You sure your voltages are good? VGL?

Yes, VGH 30V and VGL -7,5V, problem to screen i think.

There are several other voltages that need to be there.

At all measuring points which are marked the voltage is correct. I can't find the wiring diagram for t con Grunding 40 VLE 6142 C.

Only other suggestion is make sure you have those voltages on the tabs on side of screen.

Did you think to check the voltage on cof.
