Remote works ... I have changed the batteries ... no help ... sound increases but will not decrease, channels will change up but not down. TV is a ViewSonic N2751w ... controls are on the top ... they work up and down, both volume and channels ... can you advise regarding the remote? ... unit is dated April 2006
Okay here's the fix. Remove batteries. Re-install them wrong side in! Don't panic. Reverse the direction of both the battery cells and install. Press "Power" button a couple of times and a few other buttons a few times. Then remove batteries and re-install the right side in. Voila.
I solved it...After weeks of suffering,(you know how it feels without the RC). Solution: On/Off switch Press Power button & Info button the same time to toggle on/off Volume(reduction): Press Vol"-" & the "down"(inverted triangle button) the same time

Re: viewsonic remote RC00070P
Many times on old remotes, dirt accumulates on the inside or just some particles get into the inside of the remote and the buttons will not make contact. I have repaired this remote as well as others by cleaning. First the remote has to be opened, and this is the hard part. It is snap fit together and you have to work a screwdriver or other sharp object into the side between the halves. There are no screws used in this remote. I put a screwdriver into the only opening I could find - the LED at the end and accidentally pushed one of the LED (the clear bulb) leads off the circuit board that I then needed to resolder. After the remote is apart, just pop off the circuit board and clean the side of the board that makes contact with the buttons and then the backsides of all the buttons with rubbing alcohol (clean the button fronts if you like to look at clean buttons). Make sure both leads to the LED are soldered. On my remote, a small piece of dirt came out. Reverse the process to reassemble.
We installed a new adapter on a Comcast service for my 2nd TV in our bedroom.. Their remote is not in sync with our Viewsonic so I've to use the VS-remote. At first, power button was working, then it died out. Changed the batteries, the power still didn't work. I read the instructions here to install batteries in reverse and tried the buttons, of course it won't operate. I put them back again in proper sequence "voila great idea Amigo" . It worked and I can operate the power button again.
One day, my report stopped working. I couldn't turn on the tv, change channels, or change the volume. I changed the batteries twice. I then pulled out the batteries for 5 minutes and put them back in. It worked! Thanks for the solution.

I had come home about a week ago and pushed the power button from my
remote but my tv did not respond. So I just went to the front panel and
pushed power but once the tv turned on, the volume was on full blast! I
used the front panel volume decrease to get the volume down, but when I
stopped pushing the button, the tv increased its volume to full blast
again by itself! Naturally I just turned the tv off for a few moments. I
tried the remote again, no response again, so I used the panel power
button. The tv volume was still full blast when it turned on but after I
decreased the volume it stayed this time. The picture is and has been
perfectly fine and the tv was working fine. The next day the problem
started all over and now once we turned it off from frustration of
having to manually use the panel to change channels, it now will not
turn on at all. I have changed batteries from my remote, reprogrammed my
remote, pushed system reset several times, unplugged it for a while,
bought a new surge charge, and even held the menu and device panel
buttons for 10 sec and tried to turn the t.v. on again! What other
options do I have or what may be the issue at hand and possible parts
that may need to be replaced?? Thanks!!
Your description suggests bad/dirty contacts inside the remotes and jammed volume buttons on one of them. Cleaning the rubber pads and the circuit boards on all of the remotes might solve the problem.
Use some ethyl or isopropyl alcohol and cottonwool to clean them.
By the way, here's a nice way to test a remote using your mobile phone's camera:
Turn the camera on, point the remote towards the camera lens so you can see it on the mobile's display.
Look at the display on your mobile phone and press buttons on your remote - you should see bluish/greenish flashes from your remote's emmiter each time you press a button on the remote (the camera on your mobile shows infrared light from the remote as visible light on the display - if it doesn't do so in the normal mode, try the night mode for the camera instead).
If you press a button and there are no flashes, that button probably has a bad/dirty contact.
if the remote is making flashes even when the buttons are released, this means that a button is jammed (you need to clean the rubber pads and the housing, especially the holes where the buttons come through as there's probably some dirt that keeps the button pressed in, which causes the volume to go up/down all by itself).
1. Manually turn on the device (TV, VCR, etc.) to be controlled.
2. Press and hold Code Search button until the red indicator stays on. Release the Code Search button.
3. Press and release the desired mode button (TV, VCR, etc.). The red indicator blink, then stays lit.
Press the Channel Up button repeatedly (up to 300 times) until the
device could be controlled changes channel. The red indicator blinks,
then stays lit. If you accidentally overshoot the code required, press
the Channel Down button to backtrack through the library until the
device changes channel. Pressing Channel Up changes direction to forward again. Press and release the Mute button to install the code.
