How can I fix my converter box?

Does remote work? If you own a digital camera, use it in "video mode" to film the output of your remote control....point APEXRemote with new batteries at the video and press any buttons on remote....you should see a "lighted flash" pattern corresponding to the output or button pressed. Most new digital cameras are "IR sensitive" and detect any IR light pulsed out of most remote controls' IR LED. All use an "IR LED" which outputs infrared rather than visible light.

I use the camera on my tablet to "see" if a remote still works.

Another time, a satellite receiver I had with no replacement remote available was made to work when I re-powered the remote itself (I thought it was bad....) from an alternate source. BATTERIES alone weren't strong enough to run remote.....I used a 5v USB power adapter to run with a thin cable into battery compartment. Worked great!!! Remote needed more power, I guess.....

Suspect the remote if the power supply on APEX box is still working 100%. Otherwise, that is next thing to suspect.

THE FIX

you guys....it's the REMOTE that' the problem; not the box; it's actually pretty good quality build....BUT: the remote??? CRAP.

PROBLEM: the battery terminals get corroded quickly with that 1st crappy batteries we get when NEW (remember? no name crappy one?) and it merely won't send IR emissions `cause it ain't running anymore `cause the battery is not making contact inside battery bay. The $@$*!& REMOTE APEX USES...

TO PROVE: Use fingernail to split open remote halves. Clean; rinse; repeat. Re-assemble. Reinstall good new batteries and test. SEE?

BETTER SOLUTION: Get a good quality UNIVERSAL REMOTE and program it for "APEX" TV or VCR or TUNER (if they have)

It's same as others. Get better user interface IE: a BETTER REMOTE
