Hi, when I turn on my Korg DTR-1000, only the Mute Light, Center tuning light (thats just below the Korg Logo) and the Flat Light only come on. Don't know what the problem seems to be, but I've changed the fuse, and tried different power cables with it. Any info would help. Thanks -John

Sometimes tuners can be overly sensitive! You've just got to sit in a quiet room and wait for the needle to settle, then give it another try.

hello sir,

It may help you.

NOT a fuse... thaat person knows nothing. There is something wrong for sure. Check if one of the buttons or keys MIGHT be stuck down (depressed). Sometimes the units check that all the control buttons are up and they don't really tell you why they fail to start. Beyond this a repair shop is in order.

Have you tried the capacitor replacement trick here: http://www.fixya.com/TipsAndTricks/ThreadView.aspx?thid=741402 ? Use the method described (two places - look at both) to open the back of your TV. Look on the upper board (the power supply - where the 110 vac goes) for damaged capacitors as witnessed by their bulging tops. If they look ok and nothing else on the board is obviously damaged, I would go ahead and replace the three capacitors there. Two located near the center top of the board are 1000 micro farad 10 vdc electrolytic and the other right below the first two near the center of the board (a bit larger) is 1000 micro farad 35 vdc. Replace them all with 1000 micro farad 35 vdc (or wvdc) electrolytic caps - you can buy them from Radio Shack for $1.50 or so each. This assumes that your FLM-3732 is similar to the FLM-373B that I have. Good Luck!

well i hope you've figured it out by now, it's a really cool looking tuner and i love it. but if you are still having problems...
the switch on the left side: OFF, ON, LMP (ON with a little light so you can see in the dark)
The number and letters you see across the top of the interface indicate which string it is tuning to. 6E is the low E string (the thickest one) and 1E is the high E string (the thin one on the bottom of the guitar), i've seen many people get confused when they've tuned those two.
You can leave the tuner in auto and it will pick up what string you are trying to tune. but if you are having problems getting the correct string or whatever the case is, you can switch to manual mode. click the only button on the tuner and the specific string will light up on the interface.
If you press and hold the button, the tuner will go into flat mode, tuning all the strings flat.
once you have the right string and you're tuning it in, you want the needle to be centered.
that's pretty much it. enjoy!

search diagram microkorg in google, and sorprise is the manual service n pars of ic 5 is IC S-8520F33MC-BNS-T2 best regards!!!!....

The CM-100L Contact Microphone is a perfect compliment to any tuner that offers an audio input jack. The mic can be positioned to get a more sensitive reading, while allowing the tuner to be positioned for easier reading.
The jack is a 1/4" male phone connector.

that is on the official site...
