I need the remote code from a Viewsonic N2750W LCD to program my remote for my Bell Expressvu PVR 5800

SOURCE: remote controle code

There are some codes for Viewsonic tv's but apparently it's really hard to program and the codes even change. I read somewhere once that the best way to program it is to try with those really expensive remotes that can program everything, but you will need to contact viewsonic for the software to upload to that remote.

Could be a problem with the down volume button on the tv. the board it's on ir its harness. Check them all. Make sure the volume buttons plastic actuator moves freely and is not stuck.

If these parts are all good, you have a problem on the main board. You may have to trace the control lines as far as you can and check any capacitors along the way. If you have an oscilliscope you can test the lines to see if the up volume is working correctly. If there is noise on it, you might find a bad capacitor if you can trace it back far enough. Schematic helps here.

Of course, make sure nothing is shining on the sensor window on the TV. You might want to scope that line as well (IR sensor line).

If none of that helps, get hold of Viewsonic and find your closest service provider. You can order a main board from them.

Of course, you could try just using the audio out jacks to an amplifier or a surround sound amplifer. Then you would use the remotecontrol for the surround sound system to control your volume.
Bet you were going to buy one anyway right?

The easiest way is to do device code scan. Since you want to program the TV, hold the TV button on your bell expressvu remote. When all the top buttons light up, press the power button, the TV button light should remain lit. Keep pressing up/down until your TV turns off. When your TV turns off, press the # button. Thats all. Your done.

If you want to set up the AUX button, hold the AUX button until all the buttons light up. Then press * and either

0 - second TV
1 - second VCR/DVD player
2 - audio amplifier or cable box

Then press the power button and press up/down until the device turns off. The last step is to press # and your done.

I had the same problem with a Viewsonic N3735W LCD TV and Comcast Customer DVR 3 Device remote. I contacted Viewsonic and they gave me 11454 which works.
