I have a Philips 23PF5320/28, and it appears that it is not getting power to the unit. The cord is good and so is the fuse on the power supply board.
I pulled out the power supply board and it has a burn mark near a resistor (marked 3081, and a diode (marked 6068). The burn mark is between those 2 componants. Is there a way I can tell what the values of the resistor and diode are based on the componant numbers printed on the board? If I replace those 2 componants do you think it will fix it? or is there some other underlying problem?

Thanks In Advance
John

Compare location numbers to same numbers in the parts list and on the schematic in this service literature. Cool

3081 212010500027 RST MOX 1W RSS A 0R15 PM1 A (.15 ohm 1 watt)
6068 ? Can't find listed other than as part of other part numbers.

Thanks for the reply.
I removed the resistor and it is definately burned.
Do you think that something else may have caused that resistor to blow?
I looked on the schematic and there is a FET upstream of that,
(part # 7062 - STP10NK80Z)
should I replace that as well?

Thanks

Check it for shorts. Diodes as well.
