Sorry for taking so long. It's been a busy summer. The polarity of the caps seem to be correct. I am going to try re-soldering them though. After looking it over again I'm not too happy with how a couple came out. I'm not the greatest solderer yet. The part # for the board is 510-1842-20. Thanks again.

I also have a problem with my power board. Watching photos of board from LP600 I think it is same board as my Infocus IN37. After changing lamp there was smoke from projector and some noise. Some part was burned. I'm asking if somebody know is it possible to change S3KB diode as I can read from it. If not is it possible to buy whole board. Thanks

Default I can repair this equipment for you if you wish

I found this forum while researching the Infocus LP600 that I am in the process of repairing, and I must say that I am most impressed at the level of technical expertise of most folks in this thread. It is extremely rare and most helpful so that I don't overlook other possible problems.

The main reason for my post is to answer those who were asking if someone could fix their equipment for them. I just happen to be an electronics engineer and software engineer at Crossway Technology. I do free estimates & my rate is $30/hour plus parts and shipping costs to & from Reedsport, Oregon, USA. If you are interested, please send me an email and I'll get touch with ya.

May Honor always know your deeds well!

Hi there!

I would like to reanimate my old infocus in32 that has the same power supply board. Could anyone tell me the power output and value of capacitors, because some of them are probably mismatched.
