I HAVE A HL72A650 DLP TV. AT FIRST THE TV STARTED TURNING OFF AND ON . I LOOKED ON THE WEB AND WE HAVE TRIED CHANGING THE LAMP AND THE BALLAST. THE TV IS SILL TURNING ON AND OFF. THE SCREEN DID COME ON...

Sir reset the lamp hour meter if you replace the lamp. Aim the samsung remote at the front panel where the infrared sensor is located, press the following keys on the remote in this order, Mute, 1,8,2,Power. Wait until the your tv screen lights up with the words "loading factory" on it. Press the "down" direction pad on the remote to select "option" from the list of choice that appears on the screen. Press the "enter" button on the remote, select "reset lamp timer " from the list of choices presented on the screen. Press the "enter" button on the remote. Turn off the TV with the remotes power button. Then wait at least five minutes before turning ON again your tv hope this helps good day and best regards.

3 lights flash and TV will not turn on

Since your TV is a DLP, it could be the lamp or the color wheel. The flashing lights are a service code. Some TV manuals will describe the code and others require a service manual for the codes. Either manuals can be found online at a reasonable price. Here is a site I use.

My sharp DLP allows for the user to replace the lamp pretty easily so there is a chance you could be able to replace yours if that is the problem. The color wheel is a different story. That will probably require a service technician.

Good Luck

My standby/temp light is blinking and my lamp light is blinking. tv is about two years old. Just started happening out of the blue. It will come on for a few minutes. I have three dogs and it gets dusty...

check the lamp if you havent changed it before that would be the easiest place to start. if the lamp is popped you will see glass pieces rolling around in the lamp.
