Facing TV Problems? Ask a TV Technician.
Hello , I`m Jack
Perhaps I can help you with this but first I have to say that there is no way to bypass or disable this parental lock without the TV's original remote .
Here is your original remote ; http://www.remoteyard.com/mitsubishi-remote-290p035010-cs27405-cs31203.html
Let me know when you see this and I will tell you how its done with the remote
Sorry but there are no miracle to be performed without the remote and if you already know how to unlock the tv then you should know the remote is needed and that is it.
