A pal has an awfully expensive home cinema set up - perhaps 5 years old.
The projector is an Italian DLP type (can't remember the make) which cost
the thick end of 10 grand. Most of the rest is badged Linn. The firm who
installed it all (nice job) are no longer around.
The output from the projector was getting a bit dim so he decided a new
lamp was needed. The quote from a dealer was 1200 quid. ;-) He got the
lamp from Ebay for less than half that and asked me to fit it, as he
doesn't know one screwdriver from another. ;-(
Proved an easy job - but I suspect the dealer would have done a good clean
at the same time. And I wasn't going to attempt a full strip down without
a service manual - not available. So just carefully cleaned everything I
could including the various fans.

The light output is now fine - but it seems he hoped it would cure another
fault. That is moving 'diagonal' wavy lines - looks to me like RF
interference.

If you put up the various test patterns internal to the projector, these
are clean. Just the DVD (the only source) has this patterning.

The whole installation is built in and will need quite some dismantling to
get at anything - even just to try a different DVD player.

The strange thing is it appears to use the S-Video input to the projector
- since it has DVI and components.

Anyone come across this sort of fault before I start ripping things apart?
