Question about Panasonic PT-47WX53 47" Rear Projection HDTV
You may have a problem with your flyback transformer, I would suggest that you perform a ring test to see if any of your windings on the flyback are shorted. In addition You may want to also check the input to the Horizontal Output Transistor, to see if the driver pulses are of the proper amplitude. Besides these two things the only other issue colud the the high voltage trippler (if this is not part of the flyback). Check these things, you will need the following equipment:
2) voltmeter (multimeter set to DC volts)
3) High Voltage probe
4) A test set that can perform a ring test (My shop uses the Sencore LC102)
Or what you can do is take the flyback out and take it to a TV shop and for a small fee they can run the test for you, (My shop usually charges $20.00 - $30.00 for this
I hope this helps
