Is the main fuse blown?
If yes, there's a problem in the primairy side of the power supply.
If no, check the following:
1) Do you have 300/160V over the main capacitor.
2) Is the primairy-power-transitor "working"?

we have two kinds of power supply inside your tv 1. low voltage power supply 2. high voltage power supply........
check the load first or high voltage power supply.... use variac transformer... then if the picture tube loads you have a good high voltage power supply...... then focus on the low voltage area.... thanks I hope this helps.....  |
