No buttons work on the tv or the remote except for the power button on the tv

This is likely to be the most comon button usedvand therefore your problem could be general wear. The construction of most remote controls are pretty simple. Remove all visible screw s and batteries and pry sides apart. Buttons are usually a single layer of rubber with a conductive pad underneath that makes contact with the pcb below. Cleaning the area on the pcb where the power button makes contact and the bottom of the rubber button, will in most cases resolve your problem, was h the rubber button sheet with soapy warm water is ok. Obviously dry throughly before putting back together.

Try changing the batteries in the remote.

I came across your post, autumlite; that's interesting! I have a few steps for you to follow to get that taken care of so you can start enjoying the convenience:

Address To Other Equipment Using Power Scan

• Remote: All Remotes (except Basic)
  1. With the desired equipment on, press and hold the correct Mode button until all mode button backlights illuminate, then release.
  2. Press and release the Power button. AUX Mode: Before pressing and releasing the Power button
     • Press 0 for a TV
     • Press 1 for a VCR/DVD
     • Press 2 for any other device
     Then Press STAR (*)
  3. Press the Up button once a second while pointing the remote at the desired equipment. Note: If the code for the equipment comes up, the equipment will power off.
  4. Press the POUND (#) button. Note: If the code entered is valid for the remote, the mode light flashes three times.

Hope that helps and let me know if you need any further assistance!

A new remote should. It could either be that the remote is broken or the receiver on the tv. Make sure that the tv works with other buttons such as volume and channel. If everything except the power button on the remote works, just get a new remote.

Press the 'Favorite' button on the remote. You may have accidentally pressed it. It locks the channel. Pressing again unlocks.

Go into the menu and turn off keylock.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:
NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet for 4 hours.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;

From GUEST: I found this solution in the manual and will perform this task again to see if I can get the tv will be re-recognized again. Give this a try, too.


Remote will not turn on or shut off the TV.
• You must program the converter box remote in order to control your TV power button.
• To program the remote control:

1. Determine if the TV is a model that can be controlled by the remote control. See "Controllable TV brands" on page 17 in the manual.
2. Turn on the TV.
3. While you press and hold TV POWER on the remote control, press CH ^ or CH v one or more times until the TV turns off. Each time you press one of these buttons, the remote control sends a manufacturer code (between 1 and 45) to the TV.

There is most likely dirt below membrane preventing contact. Remove batteries, open it up, wash rubber membrane in warm water with dish washing detergent, dry it completely. Also, use some alcohol and cotton sticks to clean contact on the remote control board.

I hope this helps, these unit were made by akai: here is the akai fix for this problem. Hold down the "F" button on the remote (top left button) and press the mute button. This should make the key go away. Thanks
