Baka po grounded ang volume buttons. Try po gamitan tester.
 
Naayos po ba? Kung naayos ano po solution and update po please. Thanks
 
Problem solve po. Change R82 10k resistor to 1.3k kasi low dc supply ang mga keys nya, supply must not drop 3v each. Track dc line kung san sya nag drop, sa case ko naging 2.6v nalang ang supply ng vol+ at vol-.
Tips: when troubleshooting this kind of problem, it is more effective when tv is power on. Just be very carefull.
