LA26B450 - N66D Chassis
BN44-00259A power/inverter board.
Unit does not power up.
If I unplug the logic board, the backlight turns on.
Checked the voltages at the powerboard connector and they all seem slightly too low which is I suspect is the issue. eg (5v rail is measuring around 4.7v. 13v rail is measuring about 12.7)
Caps look ok
I have the schematic, but cant seem to decyper the various parts. They definatly not as good as the sony diagrams I have used in the past.
Not sure where to look, but suspect around the regulating area, so any assistance is appreciated.
Thanks
