There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Screen went blank and there is a flashing red light on set


I can only assume you mean that the power light is flashing, not that there is a flashing light showing on the display panel.
The speed and number of flashes you get is the troubleshooting code to tell what's wrong with the set. More info is needed.

Red blinking light


Hi, Ephraim. The flashing red light indicates that the device is showing "low battery". It could be that the LG phone charger fits the charging port on your bluetooth headset but it is not compatible with your device. In order for you to know that it is charging, the device should show a steady red light(means charging).
Please take a look at the table reference below.
----------------------------------------------------------------------
•With the Charger Plugged In
______________________________________________________________________
•Headset Indicator Headset Status
Red-----------------------------------------------Charging (battery level less than 50% charge)
Yellow-------------------------------------------Charging (battery level more than 50% charge)
Green--------------------------------------------Charging complete

Three blue flashes------------------------Powering on/off
Steady blue --------------------------------Pairing/connect mode
Rapid blue/purple flashes -------------Connection successful
Quick blue flash --------------------------Incoming/outgoing call
Slow blue pulse --------------------------Connected (on a call)
Slow blue flash ---------------------------Standby (not on a call)
Slow red flash ----------------------------Idle (not connected to phone)
Slow purple pulse -----------------------Connected call muted
Steady red ---------------------------------Attempting to connect
Quick red flash ----------------------------Low battery

Note: After 20 minutes on a call or of inactivity, the light stops flashing to conserve power, but the headset remains on
----------------------------------------------------------------------

Hope that'll help you in some way.

Flashing blue red


Switch off the TV manually, switch off the power outlet, remove plug and retry after 48 hours. Then if the problem persists, this might need attention by a qualified service technician.
