I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

Replace the convergance ics.

Your tv might have a defective power supply, and/or convergence circuit. The initial cause of the problem, if it is the convergence circuit, is usualy a loose conection on one or two jumpers close to the convergence output circuits (STK392-1110), in with case this chips might need to be replaced and a pico fuse of 5A on the power supply too. I hope this help you.

You need to replace the convergance IC's

It can be the plastic anti polarizing screen that covers the display.

Often it causes grey or red shadows on top of the picture.

There are 2 large IC's in your set and one of them has burned out. These are called convergence output IC's and are usually the STK392-010's. A good idea would be to go ahead and replace both with the newer, upgraded STK392-150 IC's. A good tech can change those IC's in about an hour and a half, and when I do a housecall for a set like that I charge $150, but shops in your area will vary so be sure to ask around.

dJbsharp1: Check if the cleaner you use discolor or remove the clear of the screen. Touch the cleaned part and somewhere else on the screen to see if is rougher than the part you didn't clean-up. If this did not occur you can clean it up completely and watch the difference. If it's rough as I described you, a replacement will be necessary. It is easy to replace. Very easy.

How old is the TV? Does it have a marketplace of apps that came preloaded? Is there a search button in that screen? If so search for the app, you can also search for Amazon prime Video App that comes with Hulu.

Sounds like some thing short circuit at its circuit board. Short circuit protection activates, as the set is switched on. Contact any service technician to check and find out the fault. This is not a user repairable fault. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ https://elektrotricks.blogspot.com/ faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent. Search the site by type in the brand name and model of your set, in its search bar at the right side column, and press enter.
