I have a solid yellow lamp light on my Mitsubishi WD-52525 that I can not get to go away. First I replaced the lamp with a after market lamp and the light did not go away, then I cleaned the filter and the light did not go away. I then figured the problem was the after market lamp was also bad so I installed a OEM lamp and cleaned the filter agagin and the solid yellow lamp light remains. Not only is the light on but the picture appears to be on the dark side. I could really use some help here. Thanks.
