JVC AV-21D31 raster only/ AV input ok
« on: November 23, 2011, 12:53:05 PM »
mga master pa tulong sa JVC AV-21D31, Raster only pg-naka channel pero sa AV input ok

try ko muna auto program ng channel bago ko buksan yun unit pero after wala pa rin!

check ko voltahe sa tuner 32v, 5v & 9v ok naman!

 pull out ko ang tuner test ko sa ibang unit ok sya meron channel!
