I have to unplug tv several times and turn on each time and then it stays on

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

Here is the fix:

This player should be charged up until the green light goes out to be fully charged. I usually leave them on over night.

I left if off and unplugged for a few hours. When I plugged it in it started working again. My recommendation if this happens to you is to just unplug it all and let it stand for at least 4 hours and then plug it back in.

Good Luck

when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.
