    Medalist Dart Star - CRT removal

    @jimbodeanny Dumb question...what is the best way to remove the neckboard? Take off the monitor bracket first I'm guessing?

    Medalist Dart Star - CRT removal

    What is the best way to remove the CRT and chassis from a Medalist Dart Start machine? Should I remove the top section that is bolted to the base, then remove the CRT assembly?

    Price check - Tempest upright

    I appreciate the feedback from everybody. Got it down to $1,000 and the seller is throwing in a dart Star dart machine. So picking it up seems a no brainer at this point. I previously picked up a non-working asteroids and fixed it up. I’m working my way through a dead space duel with Andrew B’s...

    Price check - Tempest upright

    All original boards. Can't speak to whether the monitor has been maintained, but it is currently working. Thank you!

    Price check - Tempest upright

    Thinking about picking up a Tempest upright and wondering the value these days. The cabinet art is in nice shape, same with CPO. A few nicks, bruises and dings in the cabinet but no major damage. The vector monitor is working and it boots and plays. Seller wants $1,200. Also wondering about...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Final update - replaced both T2 and T3 on the neckboard, which fixed the red tint issue. Still adjusting all the color pots, and making some adjustments on the remote board. Image looks pretty good now, and all the issues I’m aware of have been repaired. Appreciate all the wisdom on KLOV and...

    Price check on Joust, Space Invaders and Asteroids

    I ended up giving the lady the $1,000 she was asking for. I have a soft spot for old ladies. She let me go through her late husband's collectibles, so I snagged some old Star Wars stuff for my 5 year old.

    Price check on Joust, Space Invaders and Asteroids

    The Joust cleaned up nicely. Sent the 3 game boards to my board guy to service. Meanwhile, I recapped the sound board, recapped and reflowed the monitor chassis, recapped and rebuilt the linear power supply with new components, headers, etc. from Arcade Parts and Repair. These early Williams are...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    For posterity, I thought I'd update that I swapped T6 on the neckboard , I had previously changed T7. I think changing T6 fixed the excess blue issue I was having, now things are too red and I think I need to adjust the neckboard pots again. Also the screen is doing this subtle weird pulsing of...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Got the 260 ohm resistor and installed it. R36 was the culprit. Thanks to everybody that assisted me in this thread. I’m marking this as solved, however the perfectionist in me thinks I need to do a bit more work to get the image looking crisper. But it looks pretty good now. And I learned a lot...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    The latest development is I’m going through the neckboard components one by one, and R36 (270 ohm resistor) is open. Not sure if this could cause some of the image issues (my internet research of other forums/posts says maybe).

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Finally got around to restoring the trace and swapping the negative legs of C2 and C3. The blue horizontal lines are still there. One weird thing is that the lines seem to change color depending on how adjust the cutoff pots. They will change to whatever color the pot is maxed out on (see...

    It is crystal clear now. Thanks MKL!

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Thanks MKL. I really appreciate the assistance. It could be because I've been working 14 hour days with not a lot of sleep, but I'm having a little trouble understanding. Lift the negative legs of C2 and C3 and swap which connections? I will properly restore the broken trace and remove the...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Ok, I replaced LM1203 in a socket but the horizontal line issue is still there. I will try swapping the blue and green wires to the neckboard, but I’m not exactly sure which ones to switch.

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Thanks MKL. It seems there are a lot of issues with this particular chassis, so I'm working my way through. I'll try replacing and socketing LM1203 on the neckboard, I already ordered that part just in case. I'm guessing the ceramic caps that are soldered to the pins of IC1 are original and need...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    I made another discovery earlier today while poking around - R236 is way out of spec. I think it’s supposed to be a 1 ohm flameproof and it’s testing open. I have a new resistor on order. Could this be the cause of the horizontal raster-type lines happening? This resistor is right next to the...

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Other observations - neither the blue cutoff or the blue adjustment pots seems to make much of a change when I mess with them. The green cutoff and red pots definitely cause more of an effect on the image.

    Hantarex Polo 25" - vertical deflection issues *SOLVED*

    Here’s where I’m at: I swapped out RV5 for another 1k pot from the neckboard. There was no visible change in the horizontal lines after adjusting the changed pot (first picture). Then I desoldered one leg of R34 and blue is completely gone (second picture). I’m thinking maybe I should just...
