TV works for a week, then powers off, blue power light flashes on and off slow and remote or power button has no effect. After unplugging and plugging in, power comes on for a few seconds, then off. After about 15 or 20 times, it stays on and working for a week, then does it again. No set time, semi-sporadic, but always the same result, powers off but blue led power light flashes slow. Once led flashes slow, you can't use the power on or off, HAVE to unplug to use either power button again.
