Opening the MX-500 Remote Control

Buy a new one, or if you can open it, you could try to clean the printed circuit board and the rubber part, where the buttons are on. If it was normal water, drying it and cleaning both sides, with a dry cloth, even if everything is already dry, should be enough. If something like sugar was in it (spilled some soda drink) please first try you get of the sugar, with clean water from everything. (When it is open) and dry it carefully, Check all contacts are clean and nothing is on it. The black parts under the buttons, should stay on there, because the resistance is needed to make the contact on the circuit board.
Perhaps you can find how to open your remote, on ifixit dot com.

MX-500 manual

Hi Robert,
Most of these remotes are carbon pattern type closed switches. If you cleaned the PCB with other than a real pure solution like rubbing alcohol the pad may still be shorted continuously. The real problem is that if the button were sticking that usually mean there was a contaminant inside the remote which could be a drink or other spill. All that needs to be cleaned out. I use denatured alcohol but I do not scrub the carbon traces as they can be removed if not careful. A light cleaning with Windex might help as drinks are water based not alcohol based. I could take a look at the remote if you want. I repaired a number of them when I was Sony authorized and working at other places as a Chief Engineer. People seem to bring me things to repair- it is still going on but most cassette decks and Open Reel decks now.

Hello
Pre programmed codes with MX-500 to JVC are
240 163 191 114 266 279 291
OK

If water was spilled in it, the batteries should have been removed immediately, if you could remove the circuit board from the casing, dry it off and place it under a lamp for a few hours it should have been perfectly fine. If a soft drink, sugar base or other substance was spilled in it; the board would need to be cleaned, a small amount of soap and water can work, use a cotton swab, only clean the affected area of the spill, make sure to rinse all the soap off, dry with towel, then place under a lamp to get all the moisture out. Also make sure you clean the bottom side of the buttons that contact the circuit board. If it doesn't work then you may have to buy another unit.

If you have a MX-500 use your origional remote to teach the MX-500 the codes.

If you have a learning universal remote, such as the MX-500, just put the remote in learning mode, press the button on the universal remote you want to program then press the appropriate button on the other remote. Otherwise, we'll need to know also what remote control you have. They are not all alike.

I had several batteries that I ordered and they have been all purchased. Since I make no money on the batteries and can only order in bulk I will only order them if I can round up over 50 customers who need MX-3000 batteries. If you need one, please go to www.totalcontrolremotes.com and get in touch with us by putting "MX-3000 battery needed" and we will add you to the list. Either way wil let you know by mid-March 09 if and when the order will be placed for additional batteries.
