    Wells 7401 P763 25"7400 loses sync after 2-3minutes running.

    You might check my 7400/7500/2000/5000 repair log thread to see if I fixed a similar issue. It sounds familiar. https://forums.arcade-museum.com/threads/some-k7400-k7500-u2000-u5000-repair-logs.193468/

    Anyone got a Makvision M2929D7 lying around they can look at for me?

    Had someone give me a BBH Safari with a dead monitor. Fixed the blown caps and looked it over. Only other thing I've found is a crispy NTC (thermistor). Need a reference for a replacement. If nothing else I could try one off a D9200. If you have a parts chassis and want to send me one, I'd...

    Cap list listing (juniorsrevenge.com is no more)

    Sorry yall. The web host crashed my page and lost all of the docs I had posted, and the computer with all the files lost the hard drive. I have paper copies somewhere, plus I saw multiple sites that just copied my pages (including the 'compiled by modessitt' tag at the bottom) so I figured they...

    Wells U2000 - Did a cap kit, now screen is black and clicking sound

    It IS possible to fix color issues with a cap kit because the color signals go through some 10uf25v caps on the neckboard and if they are going bad you'll get color problems. It's also possible the contrast and brightness circuits can be affected. And if the 12v circuit gets affected it can...

    Wells U2000 - Did a cap kit, now screen is black and clicking sound

    1) I was sure about the first and World, but wasnt sure about Exotica. 2) if you knew that, you should have caught the error. (J/K) There are some differences between the 2000 and 5000 as far as troubleshooting. I have a big repair log on these somewhere here that might have something relevant.

    19K7203 wont fully focus..advice needed.

    A couple other things to check: 1) check that the focus wire to the neckboard is in completely and secured. If it isn't it can cause focus issues. 2) Take off the neckboard and check the focus pin on the neck. I've seen a bent, dirty, or broken-but-barely-hanging-on pin cause this. Check...

    Wells U2000 - Did a cap kit, now screen is black and clicking sound

    Are you sure that it's not a U5000? Most Cruisn's are medium-res.

    You may need an RGB to NTSC converter for a TV, depending on the TV.

    K7000 four leg c36/c39 vs two caps

    Most of the ones that were 4-leg only had the large rectangle screenprint for C36 only and the ones that had 2 caps had two separate rectangle screenprints for both C36 and C39.

    Wells Gardner U5000 Flowchart

    It has a 7400/7500 flowchart, and a U2000 flowchart which can be used for a lot of basic things on a U5000.

    U5000 - Anyone have any bright ideas?

    I know. I know. I took a break from it, but I'm going to try swapping the neckboard next.

    U5000 - Anyone have any bright ideas?

    Ok, I got raster now. After getting some sleep, I poked around and found that the +12v at pin 10 of U701 was only +8.9v. Traced it back to find Q703 was giving some funky measurements. I replaced it and my HV came on and I could turn the screen control up and down to get raster lines. So - I...

    WG6100 burned up an LV6100

    I just replaced a blown LV2000 Lite on a 6100. All the diodes and one transistor were shorted. Not sure if it was the cause or the result, but I found Q703 shorted, and three resistors near it burned up. Replaced those bad parts and put in another LV2000 and it worked fine.

    K7000 - smoking flyback?

    So I rebuilt a dead K7000 with new flyback and full caps. Replaced shorted HOT and VR and blown fuse. Checked C36 (fine) and width cap. Fixed cold solder. Powered up and get HV, but after about 30-60 seconds you hear a little crackling and smoke starts pouring out from under the flyback. The...

    U5000 - Anyone have any bright ideas?

    Got a U5000 chassis that I've installed a full cap kit, fixed cold solder, etc. No picture. B+ is a steady 119v. No HV. No neck glow. I've gone over the entire start up circuit and can't find a problem. Tried different remotes, different neckboards - it's not working. HOT is good. I'm going...

    WG K5600 issue with a helpful video! ;)

    Still can't see this video. Edit: Okay, now I can see it. When's the last time it was capped?

    Can you please help me identify these WG chassis?

    You'd think so, but there are times when a good working neckboard from one version gives you problems with another version. Not to mention the U5000 neckboard has parts the others don't.
