I the same problem and I found that the Capacitors used on the power supply portion of the circuit board were leaking and/or bulging. These parts were failing and as a result the problem worsened with time. If you are able to remove and solder new parts on to the circuit board follow the following procedures. Or get a technician to do the repairs.

1) Make note of connections at back of TV.



2) Unplug power cord and other connectors from back of TV.
3) Remove back of TV with a Phillips (+) star shaped screw driver.
4) Note the position of all connections to the main board.





5) Remove circuit board taking care not to damage any of the components.
6) Locate parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors.





7) Remove and replace parts with capacitors of equal physical size that are (1000 uf ). I would recommend a voltage rating of 25v or 32v. Note that the voltage refers to the amount of voltage the capacitor can handle. The higher the better.






8) Reinstall and reconnect the circuit board.
9) Replace back on TV and setup the unit as before and you’re done.
10) Enjoy!

I replaced the parts for just under $10.00.

Do any experts know the answer to this question? It has been posted multiple times, but I dont' see any answers! It is a pitiful manual that is provided by Yamaha for this purpose and nothing is intuitive about making this work. If anyone know the answer, PLEASE POST IT!

The wall control is hard wired and doesn't use the receiver in the logic board which the remotes do. You most likely have a bad logic board.
