Back in another lifetime I sold a customer the above VCR/TV combo. He called me today. It's developed a programming bug.
Starting a day or two ago, when he uses his Beolink 5000 remote to step up or down to the next cable channel, instead the TV goes to a black screen and says "device". If he uses the "go to" button, he can direct access a station, but he can't step to it any more.
He doesn't have the manuals. I don't have the support material, either. Any ideas of what got messed up and how to re-program the system to correct it?
