I've been reading this forum quite much in past years but never written anything until now.
I bought HW30ES last year but due to many reasons I was able to install it yesterday. However, there is a problem with the projector: it shutdowns after 5-10s or the latest after few minutes and then starts up again. The unit is placed on the shelf roughly 15cm from the wall and ceiling. There are two air ventilation valves within ~1m range (both sides) from the unit feeding fresh air.
I thought the HDMI cable was the issue (I had to cut the cable and solder new connector to the other end) but it turned out to be fine (verified with other cable). Device producing video was tested (PC and BR player).
Finally I took the unit down and started to think about shipping it service for repair (under warranty) but tested once more running it on a floor. No problems. For more convenient usage I used box under the unit and no problems. Then I installed it back to the shelf and same problems. Tried also lifting up the rear end of the unit to free up air flow a bit and it helped but not much. Keystone was bad so I had to lift the front up and then the problem came back to original level. This morning I tried adding PC fan on the shelf nearby to force air flow but no help - which was strange.
Now I'm going to ship it back to service unless someone has an idea what is wrong here. Very strange problem in my opinion.
I'm thinking of using wall mount solution and flip the unit upside down but don't know if that would give any help. If I need to do that anyway then can someone recommend wall mount rack with adjustable distance up to something like 60cm and that fits nicely to HW30ES. Grey or black would be nice - with reasonable price tag of course
