Help with infocus screenplay 5000

[Ghost22]

Hi guys, Im new here, I've posted on a few other forums and havnt yet been able to get an answer, Tried searching here as well, but nothing specific to my model.

Im trying to repair a projector for my buddy, infocus wanted 420$, not including shipping or handling. I figured that was outrageous. I opened her up, and the power supply is fried. Looks like 6-7 resistors, and at least one cap. Problem is, things are melted so bad i cant tell what half the stuff is. I also havn't repaired a power supply in 3-4 years, so i am a bit rusty.

Is there somewhere i can get a schematic? Or does anyone know of a place that will sell replacement boards? Infocus refused to sell me a board because i am not an authorized repair center. Or, has anyone here worked with this power supply before?

It appears to be a magnetek model 3e40-20-100. But Google does not find anything.

If this is the wrong forum, or if this has been solved before I apologized. I did try to search, but could not find any useful info for my model.

Thanks
Adam

which board? lamp power board or main power board ?
do yo have some pictures?

 

[Ghost22]

Im new to the projector scene, but im going to have to go with it being the main powerboard. Its where the AC plugs in, and it has a small cable bundle going out to the main board on the digital, with a few grounds, and assorted voltages that i dont know 🙂


I can have pictures, but not till later today, camera is in car, its snowing, and its bed time 🙂

But yeah it just looks like your every day powersupply. Does have somethings, i think specific to lamp related things though. Such as a wima film cap (the blown cap c504 is directly opposite side of board as the wima).

Hi !
I can look for most board og projector, I sell the whole board but not some transistor.
I need some pictures of whole board .

 

[Ghost22]

Ok heres a picture from the top.
I hope it posts, The first two pictures, didnt show up after mod cleared my post.


That is about as detailed as i can get it, with under 100k posting limit. I can get any numbers you may need from the parts. Just looks like a switching powersupply to me, but its out of my league.





EDIT. Thanks mods for removing my moderation waiting thingy 🙂

Update, after calling one of the repair centers out an email, saying blah blah i know it doesnt really cost 400, " i hope you sleep well at night ripping people off"

They offered to sell me powerboard for 120$ plus shipping.

Though i'd much perfer to repair this one still if it is possible

 

[Ghost22]

[Ghost22]
