Does the audio still work normally? If so uits most likely the inverter board which has failed and you can get a replacement inverter from www.tvcircuitboards.com

SOURCE: won't turn on

These units have a separate switching power supply that does indeed get very hot. What I have found is that a 1000mF@25v capacitor goes bad in the power supply and needs to be replaced. If your set's red power light turns green for just a second and then turns back to red without the set turning on, this may very well be your problem. You can either try to find another power supply (make sure it's rated at 12v-5amp) or take your old one to a repair shop. Be very careful if you decide to try a repair yourself, switching power supplies can pack quite a punch.

SOURCE: green power light comes on for a split second, then red.

The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories

How do i fix a proscan tv to turn, only a red and blue light are on


Well without actually opening it up and determining where the problem is, it's unlikely you will get it to come back on. I suspect something wrong with the power supply but it could be something else also.

Screen black


Here's the test to determine which board is faulty. With the TV on, as usual, shine a flashlight on the screen to see if there is a faint picture. If there is, then the ballast board for the backlights is bad. If there is no visible picture, then the T-Con board is bad.
