Sony Trinitron TV not accepting IR remote control

[[email protected]]

I have a 27" Trinitron that has been working great for years (6-7yrs
old??).
5 days ago I noticed it would stop accepting commands from the remote.
Over the pat 5 day I have figured out its pattern:
If left setting (on or off) for a good 10-20 minutes, it will accept
about 9 or 10 commands from the remote, then it stops. You then must
wait aporx 8 seconds before it will accept another command. If you try
to give a command within this 8 seconds, you have to wait even longer,
like 15 seconds, before it will accept again.
If I give it about a full minute, it will accept 2 commands before
stopping again.
The TV being on or off makes no difference in these times. If turned
off with the remote, you cannot turn it back on with the remote unless
you wait the ~8 seconds!

It is not the remote or batteries. I have tried two different Sony
remotes (one is brand new), and gobs of batteries, they all do exactly
the same thing. I have also held the remote directly up to the IR port
on the TV, and still no change.
The buttons on the front of the TV work fine.

It is very weird how consistent the pattern above is.. any ideas?
Using a 10' stick to punch the buttons on the front of the TV is not
really an option.

I have only found one post about this exact symptom, and his solution
was to turn the batteries around in the remote. I have to say this will
do NOTHING since if you turn the batteries around they will not make
contact in the remote, and is the same as just taking the batteries out
(which has not fixed it. :-/ ).

Thanks-

I had an uncle who was really healthy and well for years, right up to
the moment he died.

Accept it. It's dying. The next 2-3 years the CRT will age a lot. It'll
be one thing after another as the components start to die. Get a new or
newer TV. have you seen what kind of CRT TV you can get nowadays for
not much money? Your eyes may be used to a well-aged tube, take a look
at some new ones in modern sets.

New batteries?

If you rotate the batteries with your finger, that can clean up the
oxidation on the contacts just enough to get a tiny trickle of current
from nearly dead batteries. My Sony still had the original 1999
batteries that came with the remote, when i tossed it 3 weeks ago. I
rotated them about 3 years ago and they lasted the rest of the set's
life.

Probably a bad solder joint in the IR receiver inside the TV, or a bad
component inside the IR circuit. Don´t waste your time with new
batteries or remotes, because you alreade stablished that the problem
is with the TV.

A competent technician should be able to fix your TV without much
trouble. If you like your TV and the image it produced, just repair it.
No one toss a TV because a simple fault like yours.
