This has been a periodic problem for over one year. Sometimes comes right back on , other times it won't for a day or so. We now have the TV in our bedroom, so it is no used as often. Sometimes it happens frequently, other times not for weeks. I talked to a TV repair co. last year, he said it was not an uncommon problem and t wait until tv completely died, as it was an expense repair.
You have an intermittent power supply issue. See if you can get a used one on the cheap.

The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem

Hi,
Maybe the cords have the problem.
You might have to pull and reconnect the cords and do the same basic turning on/off of the Tv.
Or you might also check the positioning of your Tv,
example : are there stereos or speakers near or beside the Tv?
it causes magnetic reaction and causes the screen to not work properly.

when it goes black then check with flashlight 2 in from screen and see if you see a picture, if so then inverter board is going out, you can google your model and inverter and find the replacement.

when tv is turned on, "please wait" is displayed. then either the screen goes black or it comes on. once you get a picture, it stays on until it decides to go out. sound still works, but no display. tv can be turned off and back on and sometimes fixes the problem until itr decides to go back off.
