How do you fix the button on and MX-850 remote control

On the MX 3000 I don't believe there is a manual volume control. Sorry. Can you source a remote? A universal remote such as 3 in 1, may work.

go to www.remotecodelis.com or memorex.com

God bless you

take the batteries out for a few minutes and put em back in. Sounds like a glitch. Cutting the power should reset its functions.

What kind of receiver did you get? DirecTV, Dish, or something else? This remote comes with software and cables you can connect to your computer. Once you install it, and connect the device, you can program it to connect with your specific electronic components. You may need your existing/original remotes to help get everything set up, but usually that is a one-time process.

Replace the button or the plates beneath them

You need to do an update from your version by clicking HELP from the application's menu bar, then select LIVE UPDATE.
...of course, you need internet access.

173 or 193 is for a directv box. It may be manufactured by another company, hughs net, rca, ect.

you might want to reprogram it with different codes. it's a classic problem.

i have the back off my Aeros MX 850 remote and need to fix a part that came off and was sitting inside on the Circuit card. It has a spring attached to it but I can't find the location of where it goes. Need to find a schematic of something. Please help. No TV in the house now
