Hi,
37mf43b/37 seems incomplete/ incorrect model number, let me know exact model number of your tv written on label pasted at rear to diagnose possible cause of problem.
Thanks.

    Most possible cause is power supply board or back light inverter boards that can be bad in this tv.
    If tv is approx 2 years old then go for power supply board and replace it to solve the issue.
    Thanks.

Same problem. The power button does not work. The volume and channel buttons turn the tv on. the tv then shuts its self off 15 seconds later. the red light blinks in second intervals while this happens.
