The Coin Battery Situation on the Siel DK80 Is A Bit Unusual

In my previous video you saw me tear down a Siel DK80. Today I am going to replace the lithium coin battery. Be sure to backup your patches to the cartridge before proceeding.

Repairing a Siel DK 80 Synthesizer Weird Power Issue

Today I've got a Siel DK80 with an issue. Both 7-segment displays are very dim, and also the front panel LEDs are faint. Seems like a power supply problem. What I noticed is when I depress the power button fully to turn it off, the display and leds come back to full brightness. Seems that the power switch might be going out. Let's teardown the synth and replace the switch to see if it fixes the issue.
