Suddenly my TV will go on stand-by mode within a few seconds from turning on. Details: if left unplugged for a while it will work just fine. I left it plugged in and in stand-by mode ( so that I can turn it on/off using the remote) a couple of days and when I tried to turn it on , using the remote control, I heard the sound and before the image comes up, I heard a "click" and the TV went back to standby. I tried using different inputs or turning it ON/OFF from the power button and it behaves the same. At this point, I need to know if this is easy/cheap to fix or, I just recycle it?! Any info is appreciated.

Thanks in advance!
