Members wheresgrant3 Posted November 16, 2004 Members Share Posted November 16, 2004 I hate damaged gear period! I have a Korg DW8000 that I bought last summer used for $250. It appeared to be in pretty good shape when I received it. I used it for a total of maybe 8 hours over a month, an then ... poof... it stopped powering up. I opened it up last night and I'm guessing it is either a bad supply or power transformer. So I'm wondering what to do with this thing. I definately want to get rid of this unit... but to sell it, I have to get it working. To get it working I'm going to have to dump some money. The closest reliable shop is Rogue Music in NYC... 1 hr 1/2 away. What do you guys do with vintage gear that needs to be repair... do you get it fixed, or does it sit in your closet collecting dust.

Members arpeggio Posted November 16, 2004 Members Share Posted November 16, 2004 I see a lot of it on E-bay Sometimes people can use them for parts or project pieces and will buy them for that. Just be up front in the description that it's got problems and you shouldn't have any flak from the buyers. Cheers. Link to comment Share on other sites More sharing options...

Members TheProteus Posted November 16, 2004 Members Share Posted November 16, 2004 What's wrong with it? Describe the symptoms and I can tell ya whether or not it would be worth repairing. "just stopped working" doesn't cut it - did the power just die, or is it behaving intermittently? Link to comment Share on other sites More sharing options...
Members sizzlemeister Posted November 16, 2004 Members Share Posted November 16, 2004 Yeah, there are those of us who go for dead or broken units because they come cheaply. You could probably put it up on Ebay and get $20 for it or give it away to someone who wants it. Put me on that list! I'm in the same state;) Link to comment Share on other sites More sharing options...
Members mytee2.0 Posted November 16, 2004 Members Share Posted November 16, 2004 I feel your pain I bought an EX8000 from a user here with an ultra high post count for about $100 iirc, may have been 150. It didnt come with a power cord so I had to order one on special order from sweetwater which took a month. The seller knew that it would take this long for the cable to arrive and when it did, it of course did not work at all. I asked the seller for my money back at which point he disapeared from the forums I sent it to roguemusic for an estimate which was $200. I said no so they asked for $20 to ship it back which was reasonable, but I have yet to respond, this was about 4 months ago. I just now remembered....

Members Kirumamoru Posted November 16, 2004 Members Share Posted November 16, 2004 Actually, my "mail it to me" was in response to Jazz+'s post. If he's just going to junk it, I'd take it. Kiru Link to comment Share on other sites More sharing options...

Nope... just never power up again. It worked fine. I put it in it's case. A few weeks later I pulled it out for some fun.... no power. On/off, on off, on/off... no power at all. I replaced the power cord... still no power... nada, nothing. It just stopped working. Link to comment Share on other sites More sharing options...
Members sizzlemeister Posted November 17, 2004 Members Share Posted November 17, 2004 Get yourself a voltage meter and start from the the power cord connector inward and check for continuity. Find something that you can print out that will help decipher what each component should read (based on the component's markings). When you find the a component or trace that isn't reading correctly then you've most likely found your problem. Replace it and your DW8000 should be good to go.

Members Keith korg Posted November 17, 2004 Members Share Posted November 17, 2004 Originally posted by Jazz+ The power board to my D550 backlight is not putting out enough volts, so the light is off. I think I will throw the whole unit away... Are you sure it's not putting out enough volts ie have you measured it or could it be that the backlight LED's have gone? Get yourself a voltage meter and start from the the power cord connector inward and check for continuity.

When you find the a component or trace that isn't reading correctly then you've most likely found your problem. Replace it and your DW8000 should be good to go. Unless you no what you're doing it's not advisable to have a unit live while you're poking around, switch mode power supplies generate high DC volts (worst kind for shocks). I must say it does sound like it could be a connection issue because of the way it failed (almost instant). But then because you haven't had it powered up for a while it's hard to say if the unit was showing signs of impending failure like flickering screen/power indication. In cases like this it's almost certainly the supply. If you look at the board to the left of the transformer the black upright components to the middle of the board capacitors/condensors are what usually go first. Check to see if they have "domed" what I mean here is that the top of the surface is usually flat but with age what tends to happen is that the top domes outward and upward because of internal pressures. Second when these babies leak it smells a bit like bad fish. Leaking capacitors aren't happy capacitor. Not only will they operate in a sporadic manner dielectric fluid will leak onto the board and corrode through circuit tracks. Heatsink components like darlington transitors/field effect transistors "usually" go quite spectacularly and blow the surface off of the body have a good look at these. I'm in a similar situation I have an sy77 that I'm thinking of selling but the floppy drive is dead and the backlight is dead and because of this I can't get top dollar. I know there is a company that sells correctly sourced drives and also a backlight company here in the uk. I've managed to source a 750k drive for Link to comment Share on other sites More sharing options...

Members davehorne Posted November 17, 2004 Members Share Posted November 17, 2004 Why not take it to a local guy who fixes TVs. If he can get his hands on a schematic it should be quite easy for him to repair it. Even without a schematic he might be able to narrow down the problem. What is is going to cost to have someone just take a look. Link to comment Share on other sites More sharing options...
Members wheresgrant3 Posted November 17, 2004 Author Members Share Posted November 17, 2004 Well put it this way... DW8000's are going between $200-$300 on EvilBay. So if it's any more than $150 to fix then it's too much. I really don't want or need this board. I might try to fix it myself I guess... make it a project board. We'll see, though.

Members downwithgender Posted November 17, 2004 Members Share Posted November 17, 2004 just sell it as is with no power cord, say you have no way of testing it, and let someone else deal with it. Link to comment Share on other sites More sharing options...
Members cybermooks Posted November 17, 2004 Members Share Posted November 17, 2004 That really sucks, to cheat someone else. No wonder no one trusts musicians. DWs are very cheap so not worth repair cost; you can get another and use that for parts. Rogue is pretty expensive though. Try East Village Music; they are very reasonable on repairs. As far as backlights go you can get them from Telesis in Ca. very inexpensively. Hardly worth trashing a synth for. Link to comment Share on other sites More sharing options...

You know, I hardly think that putting a keyboard on ebay with no reserve and a description that reads "This doesn't work. I think it's just the power supply, but I don't know, so best offer takes it, sold AS IS" is cheating anyone. Kiru Link to comment Share on other sites More sharing options...

Kiru I thought he was reffering to this quote: just sell it as is with no power cord, say you have no way of testing it, and let someone else deal with it. Which if I read right is basically saying try and dupe someone into buying it, is a pretty shabby way of dealing with people Link to comment Share on other sites More sharing options...

Members MuzikB Posted November 17, 2004 Members Share Posted November 17, 2004 If you have the know how and want to keep it, just repair it yourself. Purchase another DW and fix it. If the DW you later purchased is in better shape, then keep the old one that's not working for parts. I'm doing that now with a pair of Akai AX60's. Some know how and a Digital Multimeter can go a long way with older synths. Link to comment Share on other sites More sharing options...
