My unit is displaying W OPE. It is not responding to the remote for poweron/off or anything else. The screen is indicating that a disc may not have recorded correctly (I was not trying to record anything) and wants me to press the OK button but it doesn't respond to it. I have tried unplugging the unit and it always comes back to the same message. I have the panasonic Blu Ray player model number BTT273.

SOURCE: Can't get sound from the wireless subwoofer

I had the same problem and it turned out that the directions are very unclear. You need to not only press the ID/SET button on the wireless system, but also on the wireless subwoofer itself. That solved my problem.

SOURCE: Doesn't respond to any commands

condensation has formed wait for 1 to 2 hours to evaporate.
the unit can not play discs other than who listed in operation instruction.

Hello Pamaral,
I have seen this problem a few times on the panasonic models and for some reason they fail quicker than they should. If your system is still under warranty you should send it in for service. If it is not, it would probably be a bit cheaper to go to a local repair shop and get an estimate as to the cost of replacing the defective IR sensor rather than sending it to panasonic where you will have to pay shipping and handling charges plus their parts and labor (which is like taking your car to a dealership for repairs and much more expensive than a local repair shop). Hope this helps and let me know if you need further assistance.

I figured out, unlike all the other posts, you don't have an enter button. But Instead, you would hit the 2 and OK button at the same time for a few seconds. I had the RC1 message and I did the 1 with OK and it worked. so if you have RC2, you should hit the 2 and OK. Should work!!
