The board is just dead, getting power to it but nothing coming out

ok that may well be repairable

there are 2 or 3 capacitors on the board

look at the rated voltage

one will be 400V. you can power the board and check for voltage on that cap. it should be 320v or so DC

if thats ok check the other caps. these have lower voltages 5 to 20v DC or so

if you dont get the 400v look for a fusible resistor to see if its gone. also look closely at the power chip, its a 7 leg chip look for a small blemish the size if pin head on the top surface, normally shiny. I get that mark if the chip overheats inside and goes faulty

if you get the 400v but nothing on the output caps its most likely the chip. if you get a voltage on the output caps that seems to rise then dies then there is a problem somewhere else on the board and it needs changing

cant find a decent pic of the board components to point thins out to you

if you can solder its a cheap fix if it works. aswo stocks some chips otherwise its ebay. dont know the chip no on this board but they often begin LNK or TNY
