i cant turn tv on with remote

Maybe the problem is in the remote. To check the remote use a cellphone camera or maybe a digital camera will do. Just focus the camera on the remote LED it is located on the top of your remote, while pressing the buttons of your remote put the camera on the LED if the remote is good you will see a blinking lights on the camera while pressing the buttons of the remote. If the light doesn't show try to replace the LED on your remote or maybe just clean it also clean the button panel with a pencil eraser, Usually the remote control is the problem, Hope this may help you if the problem still exist just email me...

3 yr old KDL-40V3000. Remote suddenly stopped working. Changed batteries twice - didn't make any differnence. Then noticed no LEDs lit on TV front pane! But TV is powered on. Also TV can be operated fine from local button on top panel. Could it be a remote sensor/board problem? Is this something I can fix myself?

my samsung led remote control has just stopped working and i can't get it to work again. I've changed the batteries and i cannot find the reset button. I've unplugged the power from the wall and still no luck. plz help

We need to find out first if the remote is putting out the IR signals or not, or the problem is in the TV IR receiver module.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

The ML-L3! The laser light does not come on. I tested the battery. It is good.

How do you know it's not coming on? The LED (not a laser) puts out infrared, normally not visible to the human eye. If you have a point&shoot digital camera or a dSLR with LiveView, try taking a photo of it and see whether it lights up when you press the button. It'll probably show up white. You might try a TV remote for comparison.
Also, try cleaning both the LED window on the remote and the remote sensor on the camera. And make sure you're pointing the remote at the sensor.

remote control not working

It could be either remote is bad or remote sensor located at tv front is not working.
You can test remote with help of any digital camera, watch remote front through camera and press few buttons on remote, you will see infra red led blinking at remote front, that means remote is good and working. Remote sensor in tv is defective and need to be replaced by qualified tech.
If infra red led of remote does not blink pressing any button while watching through digital camera then problem is remote, buy new one to solve the issue.
