Have Baird X342DTV stuck in standby (blue light)

Uses-: Phihong -  PS22-417-R power board
          Main board-  PY12038 Hair 2006
       
Changed all caps on psu... wondering if there's a firmware flash anywhere, can't seem to find any.
5V supply is good, nothing on the 24V inverter rail and about 3.2 on the 12V rail, not having any circuits I guess this might be from the s/by supply.

The power supply powers up minus backlight when supplying the 'power on' voltage

Worth trying a new eeprom dy'a think?

Problem with inverter board

Davy:
Thanks Jordan, you're a gem.

We'll dig him out and have a look... thought they gave error goods.

Davy:
Inverters OK..!

I can 'force' the main power supply ON along with the inverter , backlights are OK.

There is one hiccup on the main board that nearly foxed me a 1501-50 switching regulator, it was marked 12V on the output on the pcb  test point, seeing three electrolytic's on the line was rated at 25Vdc I thought 'Eureka'.... but the 1501-50 is only a 5 Volt regulator looking at the data sheet, just my luck the voltage was 5.09V.

Thank you for trying though.
