    Does anyone have a good modification for these Bush PSU's .

    I have replace the capacitors etc in a number of these sets with higher voltage , high temp caps but they sometimes only last 4-6 months.

    surely someone has found a way to modify the boards to get rid of this problem completely.

Hitachi rear projection TV clicks when you turn it on, no picture

No schematic, major short, usually the power supply or high voltage circuit, nothing you yourself can do. Pro repair about $450.00. If your in electronics replace the HV transistor first.. then??

The problem you have is with the G1 board. The 17 volts is not supplied. Do you have a multimeter and know how to trouble shott following a service manual schematic? if not call a pro to assist you as this could be the G1 board, but to be sure, you will need to troubleshoot and check some voltages and follow circuit flow using a schematic diagram.If you can then let me know..
