1. Device: Emerson EWL20S5
2. Type of device:TV
3. Year: 2006
4. JP1/UEI Remote model: URC ) 8810B00
5. Do you have a JP1 cable? yes
6. Still have original remote? no

While a normal universal remote could be used to control this set I need to put it in the factory setup mode by shorting a jumper inside the back of the remote so that I can get into the setup menu but the original remote (with a jumper inside the back) is not available. Is there any way to do that with a JP1, program it for setup mode?

[The Robman]

When you short the jumper in the original remote, you change the signals sent by the remote, the question is, what are the changes? We can replicate just about anything with a JP1 remote, but we would need to know what changes were caused by that jumper in order to tell you how to make your JP1 remote do the same thing.

Try searching the net to see if you can find any documentation about the service menu codes, because if you can find them in any format, we can probably figure out the JP1 codes from that.

Are you able to control the basic functions of the TV today? If so, what setup code are you using? If the service menu codes use the same protocol and device code(s) as the basic functions, you might be able to find them by trying unused EFCs.

The original remote that came with the Emerson EWL20S5 was a NE900UD. This remote came with the following TVs and models:
EMERSON
EWL2005
EWL20S5
EWL20S5A
EWL20S5B
EWL20S5C
SYLVANIA
6615LF
6615LF4
6615LFP
6615LG
6615LGA
6620LF
6620LF4
6620LFP
6620LG
6620LGA
CSL1505
SSL2006
SYMPHONIC
CSTL1505
CSTL1506
CSTL2006
STL1505
STL1505A
WF20L6
FVD2678

You can pick one of these up on ebay for about $15-$20 if its worth it to you to have one to play with.

I see different remotes on ebay claiming to be a NE900UD, so some of them are generic replacements. Therefore, I would check with the seller that the remote has the jumper pins before buying.

So far the only thing I've been able to determine is that code #10171 will operate the TV using my Directv RC64 remote. I found a copy of the service manual online that tells how to get into the setup mode by soldering the jumper on the board in the back of the remote but no codes or anything. I'm pretty sure none of the ebay sellers would be able to tell me if their remote has provision for a jumper in the back. I doubt if any of them can even tell if it's the original remote or if it works with the EWL20S5.
Is there any way to tell what JP1 codes to use for setup if I know it uses 10171 on the RC64?

While I don't have the RC64 in my remote database, the Lookup Tool shows that the setup 0171 code in your 8810 sends an Emerson 41 signal. Since this is an Emerson TV, I'm pretty sure that this is the code that you are looking for.

When you short the jumper in the original remote, you change the signals sent by the remote, the question is, what are the changes? We can replicate just about anything with a JP1 remote, but we would need to know what changes were caused by that jumper in order to tell you how to make your JP1 remote do the same thing.

As Rob said we don't know what kind of changes the jumper makes to the codes sent.

If the service menu codes use the same protocol and device code(s) as the basic functions, you might be able to find them by trying unused EFCs.

It's quite common to end up in the service menu when exploring EFC's so this is a pretty good guess but its not a guarantee as the the jumper change could have changed just about anything from the device number to the protocol being sent. However I did find other people talking about the service menu being on a "hidden button" and they are cutting holes in the remote, so its a really good guess that this would be another button in the 256 possibilities.

You might want to start with by exploring EFC's that are not in use here. Select Emerson 3 dev combo and find the EFC's for missing OBCs.

Thanks for the info. What I really want to do is Initialize the set to restore default values since it seems to have some bad setting that cause the picture to not display properly and the top half folds over the bottom half. The manual says to make a service mode remote by soldering a jumper across J1 in the back but that requires a N0105UD or N0127UD remote. Then you press Power and Sleep to get into the service mode and then press Display to Initialize it. So it looks like I would have to try all the values between 001 and 999 that aren't already used for something?

1 to 256.

This is just a guess. We're hoping its just a missing button in the sequence, but it really could be anything. Ideally someone with a OEM remote could test this out for us, but since that hasn't happened, testing the missing OBC's seem to be the best guess.

[The Robman]

The actual range is 0 thru 255 (but they wrap around so 1 thru 256 would also work).

The trick will be recognizing when a button does something, as some buttons might require the set to already be in a certain state.
