To anybody who can help. I recently replaced the lamp on my TV . After also getting the grinding sound I have read so much about I tried to replace the color wheel but the new one was defective. When I replaced the lamp the picture still worked just kept hearing the grindingsound. So until I get the new color wheel I put the old one back in but I am now getting a Check Fan 1, 2, 3 with the 1 in red font. It will flash for a few minutes then eventually shut dow the TV. Anybody have this problem? Do I need to also replace the fan? Any help is much appreciated.
