Re: Toshiba 37" inverter board failure
OK, since we do have backlights, then the 24VDC power supply is working, this 24VDC is fed to the IC QE90 through the device GR90. Try to locate that device, one end should be connected to pin 2 of the IC, the other end should be connected to the 24VDC pin of the connector to goes to the inverter board.
