insignia ns-55l260a13 buttons not working

[Eel_dahc]

Hello everyone.

I bought a used insignia ns-55l260a13 that they said didn't work. It was $20. But it does work as I turned it on and left it on for an hour. The only thing that I found that's a problem is that one volume, one menu and one other button don't work. I took out the button board and cleaned that up as one button for sure wasn't working. After cleaning they seemed fine with the meter. Then I noticed a short, with the button board unplugged between KEY1 and ground on the connector so I followed the trace until I found a cap (red dot) that seems shorted.

Do you think I would be safe just popping that off and see how it goes? I'm not a pro at this.

Well, remove the suspect cap and see if the shorts will go away or not, if it does then use the cap meter then you check the capacitance of the cap to the right after removing it to test the capacitance.

Took the cap out and a resistor that seemed shorted too. Those weren't it and the traces then ran under the metal shielding to one of the processors so I stopped there and just put it back together. It works with a remote. Thanks Budm
