Question Projector Power Supply Repair Needed

I need somebody to repair lcd & DLP projector power boards please. The LCD are for the Infocus LP690/Proxima DP6155. Most of these are working but they are pretty worn out from people leaving on the main power switch where there is no cooling fan provided. I have about 10-15 of these. They come in two parts, the DC ballast board & the AC supply board. The trouble seems to be in the AC boards only on most.
For the Infocus LP500/530 they need more work as most will not ignite a lamp at all. I have a parts list that a DIY user put out who was repairing these for me but no longer has time. I have about 20-30 of these. Usually I get more every month tyhat need repair.
Please reply to this post or email Jim at
Thank You,

Default INFOCUS SP5000 - Dead Power Supply

Hello Guys,

I have an infocus sp5000 and it stopped working all of a sudden. I believe the PS is malfunctioning. I performed some test and cannot find the problem. Can anybody give me a hand? What are the voltages at P2? That is the connector that goes to the motherboard.
