As soon as the power is applied, the green led starts blinking continuously. No remote control and any operational switch works.

If the green LED keeps blinking after it's normal 8 to 10 blinks at power-on, you've got a faulty A-Board (main board).

True, The A board is faulty but is it possible to repair A board?

Thanks

A very complex board which I've never attempted to repair. Have always gone for replacement, but they're
very expensive.

Good feedback, I'll have to remember that for next time I get one behaving thus.
