Emerson sb350 parentel control (by 2 users)

I had the same problem.I fixed it by unpluging the tv.Then while holding in the power button I plugged it back in,still holding in the power button for twenty seconds.That fixed it.I read somewhere you could reset a Sony that way so I gave it a try and it worked.I also put a cd cleaning disk in it because it was saying "wrong disk" and that fixed that problem.Good Luck
