Hello.
I bought Sony Walkman to restore, WM-FX822. I still waiting on rubber band, but radio works. Now problem is, I can see LCD screen in good contrast only looking at it at 45 degrees down from vertical, and still good all the way down to 90 deg (when its on the table and I'm on the battery side). When i move up to vertical view (0 deg) it fades to nothing.
I tried feeding it from lab PSU at 1.5V, nothing changed.
I attached service manual, IC702 is LCD driver chip. Whats can be done here, please?
Thanks!
