Why is my projector image dim?
In the case of dim images, please check the following:
Check that the lamp has not been set to 'Economy Mode' by activating the projector menu. Then highlight the icon that looks like a spanner and a screwdriver.
Now move the arrows down until you get to the light symbol, press select and scroll left ot toggle the different lamp modes.
If after changing your light mode your image is still too dim, make sure to try your best removing any source of direct lighting which is shining onto the screen (such as glare the sun). The next stage is to try another lamp from a known working projector. Either the lamp could be edging towards the end of its life or your projector could be in need of an optical clean; trying another lamp will help to diagnose any of these issues.
