Screen stays black. Powers on but no picture will show. No audio either. SOLID GREEN light shows on the panel. Sony logo lights up. Capacitors are fine. After plugging and unplugging a few things, and disconnecting the power cords, now its doing a new thing. THe tv will power off when I push and hold the power button. And it powers off. But as soon as that happens, a RED light starts blinking 14 times over and over. WHat can it be that needs to be replaced. Thanks

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.
Testimonial: "HI The Knight, thanks for your info. Are you saying to go to here to do a factory/ system reset, http://electronicshelponline.blogspot.com/ ??? How am I supposed to 'see' whats on the screen when entering the "service mode option" while trying a factory reset,if I can't view anything on the screen & it stays black? Btw, I already did many times the hard reset & even left it unplugged days. THanks"
