TV turns itself off then back on

I have a Hitachi Ultravision LCD tv and it has started turning itself off after e few minutes. The only light blinking when it cuts off is the power light then after a little while it turns itself back on. Can you tell me what may be the problem and will it be expensive to fix?

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
Capacitors are very inexpensive but require some soldering skills to repair.

Hope this helps

Hitachi UltraVision Tv Keeps turning off. The lamp LED blinks. Both light engine and lamp are new.


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

Sounds like you have something in the wrong setting that won't allow the signal to get through. If the video 1 line works OK but regular input will not work, that is almost certainly the problem. I would try just unplugging it (turning it off is not the same thing), let it reset for a few minutes; then plug it back up and see if it will reset by itself. hope this helps.

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!
