Fourth Generation DVD

Symptom 2:
1. Goes to Standby (red light) after powering ON.
2. Goes to Standby (red light) while playing a disc.
Cause: Syscon IC102 failure or there is nothing wrong.
Repair Procedure
1. First press the front panel power button. The power light should change
from red (standby) to green (ON), then back to red. (No light
⇒ ⇒
light green light red light). While the red light (standby) is ON,
press either the PLAY or TRAY OPEN/CLOSE button. If the unit pow-
ers ON again there is nothing wrong with the unit. This is normal. The
unit entered the standby state after pressing the latching front panel
power switch. Think of the front panel ON switch as a master power
switch. The DVD player will not respond to the remote unless this
master switch is ON (depressed).
2. If pressing the PLAY or TRAY button does not power the unit back up,
check for B+ by looking for Xtal activity (X101 = 2.4Vp-p, 1.6Vdc) at
IC102. Xtal activity means there is B+ but does not mean the entire
IC102 is OK. Replace IC102.
