This unit reverts to the home theater mode after a power failure. When power is restored the input button will only access tuners A & B and has sound but no picture. If I go to the AV connection menu, the LOCK TO INPUT 1 sub menu says YES, upon changing it to NO the set resumes normal operation but has Input 4 installed, this set has no Input 4. I can go to the service menu and remove input 4 but after a power failure it returns. Are there option bytes in the service menu that may have changed (and if so how do I change them back) causing my trouble or am I looking at an eprom failure. The only info I have on this set is a simple sheet of access codes to enter the service menu.
