      Obvious question that the batteries are OK. Does the sets led indicate that the remote has been pressed.
      Willing to help but I'm no expert.

        Yes tested the batterys and there fine tried a few panasonic remotes but no luck
        And nothing on the led sensor to show the remote is working at the present time I'm having to use the side controls

            You can check the IR OUT of the IR receiver module with DC Voltmeter, you should see it changes when it receives the IR signal from the remote, but this test does not verify if it is putting out the correct signal or not, it just shows the activity.

              Hi, Please can you tell me how did you stop/not get the 'white halo effect' when putting theLED backlight lens back on?

              Thanks

              (Tx-55cx400b)
              I'm waiting for a few bits to arrive to test properly, the screen was blank so I've done the strip down and checked and I have 3leds out (fingers crossed that is the only fault)
