Korg Triton-Rack LCD Display has lines up/down it

Yes, SynthNut, ya gotta post the pictures when you get your Korg Triton Rack fixed. I wanna see that unit without all of those vertical lines, in its full glory!

On my new replacement display, the numbers on that small capacitor are slightly different. My new guess is that the small capacitor spec is “1uF 50V.” And then the number 2 beneath might have something to do with that batch of manufactured capacitors. I really don’t know for sure.

The number 2 beneath could potentially indicate a batch or manufacturing code, but without more context, it’s difficult to say for sure.

Not sure, have you had any luck since your posts? Sorry I have been gone for a while. I was more familiar with the old through hole parts vs smds. Are they electrolytics? Reminds me of the pg-380 Casio guitar issue. The electrolytic smd’s Dried out causing the strings to stop tracking on the synth side. The guitar as a guitar still worked. Is it possible to replace the electrolytics with tantalum capacitors to fix this permanently? My background was more of a builder of kits or from scratch like the Craig Anderton books. Etched board w FCL with etchresist pens etc from scratch vs troubleshooting and fixing. I did buy a complete panel from someone, but haven’t had a chance to replace it or use it. I have the tendency to start to many things and struggle to finish them. Please let me know your current status / progress. Thanks, Andrew

It sounds like you’re referring to a specific issue with a piece of equipment that involves electrolytic capacitors, possibly causing tracking issues on the synth side of a Casio guitar. The idea of replacing electrolytic capacitors with tantalum capacitors as a potential fix is an interesting one, but it would depend on the specific circuit and requirements of the equipment.
