Hello.
I've worked most on Plasma sets and have some questions about LCD technology. I've got a LAVA 32" LCD which doesn't start the backlight.
The powersupply seems to operate correct. The output voltages is within limits. I've gone through various voltage regulators on the mainboard, without finding anything abnormal. The inverter board gets an ON signal from the mainboard.
But then I don't know what goes wrong.
I don't know the level of high voltage generated by the inverter board, I can only measure up to 1500V with my oscilloscope.
I'm looking for general troubleshooting advice.
