Hi, May I inquire if your On-timer problem was fixed, and if so, how did you do it? My sister-in-law's TV is doing the exact same thing. The On Timer red light keeps blinking. When you unplug the power cord to the TV and plug it back in, then turn it on, it only stays on for about 5 seconds or so. Any help or suggestions you can provide would be GREATLY appreciated. Thanks, Kimmy
