Hello all
Recently a friends Marquee has developed an intermittent problem. When the PJ is fully warmed up it will sometimes goes blank. All three tubes go black. Sometimes the image will return on its own and sometimes it needs a power off power on cycle to bring it back.
The PJ is clean and all contacts (board to PJ interfaces have been cleaned). I was considering pulling the CLM and removing ICs from sockets and cleaning those connections. What are your thoughts?
Could I please have suggestions on where to start or ideas other than the CLM?

Thanks
Steve

Steve well the obvious thing is to check for error lights on the CLM and also the ones on the LVPS through the front grill. For the Marquee to blank the video is unusuall, most likely the CLM or VIM problem.
