I have a Sony KV20s42 tv that has sticky buttons.
When i press + volume, the channel will go up(channel +). Both buttons
are next to each other.
I am pretty sure it is the buttons and i would like to take the board
out and clean the buttons.

Question: Is it easy to remove the board?I already got the service
manual.
