A protection circuit was activated:
1. The V+10, V+5 or V+3R3 was short-circuited (See the protection circuit on "3.5 DVD MAIN ASSY (3/5)"),
or the value at V+10, V+5, or V+3R3 exceeded the standard value because of an abnormality in its power section.
2. The XPROTECT line up to the system-control computer (PDC133A) was short-circuited by grounding or was broken.
7. Accumulated power-on time display
• Hold the STOP key on the unit pressed for 8 seconds during Service Test mode. After the version for the system-control
computer is displayed, the accumulated power-on time is displayed.

Accumulated power-on time

• Power-on time is always counted while the power is on, regardless of unit's functions and operations.
However, it is not counted during Standby mode.
• The maximum countable power-on time is 255H59M (255 hours 59 minutes.) The indication will not advance beyond that.
• The accumulated power-on time basically cannot be cleared.
Abnormality in the DVD section
1. The V+6R8, V+5V, or V+3 was short-circuited, or the value at V+6R8, V+5V, or V+3 exceeded the standard value
because of an abnormality in its power section.
2. The VDET line up to the system-control computer (PDC133A) was short-circuited by grounding or was broken.
(See VDET circuit on "3.5 DVD MAIN ASSY (3/5)")
• If "OC ERR 1, 2" is not displayed when the unit is turned on in Normal mode, short-circuiting of the speaker terminals
can be suspected. (It causes speaker cable "+", "-" short.)
• If "OC ERR 1, 2" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected:
1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the
DAMP Assy is in failure.
2. The line between one of the above digital amplifier ICs and the speaker terminals is short-circuited.
3. The XSD line from one of the above digital amplifier ICs to the system-control computer (PDC133A) i sshort-circuited
by grounding or is broken.

• If "OVERTEMP" is not displayed when the unit is turned on in Normal mode, the unit is normal. The protection circuit
was activated because the temperature at the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA)
had become too high. Because it is likely that this was a temporary temperature rise, lower the volume of the speakers.
• If "OVERTEMP" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected:
1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the
DAMP Assy is in failure.
2. The OTW line from one of the above digital amplifier ICs to the system-control computer (PDC133A) is short-circuited
by grounding or is broken.
1. Breakage or short-circuiting of the communication line between the
µ
-COM (IC5501) and the EEPROM (IC5502) can
be suspected.
2. A failure in the EEPROM (IC5502) can be suspected.
