Power Supply for Projector

justavert · 29th December 2003, 08:15 PM

Sorry to post this, as its not really DIY related, but...

I bought a Infocus LP730 projector off Ebay a few weeks ago. It worked for a little while and then there was a loud pop/snap. At first I though it was the bulb, but upon inspection it seemed to have no indication it had gone bad (black marks, crack lines, etc). Then I thought it was the power supply since both the green power led does not turn on and neither does the fans.

So my questions are...does this seem like a power supply issue? If so, where is the best place to buy an Infocus power supply? (I can't find this part anywhere including ebay and google)

Sorry again for this post, if you can help me out or if you can point me in the right direction I would be very greatful

The specifications suggest it uses a switchmode power supply.

Other than checking/replacing fuses, you need an experienced
opinion on this.

switch mode power supplies are usually very reliable, if its
gone wrong something else could have caused it.
