History :
bigla lang daw hindi nag touch
try ko mouse + OTG ayun gumagana,check version 8.1 na, so 1st option ko is flash boot files repair touch screen

Solutions :
#1 flash Boot file Touch Repair then format data/reformat > failed, kaya i decide to open ang unit
#2 Open ang unit,may nakita ako corroded na parts,see pic below,try ko linisin then wala pa din response
hiniram ko muna ke pareng google ang image

#3 tapos linisin,not responsive pa din ang touch screen,kaya i decide to try and change ang LCD, mapa CLASS A man o ORIG eh wala gumana,not responsive pa din
#4 my last option muntik na maRTO ,silip muna sa microscope,then kita ko wala na "CONTACT" o PAA yung kabilang side ng CAPACITOR,see pic below
kaya tinanggal ko na
ang salarin
