Hi my alba lcd 32880H DF tv wont turn on,stanby light flashing blue and red, if left unpluged for a while it will work fine for hours before it shuts off and flashes ,no visible signs of bulging caps, unpluging the mainboard from the psu board while turned on and pluggin straight back in also cures it for varing amounts of time but doent really tell me which board is at fault. The psu board is a 17pw26-4 and the mainboard is a 17mb45m-2 any ideas please.
