Hi Bob and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, are you able to locate the display module / front panel PCB (printed circuit board)?
Can you please post a clear closeup picture of this display module?
Sorry but I have to ask; are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
Great on the DIY Bob!
Yes, the front panel / where the display module is soldered too would have 2 of the test points.
Do you have a download link of the service manual? Having a common reference would facilitate suspect referencing.
I understand and yes please; post back with a link to the service manual when able.
Thanks for the picture Bob but for some reason, the "...Service manual for the stereo...." failed to show up.
Can you please try uploading to https://www.dropbox.com/ and post back with the download link?
Got it; TNX again.
On p.46 top left, have you checked R001 and LP001 & 002 (most likely)? ...presence of +12V on R001 (least likely)?
A friendly reminder; voltage measurements by its very nature requires that the Pioneer be plugged in, turned ON and therefore LIVE! Please exercise due care and caution.
From the picture posted, it would appear to be the parts with slightly larger solder blobs behind the display module between the 2 screws.
Please post back results / observations of the above once tested.
Copy that Bob and would look forward to an update tomorrow or when able.

Appreciate the update Bob.
Glad that the above information served your purpose and would appreciate a Positive Rating and/or an Accept (if haven't done so).
Good luck and thank you too for the opportunity to be able to share the information.
