Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems.

The green light blinking three times and not stopping until the set is unplugged, is a failure of the Mainboard in the set. This is the board that processes the HDMI and AV Inputs. Offhand, the screen getting dark is caused by a failing Lamp- nothing to do with the HDMI ports.

That said, you have somewhat conflicting symptoms. I need to know the following:

1) When was the last time the Lamp was replaced?

2) If you unplug the TV and plug it back in, does the clicking and green blinking occur right away- or only after you press the power button?

At any time does that green light tun red- if you leave it long enough blinking?

I'm unsure why you're not able to reply, but can you please simply tell me when that Lamp was last replaced (if ever)?

Customer: replied 1 year ago.
The lamp was replaced less than 1 year ago.
The lights only blink when the power is turned
The green light never turns red
Expert:  Aric replied 1 year ago.

Thank you for the reply. This blink code, and the screen getting darker indicates your Lamp has failed, and is common when anything but the $105 OEM lamps are used.

Per your manual:

Green blinks continuously
at 0.5-second intervals;
Red is ON (solid).

Means the Lamp has failed and needs to be replaced.

That said, you will need to replace the Lamp to fix the set. The OEM lamp for your model can be purchased at the link below:

Do you need further assistance with this?

Expert:  Aric replied 1 year ago.

The set is cycling repeatedly because the ballast keeps trying to spark the lamp and it cannot. This directly coincides with the picture getting darker prior to this.
