Question about InFocus TD40 40 in. LCD Television

Open Question

Suspected power problem

Got one of these TD40's and the past year its been cutting off. I turn it on and it will run for 10 hours straight no problem. but sometimes it cuts off after 30 seconds to 2 hours. the light on the front just blinks amber. called the company it cost over 1000 bucks for them to fix the problem. Is their a tech manual available. If i know the cause of the problem as long as its not the main board i think i can fix it. Has anyone else experienced this problem can you give me some tips.

SOURCE: A power cut whilst the projector being used,

it could be the fan, colorwheel or high temp. remove the lamp and turn it on. do the fans spin? if not, replace the fans. does the colorwheel (colored glass wheel near the lamp) spin? you should be able to see it and hear a high-pitched whir. if not, replace the colorwheel. if the lamp was still hot when it was turned off, you need to let the fans run and cool. then unplug it, plug it back in and try again.

Blade wonders on straight cut


When doing any straight cut use a straight edged piece of something to run the jig saw along, using as a guide, this will usually keep it all straight, sometimes it can be a loose blade, or a bent shaft?

I have a 10'' table saw


If it cuts straight it's fine. It's likely just some play in the bearings. I wouldn't worry about it unless it starts to cut not so straight...

Dometic Duo Therm Ac, Fan runs, Compressor cuts in and out?


your compressor is locked up. i would try replacing the round start capacitor. you need to check what the exact rating for yours is but I believe one of these two will work for ya. In the meantime do not continue to try to run it, it will kill the compressor.

Cutting straight


The tension on the blade. the position of the guide rollers, and the condition of the blade are all important to get a straight cut. You might want to try lowering the guide rollers down close to the wood being cut. good luck.
