Hello,

The reason you have sound and no picture is because there is a problem in the unit. The problem most likely can be the lamp, the t-com board or as capacitor on the main board of the television.

First, check the lamp, if it is not burnt or leaking, then check all the capacitors on the main board, if none of these seem to be the problem then replace the t-com board.

Unplug the television for some time, lets say about an hour or two so the high voltage on it will dissipate. If you are not familiar with this kind of technical activity, then seek the assistance of a professional repairman. Also check the warranty period of the television, to know if you can take it back to the dealer that supplied it to you for further assistance.

Take care and good luck

42 inch flat screen shows black screen with sound only no picture


That sounds like the backlight system or its powersupply has failed. If you can see an ghost like image when close and at an angle near the dge (depends on the light) then this confirms the backlight being the problem.

Repair cost should be about $100. You should be able to get this fixed under warrenty if you have any. If not get repair estimates before doing anything. It should be worth fixing but it never hurts to know if it is getting close to what a new replacment tv is worth.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.
