Toshhiba 53H71 went black and the red power light keeps blinking. Is it worth repairing.


You can repair it, it is repairable, the problem is power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hope this will helpout in solving the problem....

Turns on and off then back on then off

Discovered bulb had blown out.
At power on button, red light and green light flashed and no picture was present. I opened side panel after unplugging tv and let the bulb housing cool, then removed the bulb and discovered it had blown. Luckily I had a replacement bulb from the purchase, replaced it and it worked again.

Your Television is going into protection shutdown. More than likely the problem will be sweep related IE Convergance is the most likely culprit your best bet is to have a technician look at it
