My Sharp Notevision was overheating after replacing the bulb. It would work fine for ten to fifteen minutes, then the lamp icon would blink in the bottom left corner of the screen before the unit shut itself off. Once cooled off, the unit would function normally for another ten to fifteen minutes. However, the last time I used the unit, a large round yellow stain spread across the screen. Can you help???

The blue device is dying allowing green to shine thru instead of white. Very common problem called color decay. Happens on average about evey3-4000 hours. I suggest next purchase a dlp product, they are immune to this problem. Good luck
Perhaps clean the side filter as well as per page E-46 in the manual on following link:

bad power board or blown fuse. If you feel comfortable you can take the out case off and follow the power connector to the board. You can then check the fuse. Make sure the unit is unplugged before doing so. If the fuse is fine then you will need to replace the board as it probably has a bad capacitor or resistor. You can find a power board online but to be honest, its probably not worth the money to by a new one. Would probably be cheaper to buy a used one with a bad lamp and cannibalize the power board out of it.
I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben email@example.com..
No special tools needed. these units (dlp projectors) are designed so the lamps and color wheels can be changed out by the user. Some can figure out how to do this easily without instructions but to be safe just do a quick search and find step by step instructions. You can also refer to your owner's manual.
Your lamp is not lighting up most likely. Try removing the lamp assembly and clean the contacts. If that does not work then you will probably need to replace the lamp. Also try resetting the timers. Refer to you owner's manual for info on how.
