Hi, please see attached picture. This came from my electric heater. The lcd display doesn't come on. The 110VAC is available and goes into the board you see and out to another board to convert to 5 and 12 vdc which gets wired back to the mainboard in picture. So I see the 5 and 12vdc and 110vac available on the mainboard, but the lcd doesn't light up and the nothing is ON. Any suggestion where to check? For lack of better knowledge I tend to first blame the caps, could these big yellow square caps (3 in the picture) be faulty? They read 0.1uF 275VAC.. Thanks
