Hello gabed,

 

The problem may be in your switching power supply or in your high voltage power supply, I would suggest that if you have a background in electronics you do the following.

 

1) look for any blown fuses and replace them

2) Using a schematic measure the incoming AC voltage and the DC levels on the output of the switching power supply.

3) remove power from the set and take resistance measurements to determine if there is a short circuit anywhere in the DC path.

4) Measure for shorts and opens in the High Voltage section of the set.

 

These are the usual checks you will have to do.

 

Now if you don't have a background in electronics, I would suggest that you have a qualified TV technician come over and check your TV set.

 

I hope this helps,

Thank You,

Shuttle83
