So you are not going to show us the schematic and the board? That is what I thought, just more BS from you.

Re: LG Flatron W2343T-PF Invertor Transformer Getting Hot

It can be due to worn out CCFL so they draw too much current, you can try reducing the backlights level.

Re: Sennheiser Ew100/G2 Wireless Mic Receiver

OK then since you are are able to test those test point on page 14 as I asked before in my post #10, then just use the same test points you did per page 14 but check the resistance this time instead.

Re: Need help with resistor value please

1) Again, I still like to know what the P/N as printed on the body of that diode.

2) Remove that diode and test it in both directions in using Ohm mode.

3) Look at the P/N as printed on the PFC...
