Element ELCHW321 Wacky Function Control

[kevinm34232]

Got this TV with no remote. Powers up and works. Buttons on side of TV don't work correctly, menu keeps popping up no matter what you press except power.

Programmed a universal remote and can get things to happen but menu keeps popping up in between every function.

Opened up TV and unplugged the key board controller from main board and the remote control works normally.

Is this just something wrong with the keyboard controller board or could it be the main board?

Probably a stuck menu button on the key controller or a bad controller. They are usually cheap on ebay, if you can find one.

They are available but the button does not seem to be stuck and checked it with ohmeter. There is nothing really to it but a few push button switches, a few SMD resistors and 2 SMD caps. This is why I thought maybe the main board. There is also an EEPROM chip available but not sure if that would cause this issue.

what if you cut the wires to the menu switch and hook up a micro switch to eliminate the actual switch. if it works, change out the gang of switches and if it doesn't, just reattach the wiring that you have tapped into.

You guys were right it was a bad keyboard/button control board, I replaced with a new one for $10 and it works fine.

I guess even though the switches tested good it must have been intermittently opening and closing!
