TV won't tune above channel 12?
Hi there,
I have been using this television for 2-3 years with no problem until suddenly it will not tune channels above #12. It is connected to my cable through a CAT5 connection. When I use the remote to scan for a station, it actually stops on the channel number just above the one desired. For example, when trying to tune to Ch 55, it flashes the image at 55, but stops on 56, which does not have the image (just noise.) I tried to connect this to two other cables in my home and get the same result. Also tried the connection in the family room set, which tunes just fine and same thing. 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.
