Need advice about a second-hand trinity

[Soumneal]

Hi; I'm just new in this forum and playing live with a band. I'm about to purchase a second hand Korg Trinity from the owner (I don't know the exact model since I haven't examined the instr. yet). I need to be as sure as possible about the machine's not harmed or will not create any mechanical or electronical problem. How should I check the board working as properly as a new one? What functions and parts should I examine? Is it necessary to take a look at the internal parts?
I'd be glad if anybody shares his/her experiences.

there should be some kind of hardware test included which examines every single thing...run it and thou shall see... :wink:

Found the user's manual(s) online but still searching for that option. Do you remember under what keyword could I find it (nothing under "hardware test")?

Might be worth looking for "diagnostics" or something similar (that's what it's called on the E-MU)... I'm not familiar with Korgs, sorry!

Hello there,
On the hardware part I can advice some things to check as they are the first to get damaged...

1- The two bottons next to the slider bar these can be broken very easily if used a lot

2- insert a headphone and check the output... some of the boards have a problem with this you can only hear on one side.

3- Check all 4 outputs if they're working... the soldering is realy crapy on the outlets

4- the joy stick can have a really bad spring and too many people had this problem after a long use (since you don't know for how long it has been in used) just try check if it's unstable X Y axis

5- Ribbon can be scratched try to see if a tape has been placed over it

6- check the Volume potentiometer if it screaches ... these are humidity anemies.

7- Software tes Taken fro Eddy Degan during the forum days :
(I've tried it and really it is good to go thru your K/B)
"There are, yes. However, be advised that they are 'hidden' for a reason, that reason being that they will erase data from memory, and possibly hard drive (I don't know for sure), so only use if you have nothing to lose. The SY85 for example had the ability to test the floppy drive, but it would destroy any data you had on the disk in the drive at the time. Consider the implications of doing self-diagnostic tests on a SCSI drive used for 4-track recording. Having said the above, the self test routines can be accessed by switching the Trinity on while holding down the <ENTER> and <5> keys. From then on you're on your own. It's a good way of generating test tones, testing noise levels, joystick calibration and a whole host of other stuff. Very useful for diagnosing a faulty controller! Use of the self-test routines will erase your joystick and touch screen calibration settings so be sure to reset these after you exit, by going into Global mode. "
