Samsung DLP HL-R5667W not turning on. Showed purple spots on screen so I shut off and unplugged as this has worked in the past. TV will not turn on as of last night. This is the 4th time this has occurred. Usually, I can get the TV to turn back on eventually after unplugging and letting it sit overnight... Does the lamp need to be replaced or the DMB Board?
Lamp light will blink a few times in the front and then it will eventually turn to stand-by mode when I try to turn it on. If I hit the power button before it goes to stand-by mode, the timer light in front will blink on.

make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast. Call a local tv repair shop to further diagnose the problem.
You may have a colorwheel going bad. The bearings start going out and this is an indication of the failure. The colorwheel is located in the light engin e therefore you may want to get a qualified tech to look at it
This Tv make a lot problems with the color wheel and fan thermostat, lamp cool. Need be check the color wheel first. I am suggested dont have nothing on the back cover ( make hot or not ventilation). More information parts at tritronicsinc.com Thank you
Afraid there is no simple answer to this. This set has multiple things that could shut it down, one may be the balest needs a upgrade , this could be why it seems to be eating lamps. Another is what sounds like a fan is a color wheel , these have known problems of failing, and when this happens sometimes they shut down the set. And finaly does the set have good ventalation, overheating can cause huge problems with this set
Color Wheel problem.. to generate colors on a dlp the light is shine through a motorized wheel. that has different color filters on it. this is a motor and anthing that moves will eventally wear out. i just replaced the color wheel on a samsung today. standard for this to go out in about that time. i believed our shop charged 250 to put a new one in.
