Does this happen with all the HDMI inputs. If only the one then jack is bad. Replace the main board. If on all HDMI inputs see if replacing the cable helps.

The red light on the front periodically will start flasing and the picture goes off. It is progressively getting worse.

Standby light flashes twice


The power supply board may have been damaged. Try leaving the TV unplugged overnight so the Tv can discharge and reset itself. If this doesn't work, the power supply board may need to be looked into by a TV repair shop.
If you have some electronic experience and wish to try to fix it yourself, you can most times find a Service Manual for your TV over the internet for less than $20. It will have schematics, diagrams and parts list for your TV.
