Question about Polaroid Televison & Video
SOURCE: Polaroid 15
Do you have to turn it back on with the remote after this?
If so, then you may have set a timer by accident through the menu system.
More information would be required.

Sir the problem of your tv has two possibility, the inverter board may be damage or there is no supply to the inverter board. To check the voltage input on your inverter board you should remove the back cover of your tv, the supply input is 24 volts dc. If you can do this let me know.

If you can see a picture (dim and low contrast) when you shine a light on the screen from an angle, your backlight inverter may have a burned-out part.
After this test, whichever result you get, unplug the set and use your eyes and nose to search for overheated parts. I have found connectors that overheated because of a poor-quality solder connection on the circuit board. Note that parts, particularly resistors, can overheat because of a fault in another part.
It is common for solder connections to deteriorate if they are frequently run at high temperatures. Sometimes circuit boards "normally" turn brown from heat because of marginal thermal design. Check the solder connections on components in the hot areas.
Static electricity precaution: most digital electronics are easily damaged by static electricity discharge. Avoid touching the metal parts of the circuitry unless you first touch the metal frame of the set to discharge any voltage buildup on your body.
