I have this Magnavox 20" TV and when you turn on the TV there is a black screen - no picture, no sound. In fact there is very little indication that the set is turn on - maybe a slight click. Took off the back - fuse is not blown. Any ideas on what to do next, what to check for or where I can find a schematic? One of the electrical techs here at work thinks it might be one of the transistors but won't look at the TV without a schematic. The set is a little over 1 year old so it is beyond its warranty period.

I appreciate any insight you can give me!!

Check your horrizontal output transistor, flyback transformer, low voltage
fuse in the power supply. The horrizontal output transistors are the
most frequent cause of high voltage shutdown- dead set or mabe just the
led that tells you the set is on.

Can you give me some insight as to where these components are located? I tried Sam's PhotoFacts and cannot find the schematic.

Also, the low voltage fuse checked out okay - that was the first item I tried to find and locate since it would be the "easiest fix".

Thanks
