After researching a little online, I've read about the possibility that the "Ballast PWB" could be the culprit in my situation. Apparently, this part can blow out with the lamp. I'm no expert, but this sounds reasonable considering it is the part that the lamp plugs directly into. If anyone has any input or knowledge about this part, it would be much appreciated.

Also, Does anyone have experience replacing the Ballast PWB? If so, what is the level of difficulty to replace this part? I've built a few desktop PCs and a HTPC, but that's about as far as my level of expertise goes.

Thanks for your help!

BTW, I've read so many posts about how the original lamps for the RS40/x3 have burned out quickly. I must have lucked out. I bought my RS40 in 2011 when it was brand new, and my lamp (original 001 lamp) lasted past 3000 hours with minimal dimming that I could detect. However, I did have it running in high mode for the last several hundred hours. I'm now thinking that I should have replaced the lamp prior to it blowing out when I reached the 3000 hour mark. I'm thinking the blow out may have taken the Ballast with it. This is my first time replacing a lamp, so just trying to figure all this stuff out.
Okay so I got the estimate back from Mendtronix. The problem was diagnosed to be just as you guessed; the Ballast PWB. The part was listed at $195. They also are fixing my front IR receiver, cleaning optics, filters and testing all functions and updating firmware. The total came out to $495 plus $39 return shipping. That's not bad at all. I'll post again once everything is done.

I have a question for you guys regarding my RS40. I haven't had any issues other than the first bulb went at 227 hours. No lock ups, no IR issues, no HDMI handshake issues (yet). My second bulb has 492 hours on it. But lately I've noticed black levels have no gradient to them. In dark scenes it seems the black levels are getting crushed and there is no distinction to gradients. That makes dark scenes impossible to view. Bright scenes seem fine. I have calibrated it with the AVSHD disk. I've tried many movies and the dark scenes are all the same - too dark. This is a recent change as previously I could see the darker scenes no problem. Any ideas?

Thanks

Thanks for the info! I'm thinking that I have the same issue. I may try to replace that part myself to save on some money. I'll have to do a little more research, though. It's not such a bad cost, relatively. It's just a pain to dish out for a new bulb, then get hit with another $500+ to get the thing running again. Sounds like you're getting the full tune up. Should be running like a champ!

Looks like I paid over $250 more than you for the same power board and the front IR receiver repair. Like Joe Pesci once said in one of the Lethal Weapon remakes..."Screwed again in the drive through".

It's really weird that once per month Mendtronix sends me unsolicited "deals" on projector repairs since I got my RS 40 repaired 6months ago.
