    Got my ART SGX2000 fixed

    ART no longer supports these AT ALL. They not even carry any parts for them any more.

    So anyway, I found a guy in West Virginia who works on these things. I got my unit back today and it fucking rocks!!!

    The backlight on the LCD screen was burned out.

    For 100 bucks plus shipping, he replaced the LCD. The green background is now brighter than the original.

    He upgraded the software from v1.05 to v1.10 (the most recent....1994 haha), and he put a brand new Sovtek 12AX7 tube in it.

    I am impressed.

    Here are a couple of fotos:

    If anyone here needs work done on stuff like this, just PM me and I will let you have his email addy.

    His prices are reasonable, it was really fast turnaround, and my experience with him was cool.

    And on the subjet of ART gear, I just snagged an ART NightBass for 100 bucks on eBay.

    Woot!

    They are still in business.

    I dig my SGX. And am looking forward to checking out the Nightbass unit once I get it.

    Nah....living in the US I almost never hear of them anyway. Though I did wear an umpire's shirt back in the day when performing on stage...

    I decided on using that as my personal motif back in 1979.

    Long before Stryper ever came out...and before Quiet Riot got big.

    Just thought it looked cool.

    These are my number 1 (Flying V) and number 2 (JB Player neck-thru-body Strat) sons...

    cool bump i'm the proud owner of a '91 digitech gsp 21 pro. it's been upgraded twice, had a new led in the footswitch and a new memory battery. i bought it new, sold it to a mate, and bought it back again. the fucking thing refuses to die or go away, it's part of the family, and at the time of this writing still sounds fantastic.

    Can I get the repair tech's info too?

    I have an SGX 2000 Express that's having the flickering LCD backlight issue. Looking to see if it can be fixed. I'd appreciate any contact info for the guy that fixed yours way back,

    Wow.

    I have to laugh. About once a year someone is googling this subject, and they wind up here.

    It was a guy in West Virginia who fixed mine.

    I have not spoken to him since he fixed mine, so I am not even sure he still lives there.

    I have sent you a PM with his old address, and a possible phone number.

    Let me know if he is still repairing these, so I can inform other people who come searching.

    Hello, I am new to this site. I just bought a SGX2000 Express all updated for $90 works great. Anyway I was just wondering if you could send me the info on the guy that did your LCD repair. I am an electronics engineer
    and plan on doing the repair myself. I just wanted to ask him what type LED lights it takes. If I don't rach him I will just pull the board and look and either order them or see what I have in stock. Thanks

    Could somebody please send me the contact info on the West Virginia repair guy or any other person who might be able to replace the LCD display module? Ampman, could you send me your info? BTW, I think it's a pretty special display because looking around the net, I can't find a 16x2 display that's 80mmx27mm. So I don't think you're going to easily find a replacement. If you do, please post it here. Thanks!

    Thanks to Hardrock69.
    I was unable to get my SGX2000 display backlight fixed so I did some research and with a little wire splicing, I got a new display module to work. It's really easy. Here's how
    Go to
    http://www.ebay.com/itm/351080036231
    The source is bgood2010

    This is not a sticky ebay item. You may have to search for a 1602A in the electronics. I recommend bgood2010's store. I found many, some less expensive but were shipped from China. I've shipped internationally before, and it has failed for me because the item gets lost in customs. So this 1602A is shipped from California. It arrived in 2 days.
    You'll notice it comes without a header, so you need to go to your local electronics store and buy a 16 or longer 0.1" space header. You can use your side cutters to cut it to the length you need (16 pins)
    This 1602A part pinout is slightly different from the display used on the SGX2000, and the backlight needs 5V from the 5V supply rail. The SGX2000 backlight does not come from the 5V supply rail, and without a schematic I have no idea where it comes from. So to be safe, you need to put ground on pin 16 and 5V on pin 15 of the display connector.
    First you have to cut the wire from pin 2 (5v) and the wire from pin 15 of the display connector. Splice the wire coming from the display connector pin 15 to the 2 wires coming from pin 2. This connection now has 3 wires and supplies the 5V to the display backlight as well as pin 2 of the display. Tape or use heat shrink tubing to make sure it's insulated.
    Then cut the wire from pin 16 of the display. Splice the display side wire to the motherboard side wire coming from pin 15. This will connect ground to the display backlight. Again, use tape or heat shrink to insulate this connection.
    You have one open wire coming from the motherboard side pin 15. You can insulate that one to be safe, but is probably unnecessary.
    Mount the new display, plug it in, and Lo! youíre backlit again.

    Now I'd like to find a source for the 27256 v1.10 eprom. If anybody knows of one, please post it here for us. Thanks!
    Jimbo

    I can't believe there isn't an A.R.T. forum. I know they sold pretty well back in the day, there has to be some kind of user base.

    ART sent me a PDF schematic. How bout that customer service? Wow! So looking at the schematic, I see why these things are so expensive. Anyway, it turns out that the display has its very own 5V regulator. So to use the 1602A LCD display, all you have to do is to swap pins 15 and 16. So simply cut pins 15 and 16 from the motherboard connector and connect pin 15 of the motherboard to pin 16 of the display, and pin 16 of the motherboard to pin 15 of the display. I did this and it works fine. If you did the mod I suggested above, I would recommend changing to this mod because the 5V rail I used in the above post supplies all the logic, including the z80 processor. I don't know how much headroom that 5V regulator has, so I used the separate regulator (this post's mod) and it is working just fine.
