Usually, the U11 error code in a Panasonic DVD player indicates an optical problem. You could of course try doing a cleaning using a CD cleaner normally readily from computer parts stores. Alternately, you can open the unit up and do a manual cleaning with soft bristle brush and/or cotton buds. Other than that, it could be indicative of a weakening laser eye which of course would require parts replacement.
Hope this be of initial help/idea. Pls post back how things turned up or should you

Eventually the front panel display will show "SERV" (after its "HELLO" messages). Anyway, pressing  then  on the Remote Control tells me that I have an Error Code of "04" which is a Digital PCB or Communication Error (whereas an Error code of "02" means a "Defect of RAM drive"). (To exit from Service Mode, press  then  which should get you back to "SERV" and then POWER-OFF the machine). Hopefully, your manual will display your error codes.
Perhaps the remote control is not set to the same control code as your DMR-ES40V. Codes may be set to 1, 2, or 3 on the remote by holding down the enter button and one of those number buttons for several seconds at the same time. The factory default is code 1. Try 1 first. If that doesn't work try 2. If that doesn't work try 3. If one of those codes doesn't work you may have a bad remote or a bad sensor on your machine. On DMR-ES35V models the sensor is located just to the right of center behind the black window
Reset the unit as follows:
Press [POWER í/I] on the main unit to switch the unit to standby.
If the unit doesn’t switch to standby, press and hold [POWER í/I] on the main unit for about
10 seconds. The unit is forcibly switched to standby.
Alternatively, disconnect the AC power supply cord, wait one minute, then reconnect it
I'm pretty sure the force disk eject is the same across all Panasonic models - however I couldn't find anything specific for your model number. Still worth a shot, though.
With the unit in standby, press and hold the 'Stop' and 'Ch up' buttons together. It should power up and force the tray open. If this doesn't work, try changing up your timing by pressing and holding 'Stop' first, then a half-second later, press and hold 'Ch up' and keep them both held together. You can also try the opposite.
If none of these work, it will have to be taken apart to get the disc out. If you aren't comfortable trying, it will have to go to service.
