CD TEST MODE
Caution when servicing
(1) How to use extension jig.
1-1 How to Activate CD Test Mode
1) Connect 62 pin (test) of IC701 (LC72358N-9910) on
MAIN C.B to the 31 pin (VDD) by cable.
Correct between MAIN C.B. and CD mechanisms by extension jigs when checking CD mechanism
(TN-CCD1001-113J) operation.
(Refer to the following figure.)
2) Connect wire of ACC (red) and BACKUP (yellow) of power supply/speaker connector to DC+12V,
then connect Ground (black) to -.
When CD test mode is started, all displays will be lighted as shown in the following figure.
1-2 How to cancel CD Test Mode
1) Disconnect the cable of 62 pin (test) and 31 pin (VDD) of the MAIN C.B
IC701 (LC72358N-9910) and switch on the power.

•
Insert the “Test Disc” when operating all modes except search mode.
* NOTE 1
: There are CD operations are disable owing to the protection circuit being operated when heat builds up in the driver IC
if the focus search is operated continually for more than 10 minutes. In cases, the power supply should be switched off
for 10 minutes until heat has been reduced and then re-started.
