Samsung HL67A750A1FXZA Repair Success Stories ...

you need to test the fan if it is working or not or better replace the fan with a new one.there must be shortage of voltage coming from the fan thats why the unit turn itself off.over heating of components near the fan might be the cause because your fan is malfuntioning thats why you got a keep getting the message check the fan better replace it..

You can attempt to remove the back cover, but there is a very delicate mirror in the back. I'd just move it away from the wall, used compressed air to clean out the fans, and put everything back together. Just make sure you don't damage the color wheel or light engine.

lamp, ballast or colorwheel

Has it been getting loader lately? (fan noise)
if so check link it could be the common fault described below
Samsung Color Wheel

Defective Lamp,maybe and Ballast Board may well be the problem it is what turns Lamp on Look on line Encompass Parts Dist 1-800-638-3328 Ballast Board also has small fan mounted in front of it!

That sounds most like the color wheel,
to change that you need to have some skill in electronics, I would recommend to take it to a shop

The 3 lights on the tv are there to help you diagnose the problem. There should be Timer, Lamp, and Temp. If all 3 are blinking, the LED may be defective. If standby and temp are blinking, it's a problem w/the cooling fan.
Let me know if that helps.

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

Have a 46 inch behaving the same way. I have the extended service contract, so they are getting a calll tomorrow. I ll post what they say
