Thanks for this draconian suggestion! Lol.
See, this problem happens at random, and might recur two weeks apart, or, t wo months apart. Relatively infrequently.
The remotes involved are for my 32" Sanyo flat tube TV, and my JVC VHS/DVD combo deck. Both are ten years old but are in fine shape and work flawlessl y(aside from this weird remote problem).
The JVC combo remote can also be programmed for basic on/off, channel, and volume of a television. It is thusly programmed to control those functions of the Sanyo.
The typical scenario: I pick up the Sanyo TV remote to adjust the volume, press volume up or down, and nothing happens. I press harder, and the volu me just races away - up or or down. I then must run over to the TV and pre ss the volume buttons to stop it.
Ditto the volume buttons on the JVC remote. And they both behave this way at the SAME time. The episode typically lasts minutes, and in a half-hour both remotes' volumes operate normally. And it may not happen again for another week or even months.
