Re: Remote Control

Sometimes for and unknown reason the micro processor will simply get confused and something weird like this will occur. By unplugging and hard booting the unit you reset the processor and the problem will most likely not occur again.

We can't change the channel or adjust the sound. We have unplugged and replugged, put new batteries in the remote, to no avail.

Check you remote control with a digital camera:Turn on your camera to view the display on the LCD screen. Point the remote control to the camera's lens. Press the remote controls buttons and observe on the camera's LCD screen or viewfinder that the remote control emits infrared lights from the transmitter IFR light. If you don't see any lights on the camera's LCD display from the remote control, then the remote control is bad.

After short warmup period remote control will not change channels or display TV Programme guide. Unit must be switched off and then back on for remote control to operate properly. Problem repeats after a...

Easiest things to check first:
Are your remote controls working: check batteries; check infrared on remotes by viewing with camera phone/camcorder; make sure your remotes are programmed properly for the device.

Another option: do a hard reset of your TV-unplug it and let it sit as indicated in the manual; then turn it back on.

Another option: unplug the TV and use an air-can and thoroughly dust ALL the component input/output access points on the TV. Turn the TV on and see if this works.

Another option: unplug the TV and connect standard 1/8" headphones in the output of the remote OR headphone jack on the TV [try both]. Turn the TV on and see if this helps.

Finally, if these steps do not work: unplug the TV and let it sit for a good hour. Open up the back panel carefully and air dust the remote control sensor. If this does not work, change the remote control sensor.

Hope this helps.

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.
