Panasonic Q - DVD no picture / Service codes / Swap components

Post by LSL84 » Thu Jul 22, 2021 12:02 am

Hello everyone!
  1. DVD no Picture
    Days ago I wrote this thread viewtopic.php?t=3579 I tested my Q with another 2 new RAF3011A laser lens and it still didn't read GC discs games, so I had a wrong decision, I took an image of a Panasonic disc, burned it and played it on the Q, after this action the DVD player the DVD player hasn't picture but sound is ok.

    Almost 5 years later I took some time and analyzed my Q, I found the problem with the GameCube mode, it was the 32-pin FFC between GC board and laser controller board.

    So now I would like to fix the DVD player. I found this thread viewtopic.php?f=16&t=3741&p=38431&hilit ... nic#p38431 but the last reply was Tue Mar 28, 2017 8:16 am.
  2. Service Codes
    When I started to analyze the Q hardware, I compared it to some Panasonic DVD service manuals and tried to run some service codes. I found out how to make some codes work. I would like to compare some codes of my Q with another one, could someone help me? All codes below are cancelled automatically 5 seconds later and it may execute on DVD mode without disc.
    • Display Region - Press "6" on the remote control + STOP on the Panasonic Q. It will display in the format: X YY ZZZ where X is the Region, YY is the system color(probably NN → NoPal/NTSC) and ZZZ is the Panel controller jumper information. My Q displayed: 2 NN 151
    • Firmware version??? - Press "7" on the remote control + STOP on the Panasonic Q. It will display 6 characters. My Q displayed: 60A062.
    • Some System information - Press "7" on the remote control + STOP on the Panasonic Q. It will display 5 information (FEP, SRI, 0DC, AV_, SYS). My Q displayed: FEP 000300, SRI 000200, 0DC 000304, AV_ 000096, SYS 450071. I guess that SYS is the firmware version because when I tested on DVD-RV41 the SYS is the same result when I execute the version display code and the another information (FEP, SRI, 0DC, AV_) are the same on Q and on RV41.
  3. Swap components
    I bought a Panasonic DVD-VR41 because it has an identical controller board. I had the idea of ​​replacing some components, such as IC Flash and EEPROM. What do you think? Or try to adapt the entire board and swap it?

Did you ever get anywhere with this? Same boat as you, no video when using DVD mode, drive doesn't even attempt to spin discs. Suspecting a bad FCC cable and plan to order replacements but open to input.
