FRONT PANEL BUTTONS NOT WORKING - BenQ FP72E 17" LCD Monitor

Does the remote work the functions that correspond to the front panel buttons? The front panel board could be faulty. you should get it checked by a technician.

Had same problem but solution was different. Start button looked slightly misaligned and wouldn't always work. Followed instructions to pull off front control panel, removed LED display panel and the plastic tab that the start button was attached to had broken off from the panel. Used a good epoxy to glue the edges back together and it works like new. Also broke two tabs that hold the LED panel inside the front plate due to the plastic becoming brittle. Again, epoxy is your friend. Works like new.

If all other buttons at its front panel works, except the menu button, check and replace the micro-switch to it. You have to open the TV to access it, and can be located at the front panel control board.

There are two main pieces to the front panel for the GFDN240EL1WW dryer-- the plastic panel and the circuit board. The actual replacement part is: Control Panel WE19M1687. The panel can be purchased for from places like partselect.com or repairclinic.com or Amazon or even EBay, etc. for $100-$200+.

The power button is just a piece of plastic mounted to another piece of plastic; it is not electronic. When pushed, it presses against the circuit board, which then turns the unit on/off. When the power button breaks, it typically means the little plastic button has broken off from the plastic panel. Most likely, the problem is the mount point for the button and the button is actually re-usable.

A cheaper quick-fix is to:

• Remove top screw from back of the front panel
• Remove main front knob from the panel
• Remove screw from behind the front knob
• Grab both sides of the front panel and push/pull up to remove the panel
• Disconnect the block connector (power) from the circuit board after removing the panel
• Locate the power button and mounting position
• Inspect to see if it looks like you can glue the button back into place
• Buy a small tube of loctite Stik'n Seal Ultra Universal Adhesive
• Put some Stik'n Seal on the button mounting point for the power button (be generous)
• Press the button onto the mounting point and hold for a few minutes
• Add more Stik'n Seal around the edges of the mounting point and the button mount after you have held the button in place long enough so that it sticks
• Let the whole thing dry for several hours (instructions on the adhesive say 24hrs
• If you are worried about the button staying seated while the adhesive sets, you can always try tape it into place
• When dry, replace the front panel by reversing the steps above used to remove the panel: connect the power block, slide the panel back into place, replace the front screw and knob, replace the top screw in the back of the panel

Try resetting it. Remove front panel, on main unit is an indent that says reset, insert ballpoint to reset and replace front panel. Everything should now work although you will need to reset stations and clock.

After several power ups, the front panel buttons eventually "woke up". Replaced remote, and everything's working fine. Not sure why the front panel was temporarily unresponsive.

To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds

The following solution has been posted in another forum (www.hometheaterspot.com) and it fixed my remote problem:

"...it's possible that one of the front panel buttons is "stuck" or shorted, and this could cause the TV to ignore commands from the front panel or remote. But this should also cause the Power command to be ignored, too. You might try pulling off the front panel and disconnecting the front panel buttons and then see if the remote works."

Have you checked whether the front panel of your reciever hinges down or up if it does there may be a cut off button under there which when operated will let the front panel buttons work again

The first unit might have a broken or crack front panel,is possible since it was purchased new,it will be a good idea to remove the top cover and try to see if something is broken in the front,you can also remove the front and have a better look.Let Us know how it goes,make sure the unit is not plug in if you try it.
