JP1 Remotes

Hi,

I have a URC 8811 that has been running an extender 3 2k for many years without issue.

Yesterday I replaced my old DVD player with a Blu-ray player, so naturally I wanted to update the remote. That's when things started to go wrong.

I have replaced components before without issue. This time I backed up my IR config and then uploaded an new config after fiddling with the Blu-ray profile in RM. The remote LED responded correctly and IR flashed twice to show that everything was okay.

Well, in fact, the remote seemed dead, except for the LED that lit up when I pushed buttons. All buttons had lost IR functionality. I then discovered that no IR signal at all was being emitted by the remote (via the digital camera test).

So, I restored my previous config through my backup. However, the remote still did not emit any IR signals!

Next, I did a full factory 981 reset. The remote reset as expected. But again, no IR signal. I programmed in a default TV code (TV button, SET, 0000, two flashes), which should work on my TV. No go. Still no IR signal at all, no matter what buttons I push.

Any ideas? What could cause this?

I did open the remote to verify that obvious connections were still intact -- though there was no reason why they shouldn't have been. Everything seemed all right.

Bottom line: no config (default or extender, factory reset or IR upload) seems to get the remote to emit an IR signal.

Any help would be greatly appreciated. Thanks in advance.

You didn't mention checking the batteries. When you push a button on the remote is the led flashing 1 time or 2 times? If its 2 times or not at all, chances are you are in a low voltage loop. I'd suggest replacing the batteries with new batteries.

If you have fresh batteries and did a restart, I'd go over and talk to wnewell in the market place. He's got a low priced 8810 that you might be able to use for parts.

Could be the IR emitter failed. No fault of yours. Just some components eventually give up I guess Sad

Try this
Disconnect any cables. Just you and the remote and the batteries.
Do a reset again
Do not do any manual programming, as the default devices will be restored and each should send a signal.
So, with no IR files,no cables, nothing in the way, press few buttons in, say, TV mode
Anything visible in the digital camera now?

If no, I'd suspect the IR emitter.
If yes, I have no idea, other than the voltage differences make no difference in what comes out. They can make an enormous difference in whether you can program the remote or download from it. At least that's what I remember from long ago.

Its sounding more and more like the remote is fried, but its pretty difficult to destroy the IR emitter.

Are you sure the camera is still working? It can still see ir from other remotes?

Did the blu-ray upgrade require a protocol? If so could you point me to the upgrade? I'd like to check that out too.

It's not unusual for IR LEDs to break loose from the circuit board and can be resoldered. The LEDs are fairly generic and can often be salvaged from old, junk remotes if you wanted to try replacing it also.

Radio Shack sells a generic 'high output' IR LED that I have used on a few projects. Look for p/n 276-143c, about 2 USD.
