Hello all

I replaced my lamp with a no-name brand (I think I kept the Housing)
When start up the projector the menu reads fine, but I cant get any picture from my source.
I tried different sources, different HDMI cables, different input (HDMI 1 and 2).
I set input to "computer" and tried different resolutions.
My computer recognized the projector as a "Sony VPL-HW10"
Attached is a picture of how it looks.
Did I mess it up when replaced the lamp, or is the lamp just no good?
I find it strange since the menu looks fine, thats why I thought it had to do with the input.

Lamps are lamps are lamps. So, if you have light out of the projector, it should not impact your ability to see an image on screen.

Yes, I can talk at end about how a bad after market lamp can actually destroy a projector, but that has to do with over heating and burning optics, not making it so you don't get an image on screen through your HDMI connection.

You should go through all your available connections and see if any of them deliver video.

From there, you are in 'take it apart' territory, which these forums don't get into. If you check out FixItFrank on YouTube, he has some excellent projector tear-down videos, but it could easily be hardware related to the input board of the projector which has failed.

This isn't exactly a new projector, so it could be some failure in the board.

Good luck!

Hi there!

What caused you to replace your old lamp?

As the admin said, lamps wont affect the inputs(regardless of how junky). You have a picture which is one step but I agree that you may have an input board problem. This is not an easy repair for someone who isn't familiar with electronics. It may be a problem on the input module itself but it might be a problem with any of the other systems(power supply etc). This is either an excuse for a new projector(stick this one on eBay) or have a servicer look at it. The image looks kind of tinted as well. Might be a deeper issue.

Let me know why you changed the old lamp and Ill look into this issue in the meantime.
