SOURCE: red light blinking, tv doesn't start

Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.

TV does not turn on. Stand By LED blinks 4 times and pauses and blinks 4 times again Tv will not turn on...when plugged in the red stand by light flashes 4 times...you can hear the tv turn on but a black...


On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.

Power light blinks red, TV doesn't turn on


if you are not technical i sugest you have this checked out by a professional most probably a fuse has gone from iside or your driver board has gone down. The blinking should be normal after you have turneds it off because some capacitors will be discharging.

Tv will not turn on


The blinking red light is telling you that the set did not start up due to an overvoltage somewhere in the set. Most likely the main power supply has a fault like a bad regulator IC or a component associated with it, or there is a fault in the sweep power supply somewhere. if you have no electronic repair experience, play it safe and call out a tech to assist you with this repair. Good Luck.
