Why does my Panasonic Viera VT50 have no picture and red led blinks 3 times


First thing, check the HDMI input and make sure it is firmly connected, same for the power cable, obviously. My Samsung goes similarly nuts if it detects no signal from the currently selected input but after 1-2 minutes it eventually stops and I can change the input source.

LG 32cs460-us TV black screen red light blinks 3 times


I can give you some advice on the first thing you need to try. Unplug the tv for 10 minutes. Plug the tv back into the wall or power strip. Try powering on the tv. This may work or may not. It is important to try this before moving on to more complicated troubleshooting.
