Could find no info on this model so in the dark as usual. Stuck in standby, no response at all, check IC801 on top left of mainboard for 3.3V output, if none check for short on output, presuming there's a 5V input! Short traced to C2025 below(print side) IC300 (sm cap), replaced with standard 0.01uF as value unknown, powered up and worked with no problems.
