Well, that started to happen when the remote was not old, and several
years later I'm still using that machine. It is my only device that
developed that problem. I have (had, I threw them away this summer) TVs
older than that.
 
No one sells that ancient remote control AFAIK.

On ebay I found someone who sells universale remotes that he has
programmed for specific devices. They aren't univesal anymore and they
don't come with instructions how to make them universal or any other
model. I think I found it just by googling the model number, but on ebay
where I didn't expect them.
 
One time I think he wrote me that he was going to stop because he was't
making enough money anymore. I said Raise your price. He still would
have been cheaper then new old stock. (It occurs to me now that I only
know about my particular make and model, and I presume he sold many
different models.) I don't know what he decided to do. He had one
location in the USA and one in England, I think it was.

This particular machine is a very good design, but will be made obsolete
soon, if they mandate digital TV to be all in HD (it was scheduled for
this year, I think). My device can't do HD. And the aerial reception in
this room is bad.
 
It is a double tuner for terrestrial digital TV. It can use a shared
folder in a Linux or Windows computer for storage, or connect to an
external, USB2 hard disk. It is capable of making two simultaneous
recordings while playing from disk another program. It can be managed
via a mini web server, once it is flashed with community software
instead of the original one. It is, or was, really good. Except for the
remote.
 
I manage it via network, I almost never use the remote control.
 
I only mentioned it as an example of devices that work badly with a remote.

Good to know, thanks.
 
I wonder, if someone could publish libraries of codes to teach remotes
the "language" of some other remote in the library. Would save effort
and time.

I wonder if that is the degradation process that happens to kitchen
utensils, that have parts made in some kind of non slippery rubber.
After some years, they degrade and leak something like a glue and have
to be thrown to the garbage, unless the rubber part can be removed and
the thing still works.
 
It is not, apparently, what happened to my remote, as the buttons are
still, apparently, intact.

The now discontinued Logitech Harmony remotes have a very extensive list
of supported devices on the support website. They claim they will
continue support. I bought a couple used ones off Ebay for $10-15 and
love their capabilities. The ones with screens will usually offer access
to all the functions of the original remote without having to learn them
from the original remote.

I had a snap-op screwdriver that had that happen to the black plastic
handle. It would just get sticky gooey crud all over it and leave a
puddle under it in the drawer. I stopped by a snap-on truck one day with
it, and he gave me a new "better" screwdriver in exchange.

I am disappointed with their reliability. I maintain the lights in my bloc of flats and the lift lights years ago used CFL GU10 type bulbs. They were rated a lifetime of 20000h which are 2.5 years as they are always on and they actually lasted about 3.5 years.
 
Three years ago I installed GU10 led bulbs with a rated lifetime of 50000h, that's 6 years! After two years both bulbs failed with blinking lights. They did not even reach the rated lifetime of CFL. I also see many TV led backlights fail more often than CFL. For now I consider CFL quite more reliable than led.

You may be right. I've had good life from CFLs, even stopped writing the date on the base.
 
I haven't had an Led tube fail, but have had a couple of bulbs burn out. Still most are going strong. Might it depend on how the fixtures trap heat?
 
I've yet to see a traffic light where all the leds work.

The Chunghop L336 universal learning remotes work well and are cheap
enough. All buttons programmable and remembered even if battery goes
flat. BUT - you do have to have a working unit to learn from even if its
