BN44-00192A...Repaired..now has other fault

[scooby-doo]

Hi

Just repaired a board BN44-00192A, it kept blowing fuses, found the diode (DP801) was open...as a matter of precaution I changed the bridge, the fet (QP801S) and Diode (DP802)..

I also changed the 450v/150f Cap, replaced it with a 450v/170f as this is all that was available

Now the fuse isnt blowing anymore but the standby light is just flashing.

Anyone any ideas
