SOURCE: toshiba 32av615db tv - keeps scrolling channels

On the back of the TV, where the main board is (the one with many AV inputs to it) there are several cables going into it.

Find the one that leads to the buttons on the TV - it won't be too hard to trace - and after turning on the TV disconnect that cable.

Or, if the cables for the buttons and the front LED and IR sensor are separate (sometimes they are) you disconnect the one for the buttons and then turn the TV on with the remote.

Either way, see if the problem persists with the buttons panel disconnected.

if it does then the problem is in the main board and likely you'll want it replaced. The way they make them these days it's really cheaper to replace the whole thing than to look for a problem among components the largest of which is about a millimeter long.

if the problem is in the button/cable'll probably find it easy. Often it's because that same cable has been trapped between the front and back covers and broken or shorted by the friction and pressure.

Hope this helps....would appreciate a review on Google if it does!

Whats the code for my LG soundbar for my one for all urc 7140

3217 if you have the 2013 version of the remote (URC 7140 R003).

If yours is older, then the specific code isn't in the remote's memory. OneForAll suggests you contact their customer service number. It's in the user manual. They might be able to suggest an alternative code for an older soundbar that works just as well.
