    K4900 Refresh And Rejuv

    Fixing several monitors for a fellow enthusiast in KC. When testing this, it powered up but I had an all red screen with retrace lines. I suspected a shorted ren gun in the tube but I soon discovered the neck board was cracked. Exposed the traces, flowed some solder bridges to restore the...

    19” K8000 Medium Res…Or Not?

    @LittleLarrySellr sent me a K8000 to check out for him because he wants to use it in his Super Sprint. He could not get it to sync with his setup. He thought it might have had a fault, so he asked if I could take a look. I had never seen, worked on, or even heard of a K8000, so I said "sure."...

    G07 CBO - Very Dim Game Image - Open R516 and R517

    The G07 in the Rally X at The Arcade was getting dimmer and dimmer by the day. Took it out today and brought it home to the test bench. It had been capped (way back in 1992) and it looked to be in decent shape, other than being filthy. Cleaned it up, capped it, reflowed it, and hooked it up to...

    25" K7000 Vertical Oscillation/Foldover And Super Hot IC3 Repair

    25" K7000. Severe vertical oscillation (only at the bottom of the screen) and the image starts folding over, losing sync, and going crazy after a minute or so (the IC3 heat sink gets scalding hot at this point). The story with this is the chassis had vertical deflection issues and the original...

    27" KT-2914 Repair - "Won't Come Up"

    This chassis was donated to me in a "won't come up" condition. A few caps had been replaced in an attempt to fix it but it appears that at some point, the chassis had been severely mishandled. First thing I did was attempt to duplicate the issue. It did power up and I had high voltage, but the...

    U2000 - Dead Horizontal Section Repair

    U2000 on the bench. No signs of life. No ticking, no sounds, nothing. Report was it was working and then died with a burning smell. Quick testing revealed the power supply was working but the horizontal section was not energizing. Nothing visually looked bad. No burned spots, burned components...

    G07 Corner Snapped Off From Insufficient Packaging

    G07 was sent in for repair. Opened the box to find this. A little super glue, a little fiberglass pen work, and a few solder bridges later...it's all fixed. F901 was blown due to a bad flyback. Replaced the flyback, replaced F901, all new caps, full reflow, full inspection to verify nothing else...

    Mortal Kombat 4 Tube Rejuv Failure - TV Tube Swap Success

    Just picked up this MK4 today. 32,000 credits played. All original. Works as it should except the monitor was all Red. Got it home, removed the monitor, and threw it on the bench for testing. Hooked up the B&K. Got everything setup and ran through the Emissions test. Sure enough, the Green and...

    G07-CBO Proper Flyback Replacement Procedure

    Got a G07 that needed a new flyback. While making a video on the repair, figured I'd show how to properly replace the flyback. A lot of people just install the replacements as they are, but the G2 wire needs trimmed and routed correctly. The procedure starts at the 19:47 mark...

    K7000 Decreasing V.Size Causes Black Blobs

    25" K7000 on the bench. Was a "parts" chassis that I revived. After getting it all fixed up, it's working and looking great but when testing the V.Size adjustment, I noticed that if I went all the way down with it, I get these black blobs. Suspected the flyback so I replaced it. Nope. The whole...

    25" K7000 Full Vertical Collapse - Abnormal Cause Fix

    Got a couple 7000s in for repair. One with full vertical collapse. Another with partial collapse. Started with the one in full collapse. Gave it a full look over and the first thing I noticed was a missing fuse. Checked all the normal power components and they were good. I also found numerous...

    WWF Wrestlemania PCB Not Booting With Bad U118 Repair

    Got this in for repair along with a U2000 chassis. Set the U2000 aside and started with this. Gave it an inspection and noticed it had no battery installed. SOME of these Wolf Unit boards require a battery to be installed/battery holder contacts to be touching in order to boot, but others do...

    If You Will It, It Is No Dream - Lebowski Acquisition!

    Went down to Tulsa yesterday and snagged this. Starry apron and Buthamburg playfield. This game is from the last shipment of TBLs and has the Buthamburg playfield instead of the Mirco. 1491 TBLs had a Mirco playfield and around 33 games have a Buthamburg. Been waiting for one of these to pop...

    WTB: Nintendo Super System Controller

    Need a spare controller if anyone has one. We had one meet an aggressive end at the hands of a child who was using the machine like a jungle gym.

    25" U2000 - No Colors No Contrast Repair

    Picked up a couple non-working U2000s from a fellow enthusiast a few days back. Got the first one tackled today. It already had a cap kit and a new flyback installed but there were a lot of destroyed pads and traces that I had to fix along with some smashed components. Got all that fixed up but...
