Hi,

Subject: [PolySix] Battery leak problem.
Hi,
I have tried to fix my Polysix that had a battery leak.
Before i started to repar the problem was that no button was working (for memory and tape) and allmost all the LEDs was turned on.
After I removed the battery and IC30 and IC31 I cleaned the board and started to repair the traces with new wires. And then I started to messaure the traces and everything seems to be looking fing.
I then installed the card in the Polysix again and turned it on. All buttons works fine and the only LEDs that are turned on are 7 and 8 if the Tape switch is in Tape Disable. If I change Tape Disable to Enable only LED 8 is always on.
I can save sounds, but only 4.
memory 1 and 5 save same sound
memory 2 and 6 save same sound
memory 3 and 7 save same sound
memory 4 and 8 save same sound
Does anyone know and can help me with what trace should I look at to get rid of this problem?
I have followed oldcorwn.nets guide alot in this case.
Here's two photos of the LEDs
