|
|
I'm not going digital I promise. My xg1100 is still going strong and I have a 9pgxtra to fall back on
But....
I've been given an infocus lp290 with a dodgey psu and before I go and just replace the psu I'd quite like to have a go at repairing it to save a few pounds. Its going to go to a friend who doesnt have the space for a crt and she has bad eyesight too which will help
I've searched for hours on the net and have asked on av and avs forums but to no avail.
So if anyone has the schematics or can even take a photo of the area on the psu where the resisters have blown I can happily geek out tonight trying to fix it.
Cheers
Rob

Why bother? This is an old 4:3 business projector. Heck $500 will get her a much much better digital home theater projector. Unless she is completely blind, it would be $500 well spent. I would not spend more than about $2 to repair it.

These are home theater sites and this was not a projector that would have EVER been used for home theater--so you are unlikely to find info there. Since it is so old, the service manual may be floating around out there.

All I can say is GOOD RUCK!
IN fact, I DARE you to call the InFocus 800 number and TRY and buy a part, let alone a schematic. I posted about this about 2 years ago I think. Go waste some of Infocus' 800 money, get bounced around the world, talk to a nice guy named 'Simon' in India, then call the 800 number for the sales department in Portland, Or, who will tell you that they DO indeed sell parts, demand to talk to a parts/customer service person in Portland, and then get the royal run around.
Please do that on your coffee break, post how you made out..

Hey thanks for the replys.
$500 is way beyond anyones budget at the moment. And I was figuring that if I knew the rating of the resistors that are missing it would indeed cost me less than $2 to fix.... Hopefully
And I'm not even going to think of approaching infocus lol I've heard many a tale about their support
I've found a guy on ebay thats got a psu for $80, I think I might just wait for one with a dead bulb to come up on ebay.
Thanks

That's about all you can do, is find another one that has other problems.
It's a rule in 'lectronics that if a resistor is burnt up, something else somewhere is shorted, causing the resistor to smoke. Resistors don't just burn up by themselves for no reason.
