JP1 Remotes

Thanks for all your valuable advice. I'm going to do the factory reset but in case that doesn´t work, well, I'm going to tell store where I bought it if they can fix it.

Or, is it difficult to replace and solder such part?

I recently bought this remote but the lite button seems not to be working anymore.

I pressed it once and it, indeed, lit the remote but after that, it won't.

The remote was handled gently with no falls before or after that. I guess I maybe changed a code secuence and that is making the lite ...
