Hi James,

Yeah, I was a technician for approximately 4 years but that was over 7 years
ago and haven't been in the industry since.
Thanks for the advice and the warning, problem is I don't have the original
remote so I'm not sure how I'm going to follow your instructions.
I have a universal remote I could probably use but I'm not sure how that
will work since there is no was of working out which key will end up being
the "Display" key. I might just have to try all the buttons and hope one
works, but I sense that might end up being a disaster. Does this process of
pressing the "Display" key, while pin 2 and 7 are shorted, in some way
reprogram the EEPROM?

I don't know what to make of this problem, EEPROM's were seldom found in
TV's back in the days I worked on them.

Thanks again,

John.
