Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: TV was playing, then the screen turned black.

If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

SOURCE: Soyo 32" won't turn on

The problem is the capacitors on the power supply board. There are two of them, the rating is 220uf - 250v - 105C (M). The back side of the capacitor says V9A PET. You need to remove the board, make sure the capacitor is drained, (you can do this by placing a screwdriver across the posts) Use a soldering iron and remove the capacitors. The only place that has replacement parts is at www.mouser.com, Install them, make sure the polarity is correct, re-solder them back into place. Re-connect the board and it should power back up correctly. Good Luck. Steve

Sounds like your resolution on your computer is set too high for your tv to accept. Try putting your computer resolution down to 1024x768 or lower and see if that works.

Most likely your power supply is shot. That is the most common problem with tvs'. EIther power supply or convergance board. If tv won't stay on, then it's a bad power supply

Proscan 32" LED TV. Picture colors are opposite of correct, mostly reds and yellow. Any movement on screen shows multiple images. Refresh is slow or not working.


The TCON board or the LCD panel is faulty. Can confirm by replacing the TCON board.

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.
