nacheck mo na ba ang mga peripheral parts na nakapaligid sa tuner sis..baka may weak na ecaps or change value na resistor..OR try mo inject nang signal sa loob ng tuner baka sakali gumana..

agree ako sa inyo mga master. nakasubok din ako ng ganyan. may sirang ceramic capacitor pala malapit sa jungle. may iba naman na hindi pala compatible lahat ng tuner kahit pareho ang pin arrange.

dapat may reading ka nga dyan. kong duda ka sa scl  at sda na nagmumula sa system ay maaaring system mo nga may problema. kong gusto mo gawing analog from digital yan o maging manual ang pag tune ng channel. Hanapin mo lang ang VT pin ng tuner module niya at lagyan mo ng potentiometer to ground. bawat pagpihit ay mababago dapat ang channel na naaayon sa resistance value niya.

para malaman mong kung gumagana ba talaga ang tuner mo at sa digital controls ka lang may problema. Digital ctrl means thru osd at command line ng system ang magko control ng VT

depende sa pagkakasira niya. kong VT control lang ang error command ay magkakasignal ka nga dyan. 10K hanggang 50K ay puede dyan.
