Sony Vpl-Hw30es heat waves on screen

Hi all,

Had a vpl-vw60 for like 6 years and finally upgraded to a hw30. Things are great except I see heat waves in the screen when light colored images are up. It's like heat from the exhaust port on the projector is blowing in front of the lens and you can see the heat like water like streams of motion on the screen.

My vw60 did this and a friend suggested I cram foam around the lens on it and it fixed it.

The hw30 does have a gap around the lens. I wrapped a black sock around the lens Asa test and it didn't fix it.

Has anyone else seen this and how did you resolve it.

Thank you,

Jon

Just enjoy HD in whatever form you can (Sat, Cable, D-VHS, OTA, HD DVD, or BD).

Perhaps an easy fix would be a little computer fan to blow in the opposite direction and re-direct the exhaust ? I haven't heard of this problem before. Is your projector extremely close to the ceiling ?

What's you definition of extremely close to the ceiling? My projector is in the back of my 16ft long projector is 7 inches from the ceiling.

I am surprised I am the only one to have this issue so far....

That's pretty close - I've had plenty of people hanging their projectors off of 12" drop tubes to 24" drop tubes. Anyway, perhaps the air flow in your room, due to the location of HVAC registers and air returns, causes the general air flow to go across your lens, in addition to the projector exhaust.

Weird. I had a VPL-VW60 for six years (and a VPL-VW50 before) and have never had such an issue. My projectors were 7 in from the concrete ceiling using a Sony PSS-H10 support.

If what you see are indeed warm air waves, perhaps you should check the air circulation in your room.

I've seen the "heat wave" issue on the vw1000es. The problem, for me, was caused by restricted exhaust air flow causing the projector to get hot. The projector didn't complain it was too hot, but nevertheless I was seeing problems on the screen. When I corrected the airflow the "heat wave" went away...

Could this be the source of your problem?
