Folks when ordering boards or parts make sure to look at the stickers on the board

they will give your revision.  The board can have the same exact part number but the revision is different.  I.e. Firmware updates.  I had to learn the hard way.

One way to see if the power board is bad check the standby voltage 5vdc +- 1.5

if it’s not correct then it’s most likely bad.  And a good visual inspection of the capacitors on the power board are swollen those are bad.
