Hello Afox5, hi, make sure that there are no user controls or setup that are out of order. as a backgrounder, TV of this type mostly has two boards, power supply and main board. On the power supply board, this has two section, primary that deals with mains voltage and secondary that deals with TV supply current requirements, if you see green light mean that power on the secondary section of the power supply board of your TV is working, but it does not mean that the power supplied to the main board is correct, the supplied current produced by the power supply section to the main board that controls sound and picture needs to be checked, so voltages are needed to be checked and loose wiring, or screws needs tightening, are a common trouble, but some go to extremes like replacement of any boards.

Green light, black screens, no sound, needs new battery???


The alarm is just a coincidence i suspect, green light comes on and stays on probably not the battery at fault. It would be red.
If the green light goes out and screens just flash one of your screens are at fault or a loose ribbon connection.

Do i want the green light on or off on kirby upright


It has nothing to do with the green light. Green light simply indicates that brush roll is spinning. If there is no green light:
1 - belt may be broken
2 - Improperly installed nozzle
3 - wrong brush roll is installed

Properly adjust the nozzle - turn the Kirby on. Keep lowering the nozzle till it touched the carpet and you will hear change in sound. Then lower it by one more click.
