|
|
I hate to start a new thread just for this but I did do a little searching and only came up with fan mod discussions and the like. I also checked my service manual and it only states what the recommended temperature the projector should be operated in is. What I am looking for is what the temperature inside the projector should be once it has warmed up and reached it's normal operating temperature. The reason I ask is that I'm working on a hushbox and some ventilation and want to take before and after measurements. I'm curious if my XG is running too hot or not hot enough before I install the hushbox. This will help me to know what effect if any the hushbox makes on the running temp.

There was an EXCELLENT thread at AVS, by someone with an IR camera (might even have been on an XG.)
The problem with internal temp measurement is "where?" There are LOTS of different temp gradients, with the deflection coils and certain IC heatsinks being the hottest, but with other areas being comparatively cold.
I would not instrument the coils, but perhaps a few high-flier heatsinks... deflection ICs or the like.

Yeah, I think I might have stubmled upon that thread and I believe it was Chris Bigos that had the IR camera. I could not get the picture links to work but apparently it was very revealing of just where the "hot spots" were. I was just pointing an IR thermometer at the XG last night after 30 minute intervals. Moving even a hair in any direction made the thing spike really high but for the most part I was getting about 95F pointing at the center of the projector and about 3 inches away from it. This was after about two hours of running the projector.

Then use the IR thermometer to pick a worst-case loc (that is'nt electrified with high or medium voltage  ) and make that (or "those") your benchmark point(s.) Hushbox like a madman and watch the same temps before and after.
