Re: Samsung LE32B530P7WXXU No Power

try unplugging the cable from the power supply to the main board, see if the backlights come on, not sure if you described weather they come on or not.

Didn't make a difference, Still no DC voltage output, Also tried jumping the 5v power on pin to GND but still no luck,

Here is a clearer picture,

Check all those components in the red.
Check the Voltage on VCC (PIN4) and the Ground pin 5 of ICM801.
Check the Voltage on Drain PIN 1 and the Ground pin 5 of ICM801.
Check the resistance reading between Ground pin 5 against all the pins of ICM801.
Right now you need to get STBY power supply working first.
You will be working in the HOT DEADLY side of the circuit so you plug your TV into GFCI outlet and do not touch any thing on the board with your hands.
BTW, ti turn on the main power supply you will have to feed the PS_ON pin with 3VDC, but right now the STBY power supply is not working so it will be useless right now to turn on the main power supply.

This thread can now be closed, Fault turned out to be a crack on the board which passed through a main trace, also 2 of the tabs which supply power to the inverter had broken off inside the inverter connection, removed both tabs and bought new board from ebay, tv now working. ;-)
