By that - I mean sometimes my TV (yes-this a little off-topic) doesn't respond to the remote. I have 3 remotes specific to the TV - and a universal remote. It is a 9 year old TV/VCR/DVD combo. Toshiba. For 8 years - no problems whatsover. Recently - once every few weeks - the TV stops responding to the remote (you can still operate the TV manually) then after a few hours - the problem fixes itself - and the remote works fine. Does anybody know what causes this?
