Hi,
Problem sounds in power supply board and most probably few electrolytic capacitors got leaky in output section of power supply board and causing problem.
Replace these leaky capacitors to fix the issue. Local tv repair shop will help you if you have no experience of working in tv circuit boards.
Thanks.

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.

TV won't turn on


When I try to turn the tv on, the green light flashes and eventually goes back to red. A very faint picture came across the tv a few times but didn't stay. The tv is only 3.5 years old.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
