JBL Cinema Vision™ Diagnostics
Troubleshooting routine for field service personnel
The purpose of this document is to try and isolate any video problems that could be
attributed to either the:
1) CVPD50 (Plasma Display Panel)
2) CVR700 circuitry (exempting the Shielded Video Control Box)
3) The Shielded Video Control Box in the CVR700
Note: Do not confuse the Shielded Video Control Box in the CVR700 with the “Video
Board”, which is a different PCB in the unit. (See exploded view Pages 48-49).
It is important to check all items as outlined below before reaching final diagnosis.
For the following procedures, please refer to the drawing:
Test Set-up and connection diagram
Symptom
Possible Cause
Solution
Unit does not turn ON
Digital Link Cable between CVPD50 PDP &
CVR700 not (correctly) plugged in.
Check connections on both units
and if connections seem OK, try
another cable.
LED on CVPD50 PDP
is blinking (amber)
Main Power Switch on CVPD50 PDP is turned
OFF or AC cord is disconnected.
Check AC cord on both CVPD50
PDP and wall AC outlet, main
power switch on the CVPD50 PDP
Be sure that no defective cables or defective customer equipment is the reason for a
malfunction:
•
Check visually that all cables look OK.
•
Change the Digital Link cable between CVR700 and CVPD50 PDP with a known, tested one.
•
Change the AC power-cord for the CVPD50 PDP with a known, tested one
•
Change the video cables from the customer sources to the CVR700 with known, tested ones.
•
Check the system with a known, tested video source (Composite (CVBS), S-Video (YC),
Component (Y/Pb/Pr or YUV), DVI, VGA)
Possible malfunctions: CVPD50 PDP (Plasma Display Panel)
The following errors indicate a malfunction in the CVPD50 PDP (For testing, use the internal DVD
player of the CVR 700)
•
CVR700 turns on, LED on CVPD50 PDP turns green but Plasma doesn’t turn on (check for the
sound of a relay clicking inside the unit – no click sound means that SMPS did not turn on)
Æ
Defective Plasma SMPS)
•
Pixel failures more than allowed in the specification
Æ
Plasma-panel itself defective
•
Line-, column- or half-column-failures (e.g. permanently white or single-colored)
Æ
Plasma-panel
itself defect
If any of the failures listed above are confirmed, the CVPD50 PDP needs to be returned to JBL as it is
not field serviceable. Call 1-516-255-4525 for instructions.
Possible malfunctions: DVD/Receiver CVR700 (which includes Video signal processing for the
CVPD50 PDP)
NOTE: The CVR700 is comprised of a DVD/Receiver platform and a high quality Shielded Video
Control Box. This Video Board can be identified as the large shielded metal case that is mounted
inside the CVR700. It is very important to positively identify whether the problem resides in the Video
Board, or in the remainder of the CVR700 circuitry. The Video Board is not field-serviceable should be
returned to JBL if found to be defective. Call 1-516-255-4525 for instructions.
