Re: Viewsonic PJ50D DLP Projector cuts out

Thanks,
I have already resoldered the power supply board but didn't find any dodgy joints. I will pull it apart again soon and recheck and take some photos.

What i have also found is that if i leave the unit on standby it will always cut out after 30 seconds or so, but if I have it switched off at the wall until i am ready to use it the projector may go all night without a problem ???

Re: Viewsonic PJ50D DLP Projector cuts out

what about a good source for smps unit repairs/testing & info

Hi all,
does anyone have any info on Viewsonic PJ50D.
My unit cuts out after about 30 seconds use.
I suspect the power supply is faulty (possibly overheating) as the power indicator light goes out also and doesn't come back on for about 10 minutes.
I pulled it down and carried out a visual inspection on the board and caps, all seems ok so i resoldered the board.
Worked for one night but the problem returned the next day.
Any ideas of common faults or links to circuit data etc would be appreciated
