It depends on if its a rear tube set or a micro-display projection. First step would be to try and unplug the set for a 12 to 24 hour period. Still not comming on? The next step would be to get a service manual for the set from http://www.servicemanuals.net. If its a tube set your first going to need to look at the standby power supply. Make sure all the voltages are there, and then if all looks good, go to the sweep supply and see if the set is goinfg into a shutdown because of a High Voltage problem. If its a micro-display first check the bulb circuitry and see if its in protect mode because of a bad bulb. Some sets have LED's on the boards to tell you this, but every model and make is differant, thats why you need the service manual to interpret the lights. Also could be a power supply problem in these sets also. If your not a tech I would highly advise you to have one look at your set because these sets are all solid state, every part is soldered in printed circuit boards and your going to need to know how to use special types of test equipment. Let us know if you get it going or what had to be done to get it going. Good Luck

Yes it can if theres a fault that makes it shut down it can or a power line glitch can do it too.
