Question about Televison & Video
The TV seems to be working as the menu and input screens display and function properly. however when selecting any TV channel it displays the channel detail including the current program but then does not display any picture or have any sound. The same applies to all other input sources. All input sources seem to work, as you get No Signal message if the cable is disconnected, then goes blank when reconnected. Just no picture! Is this a hardware fault of firmware issue? Have done a factory reset ... no change! Anyone please !
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. 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; visit the site linked here.
