Thanks for the update. Just to make sure I'm getting this right. In theory, all that would need to be replaced is Qs801 and the Qs802. Thanks for your time.
Our Samsung TV LNT4053HX/XAA is having the same problem with the on/off power switch it clicks about 12 times before turning on. Thanks for the insight!

ReplyDeleteNo, for this particular repair QS801, QS802, F803, DS801 and DS802 were all bad and needed to be replaced.

ReplyDeleteCan you explain how to test DS801/DS802?
ReplyDeleteI have a Samsung PS50Q91HD that has a similar power board.
I have QS801/802 shorted and F803 blown - I'm just not certain how to test DS801/802
