Check and replace all the electrolytic capacitors at its main power regulator board and check. If it do not help you, replace the power board as card basis. It is a power regulator board problem.

I have a sansui 19" LCD TV+DVD
I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there.
The set is not yet 2 years old.

Aquos has the same problem. I'm not sure how I discovered this, but
when I lean the TV forward and hit the power button it will turn on
every time. If the screen blacks out and I don't lean it forward when I
hit the power button, the screen will just remain blank. It is very
weird, but at least repeatable.
- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

I am going to assume that you have not already found the answer to this problem. It is actually pretty common for flat panel televisions in the winter to be too cold to turn on. What I did when faced with this problem on my 32 inch memorex was turn it on for 30 minutes while covered with a fleece blanket, than turn it off. When you turn it back on it should work...did for me!

Hi. You can try to go into service mode and reset the LCDTV to Factory Default. This will clear out all buffer over run's and any software related issues. It may fix the problem or it may not. If this doesnt fix the problem than you need to have a qualified Technician to look at it. The problem is in the AV circuit board, a technician who is qualified to repair electronics at circuit board level should be able to repair this problem rather quickly and inexpensively. Most technicians who do not have the expertise in repairing cicuit boards to component level would rather replace the whole AV board than repair it and this will be rather expensive.So talk to the repair shop before you drop the TV off.
Be very careful when accessing service mode. I suggest to write down all information in all areas before proceeding to a factory reset. If you do not record all values correclty you run the chance of not being able to use the TV again. To go into Factory Service mode, use the original remote and in this sequence push POWER OFF-MUTE-1-8-2-Power ON, the set will turn on and enter service mode, if you hit all previous keys correctly. If it doesnt try again. When you are done hit POWER OFF and this will exit service mode and save the data.

You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.
