Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; to which you want set-up codes; in the "Search box at the top right of the display window" to get gathered related posts.

Truetech 10 inch under the counter tv is stuck on channel 2. I need 3. Channel buttons on tv & remote do not change 2 to channel 3. Unplugging, Resetting hasn't worked Any ideas?


Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Sound is pinned at 100% output. Remote nor physical buttons on device are working.


If any of the buttons on the remote or tv work, then try going into the menu and turning the sound down manually.

I have a 39 inch element tv i cant program the cable channels


Typically you can access the menu, select "tuner" or something similar, make sure you're selected either on CATV or ANT (or similar), then do a channel scan. Should be pretty straightforward. Oh, and make sure you actually HAVE cable. If it's digital cable, you may need an external converter box for it to work.
