Clean the keypad contacts (both sides), maybe some contact is in short circuit.
Look for water damage.
Key # is ROW4-COL4 and PWR key is connected with ROW4.
May be volume keys problem, they are connected with COL4.
Check/replace: R371, R372, R373, C371, C372, C373, S300, S301, V360, R374, C342, S330
