Thanks for your input. Actually , I have placed a CFL bulb in the holder ,(which was empty earlier) which is also sharing same electrical connection for the projector. Only after placing the the Horizontal lines showed up , I believe. Based on your input for ground loop, I thought this new bulb also would have created some type of ground loop problem. Then I removed the bulb and tried playing the projector. I have run 2 movies after removing it. No horizontal lines. Thanks for your input. I will keep monitoring it for this weekend. And again ,planning to put the bulb and play the projector for few days to get confirmation on this issues. Thanks for your inputs and letting me know, that it is not projector or player problem .:)

Hi, I recently purchased a used Epson powerlite 77c and when I tried to watch a movie there was no color. It just shows as bluish or no color at all. I have tried all adjustments to no avail. The lamp only has 18 hours on it. I would welcome any suggestions.
