Was at my brothers place tipping a few and watching PJ last night. After quite a few I decided to throw up a the convergence screen just to see if it had drifted much since the last time I tweaked it. It seemed to be converged OK but all three colors were out of focus. It looked like someone had messed with all 3 lenses. I tried focusing the lenses but realized that all 3 lenses were already focussed optimumly.
This is where it gets weird. Once off the menus the image looked OK. Perhaps a little soft but not out of focus like the menus and test patterns.
Which board has bit the bisquite allowing the menus to be soft but the video sharp.
Yes I did tip quote a few but I'm sure there is an issue with the PJ and it isn't a basic lens or electronic focus issue.

It happened to mine once a while, especially the red color. Did a mechanical len focus all would be fine again, weird. Could it be the curvature of the lens changes with time?

This sounds like what Happend to my rear projection Mitsubishi. Pic look great but on them enues it was all fuzzy. Turned out to be a bad red tube. Not sure why but it affected all the clors grid patterns weird is right. Maybe its the same issue ?

Beer goggles? :D
Go into your electronic astig controls and move the numbers by 2 either way. You will see it pop back into focus. It has something to do with the astig board. It's a known issue on some machines.

I had a similar condition and (not being a tech, I'm therefore an optimist of the highest order) pulled the FCM and cleaned the contacts with Caigs/ Deoxyt. That took care of the problem.
I never had the problem before I ceiling mounted. Until I recently modified the retaining methodology for the HDM and FCM it was the same deal for me, eg, one of the two boards would happily creep out assisted by gravity and I'd either lose the pic altogether or it would be very soft...the menus looking the worst.
I'd be interested in knowing if it turns out to be something more sinister.
