Fostex XR 7 need help with bargraph meter

Hello everyone!

I’m seeking advice on how to repair my bar graph meter, which is currently unresponsive. I would greatly appreciate any assistance. I love this stuff and enjoy making things with it.

When I play a cassette, the bar graph meter remains stuck (see PIC_1). However, when I plug in my headphones, the bar graph get stuck to a higher position. When I remove the ribbon (as shown in PIC_2), the bar graph functions normally during cassette playback.

I hope someone can assist me with this issue. Thank you :)
