Tip & How-To about Televison & Video

Your Remote Control!! Ever wonder if it is just plain Broken?

Simple Test - Look at the IR emitter thru your Cell phone camera.

Just about everyone these days has a Cell phone equipped with a camera.
If you just cant get your TV, projector, or whatever to listen to your Remote, do a simple test to know - is it really sending a signal to my gear? Ever wonder if the batteries are dead? Or maybe a button is stuck ON and draining your batteries down overnight.

Turn on your cell phone camera, simply peer at the IR eye at the very end of the remote thru the LCD screen of your camera and press any button on the Remote. You should see a light flash with each button press that you simply cannot see with the naked eye. Dont see anything? Change your batteries.
Yes, it will also work with a digital camera.

Give it a try next time your Remote makes you frustrated.

FS-4DA coin sorter won't count pennies

The good news is that the unit is functioning, it's just counting pennies. I had the same problem with quarters and is a fairly easy fix. I won't get into any disassembly details, but you'll need to gain access to the infrared detectors (mounted to the motor assembly) and possibly the emitters (mounted to the front panel LCD display/push button board). Also, please be careful not the damage the wire harnesses when removing the top cover. Once apart, you can use your cell phone camera (which is sensitive to infrared) to see a purplish/white glow from a healthy emitter. Compare the penny emitter to the others and chances are it will have a lower output level and need replacing. If the penny emitter is strong, then check the detector with any infrared remote control( TV, cable box...) by pointing the IR remote control towards the penny detector and pushing any of its control buttons. This should make the penny amount count up, and fast too, as the remote sends out IR pulses while a button is being pushed. If this test doesn't increment the penny count, then the penny detector needs replacing. But before you do, try this remote control test on another known good detector to verify your findings. Please keep in mind that other malfunctions besides an emitter and detector could be the cause of your problem, but given the FS-4DA circuitry, the odds are extremely high that you have a bad emitter 1st, then a detector 2nd, as emitters are known to degrade over time and especially when continuously powered, as in the case of a switched 'ON' FS-4DA. FYI...IR emitters and detectors can be purchased from Radio Shack. Good luck and take care not to electrocute yourself when powering the unit with its cover removed.

My Channel Plus 3445 has quit sending IR remote control signals to remote equipment. I have tried a new IR emitter. No luck. How can I troubleshoot the system or emitter?

Presumably you'd open up the remote and test it with a volt/ohm meter, but you'll need the device's schematic for that.
A quick way to ensure the remote is working: Look through the viewfinder of a camcorder while it is aimed at the remote'd emitter. You'll be able to view the IR beam to ensure that all buttons work -- and to an extent you can view the beam's strength.

My Vizio remote doesn't work...

I know that on the Logitech Harmony Remotes, sometimes the infrared LED emitters go bad. Perhaps that is what is happening to your Vizio remote. If everything was working just fine but now none of the buttons work, it is probably your issue. You can test to see if the LED(s) are working by using a digital camera (or cell phone camera). Here is link that describes how to test to see if your IR emitters are working. Although you have a different model, you may be able to pick up a few tips from this article. Good luck!

does not turn any equipment on or off. has power but does not communicate at all. I have rebooted, etc. but no luck. Old remotes still work. It appears that IR is dead.

If you have confirmed that the remote's IR emitters have failed and you are out of the warranty period (1 yr), you have a few choices. You can contact Logitech. They will usually issue a 50% discount on a new remote. Or, you can try to repair the remote yourself using the guidance in this article: http://hubpages.com/hub/HowToFixaLogitechHarmony880Remote

Or, you can have it repaired for $14 (or less if you haggle) from this Ebay seller: http://cgi.ebay.com/We-can-Repair-your-Harmony-880-Remote_W0QQitemZ200437939363QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2eab083ca3

Good luck!

the remote just seems to have worn out, only switshes on when remote is right up against tv set

There are couple things to look at here. Assuming your batteries are fresh, make sure the mirror behind your screen isnt full of dust and film. The IR has to bounce off the mirror to the IR receiver and a film covered mirror will affect that. While you are checking that, also check the IR receiver itself and dust it off. This usually sits close to the lens.
Next, to actually check the function of your remote, all you need is your cell phone. Look at your IR eye(emitter) of your remote thru your cell phone camera and hit the buttons a few times. You should see a light everytime you press a button. Cannot see this with the naked eye.
Good luck!
