Still troubleshooting pa din po boss..nasa akin pa unit, matagalan ako nito kasi need pa painitin ang tv bago makita ang problema. Change mobo ko na to pag nainip si tomer. Salamat po.
 
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.
