TV SHUT OFF, HASPOWER, RED BLINKING LIGHT, WON'T TURN BACK ON, WHATS THE PROBLEM ?


If the red light is blinking, then it either does not have a good power connection or its in a diagnostic mode. The red light should be solid not blinking.

Blinking red light no picture


No picture or do u have a blue (or some other color) screen? And the blinking red light, is that the indicator light down by the power button that is blinking? I have the same tv and very similar problem, i have a blue screen and the red indicator light is blinking. If you have gotten ur problem fixed I would love to know how, or vise versa if I get mine fixed.

Red/green lights both blink and tv will on turn on


Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

Blinking red light.Checked all cables. I replaced Hard drive...still problem exists. Wondering if power supply could be problem


When one light from the four lights ring itself changes from green to red, it means that a general hardware failure has occurred or is imminent. Blinking of one red light with an error message like E66, E67, E68, E71, E74 or E77 means a repairable problem while the one red light blinking without error message means some critical or irrepairable problem. The problem can be avoided by restarting the Xbox 360 console but if you have not received any error message with one blinking red light then the problem is irrepairable. The console will behave the same way and you should understand that one or more of the hardware components in your console have stopped functioning due to hardware failure. If you receive an error message with one red light blinking then the problem is reparable and the system will definitely start working. It means that there is some hardware problem with the Xbox 360 console connection occurring due to the misplacing of cables in the ports. Turn off your Xbox 360 and disconnect all cables, now reconnect the cables and switch on the Xbox hope this helps.
