i believe your problem is heat the bulb is getting hot and the air or fan is not working properly so when it hits temp it automatically shuts off check your fan air flow filters etc

Hi Bob

This most definitelly NOT the lamp.

It is unfortunatelly your Mainboard that is at fault , and will either need repair or replacement as this will only get worse as time passes.

Hope this is of help !

Samsung DLP

try this and see if it makes a difference
open the lamp door look for the blue switch(bottom left i think)
take the loose wire(blue and white) wrap it over the switch to hold it back
and while your back there make sure you dont have a lot of dust blocking the vent on the back cover

Blue patch on left side of screen

I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.

Blue patch

you didn't state how many hours are on the unit, but I'm guessing close to 3,000 hours, that is when most brands have LCD panel failures, due to the heat over time the coating on the lcd panels burns off, the panels start to burn up, and it gets worse with time, and you notice it more when you put a fresh bright lamp in. if it is low hours then you could have a bad lamp, that casts a bad tint, but it sounds like fried LcD panels, a sure way to tell, is put up a white back-ground screen and see if you see discolored "BLOB" in the center of the screen.
keeping the filters clean, and the projector cool is the best way to prevent this.

Hi,

Unfortunately, the value of projectors drop quickly after the production run ends. You will most likely find that the price of the blue prism will be higher than a comparibe working projector of the same model on ebay. I have a Panasonic PT-AE 900U, 1100 lumens 720P 5500 contrast. To replace the main board (if you can find it) cost over $700 from a supplier. The same projector used are going for $300 - $500 in working condition on ebay. I just bought another one and it gets a great picture plus I have a second bulb as a backup with a few hundred hours left on it. I still haven't thrown away the ailing projector in hopes of someday finding a cheap one for sale with a good mainboard and a problem else where. Now I can afford to wait for one to become available.

Hope this helps,
