Thanks for mentioning the USA model. Might find more info on the projector.

In the meantime I made a test disconnecting all 3 lcd colors (R, G, B)

I still have a red screen, which basically tells me that for some reason the green light travels through the beam without anything blocking it. The other two colors obviously get blocked, the green not.

Is this kind of a polarizer in-out issue? Or what should actually block light to mix colors?

Any clues?

There are three LCD panels inside the projector which is what opens and closes to create colors. Watching some FixItFrank videos can help shed some light on what is inside of the projectors themselves and how the internals work for LCD projectors.

If you want an answer from the man himself, you will need to join the Projector Central group on Facebook as Frank hasn't shown up in these forums for quite some time.

Mitsubishi XL5U ColorView
Projector Specs
Projection Calculator
Hey guys, been trying to get a fix on an issue that is bugging me. Hope someone can give an idea. We recently had to change the lamp on our Mitsubishi XL5U which we use for class lectures or presentations. Sent it to a shop for changing but they wanted to scam us and ended up removing color LCD flexes when our man stepped out to make a call and said that the issue is with lens so will need to keep longer for fixing instead of a simple lamp replacement. We asked him to bring the projector back and when I checked it myself found the issue and after lamp replacement when i switched on the projector the projection was as is in the picture. When machine switches on, Before splash screen the light shown on screen is complete without any interruptions. But as soon as the splash screen shows up the right side has no image and top is duplicated below.

Hi, I have this old projector viewsonic pj458d. It turns on, but after 10 seconds shuts down, turn off the lamp, make 3 or 4 clickng noise and the the internal fan starts spinning out of control, like REAL fast.

I cleaned the internal fan and lubricated it. Same thing.

By any chance can I show anyone the video by mail?

Heres the repair manual https://dokumen.tips/documents/viewsonic-pjd6211p-service-manual.html?page=4

Thanks!

I have no real projector repair experience, so I can't guide you, but I would advise you to avoid spending any money on parts for this old projector if you can avoid it. As a 17+ year old product, it has a lot of competition from products on eBay which are under $100 for a newer model with better specifications. Most notably, many (not all) newer projectors have a HDMI connection on them which allows connectivity to modern digital sources and streaming devices.

For example, this one is less than $50, has about 50% more resolution, and is also about 50% brighter, and has a HDMI input on it...

So, balance your efforts here carefully.
