Re: 1-second to black 22" LCD need guidance
Noticed it changed behavior a bit with the two 10pF capacitors, maybe connection was not great, after POWER off, the GREEN light would not stay, it turned to RED light, i.e. completely OFF, power...

The question up-front:
Is it safe/OK to replace a ceramic capacitor marked "5J 3KV" (which I assume is a 5pF, with a 10J 3KV, which i assume is 10pF.. I know the general rule in...

Re: Repair Fence Energizer SS-1000E Fi-Shock
OK, took some time to test/measure, all tests were done without Load/COIL as follows:
Test1: Pull 400v/16uF large capacitor OFF circuit (pull cable) and energize the board. that came OK, no heat...

It may take a few days to get time to...
