Had a problem before with the convergence, removed and blew out the dust on the DC board reseated and it was fine, had another issue with the Vert focus board, same fix. Now the error 30 came back and got another dc board, put it in and still get error 30, any ideas?

Are you SURE the second board was OK? DC board failure is common. IT could also be a power supply I'm guessing. Those drive the DC board.

I have a theory thast sony built the most unreliable projectors ever.
 At any rate, it appear that "blowing the dust" out isn't going to fix your machine. since the problem is intermittent and randomly pops up I think it's also power supply related. The power supply section is known to be troublesome on these, as well as every other board in there.

The board came from DraganM so it should be good, what should I check on the power supply to narrow it down? The dust was in the cooling fins so I believed that the heat would build up and cause the issues I saw. Error 30 says abnormality in the power line of the dc board, what should I check and for what voltage? Thanks.

there's nothing to check AFAIK. The one time I had a power supply board go bad it blew a capacitor on the GB board and spot burned the tubes. You should send the entire power supply section to curt and have him test the boards and then repair /replace the bad one.
