Hi!

It sounds like you have a power supply problem! You will probably find some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). As far as the noise problem this could be caused by harmonics, from the bad caps!

Sound but no picture, can change channels, red flashing light on power supply board. Please help.


The problem is likely with the screen itself. The power supply usually supplies both screen and speakers and has a light flashing on it indicating that it has power. Screens are often not worth replacing unless under warranty as they can sometimes cost as much as new TV to replace.

I would actually not recommend opening the TV since you could get an electrical shock. I can suggest you to unplug the TV for a while (30 minutes) and then just plug it back in and turn it on. If that does not work, my recommendation for you is to take the TV to a local repair shop. It may be a fuse or internal component shorted out, but in this case is better to have a technician check the unit.

Check the power supply module for bad DC filter caps first, then check the backlight inverter board for shorts.
