I have a Hitachi CP-S240 projector. It works fine but now projects a yellow blob on the screen. It looks as if someone took a highlighter and colored on the lens - I cleaned the lens and that is not the...


I work for a company where we take care of around 7,000 projectors. We have recently come across this same issue in this model and several other Hitachi models. We have figured out that it seems to be a main board issue, after testing and checking of the lenses and other things. The main board ended up being the fix. Hope this helps!

Black blob on bottom rh of screen,vertical & horizontal lines


The blob is a phisically damaged part of the LCD screen. Unfixable, the screen must be replaced and it will be expensive.

Sounds like a scorch mark on the polerising filter, this can only be replaced by an engineer cost around £70 ($150).

To all that are experiencing the blue blob. This is result of poor maintenance. Projectors must be kept clean on all air intakes. This is to help you all understand the failure cause. Usally not worth repairing.
