LA7688 DAN LA7687

kemarin ada rekan servis yang menanyakan
apakah LA7687 bisa diganti dengan LA 7688
pada tv SANYO,dengan sangat menyesal kami jawab
tidak tahu ???..karena kami sendiri belum pernah
mengkanibalkan ic tersebut,dan barangkali ada diantara
rekan-rekan yang sudah pernah mencobanya tolong dong!!!
