Default Sanwa RX-471W

My Sanwa RX-471W just stopped working suddenly.
There is totally no more Blue LED light any more.
Any idea what could be wrong. I did insert wrongly the Esc plug. But I google and read many comments it shouldn't cause any issues because the red line is always in the middle.
I tested input from 5.0V to 6.0V to 7.4V also the blue LED don't light up.
Look forward to some kind replies. Thanks.

You need to call or email Airtronics Tech support and see what they can tell you. Do you have a standard 4.8 or 6v nihi battery that you could plug into to it to the RX and then turn on your tx and see if the blue power led comes on if not you might of fried it or the esc could be bad to! Michael

I tested the ESC workinh with other RX-461. Workinh surely.
I also tested the RX-471W with other power supply - direct power supplies or with other ESC power supplies. Cannot bring out the blinking blue led light.

Any idea. I open and smell no foul smell. Reverse plug in shouldn't fried in because power is always the middle line right.

This is my 5th Sanwa rx. But first dead one. Some more never touch water before also (even though is waterproof).

Have you tried to re-bind the rx with the transmitter? I'd try that before I sent it in for repair. The blue led ONLY lights when the rx is bound to Tx or flashes during the binding process.
