Try pressing record multiple times and see if that changes anything. If not, try this: https://boomboxery.com/forum/threads/record-switch-bar-example.28289/

Use a headphone and see you get both channels.
The power amplifier section is the next to check. One channel was dead due to a faulty power amp on my GF777.
