Repair procedure
1. Insert DVD and monitor the RF test point on the MB board (CN303/
pin 1). If there is a clear eye pattern at start up, the ARP IC806 must
be OK to support the servo system that produces this eye pattern.
The A/V decoder must be causing the dark screen. Replace the A/V
decoder IC203.
2. If RF is present but NO eye pattern is obtained at the CN303/pin 1 test
point, the servos are not functioning. If the RF is at least 1Vp-p, sus-
pect the ARP IC806.
