please help me diagnose

Post by pmc7855 » Mon Jan 11, 2010 11:23 pm

I have a samsung HLN437W1X/XAA DLP T.V. at times the lamp will not turn on causing the 3 cycle process until all 3 lights start flashing, but if I unplug it and restart it, it will usually work fine. but today I noticed that the lamp was on(I looked thru the vents) but no picture until I unplugged and replugged the power cord, then all fine. can someone please help me diagnose the faulty part so that I dont replace unnessasary parts? thank you btw the lamp hours is at 6900.
