SOURCE: Samsung DLP 62 inch turns off by itself after being switched on

I had the same issue but instead of shorting out the sensor, I removed the bulb assembly, cleaned the interior of the assembly and TV the best that I could with a vaccum and small paint brush. Once cleaned, I reinstalled the bulb assembly and the TV has worked for the last eight months with no problem.

SOURCE: TV Turns off and on

How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.

It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.

3 flashes indicates that the lamp is not seated properly or that the lamp door is not closed properly. Try removing and plugging tne lamp back in, tightening down the holding screws and reclosing and tightening the lamp cover. This should take care of your problem, Please be sure to rate this solution. Thanks!

SOURCE: 52"rca hdtv lights blink will not turn on

Thats the classic sign of the CP150, CP120 and CP114 capacitors having failed. By trying to power it up over and over the caps will eventually charge and the set will function untill you power it down. You can get the CP150, CP120 and the CP114 repair kit at and the kit contains the CD with repair instructions.

Hitachi 32LD8700 - TV won't turn on although has power

The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.
Hope Ya Fix It

Wont come out of stanby mode ??

The trouble your describing tells me that theres a short in the output circuit of this unit. Unless you know how to troubleshoot solid state electronics, Please take to a pro to have it serviced , as there are no user serviceable parts inside this unit. Good Luck
