How to test and adjust the B+ voltage on a WG 6100 monitor - TEMPEST FIX PART #4

[@eichertiger4728]

I have a very cheap idea . Drop a little bit contact spray over the controler , then move it with the special screwdriver, you will have then a better contact in this controler and the tension is constant . So much thanks from Germany, it´s so interested . You are the BEST !!!!!!!!

[@zebart]

B+ power is high voltage DC that is applied to the Plates of the Vacuum tubes in the circuit. "B" was the name of a battery that I believe was 45 volts. At least two B batteries were used to obtain a B+ supply voltage of 90VDC for "Portable" usage.

[@racer4200]

I'd continue on the Tempest while all the work you've done is still fresh in your memory.

[@jamesrbrindle]

Had similar problem, check, clean and reset the connections to the screen and focus pots. Your HV is absolutely fine. B+ is fine and not wavering.

[@chrisgoater5616]

I am so jealous of the prices in the states. Up here in Canada, the cheapest working game I've found is $450, but starting price for a working game on Kijiji (Craig's list in Canada) is around $800. One close to me was selling and empty cabinet for $200. Love the videos and will start collecting soon!

[@Johnsarcade]

+Chris Goater dont make me come up there and find the deals. :) Keep looking!

[@amosso]

Hey John Finish that damn Tempest :D Thanks a lot for your videos, can't wait to see the next one !

[@Pixilshooter]

Try replacing the flyback first and did you replace the caps on the PCB in the cage? If that fails ... move on to HV section.

[@WastingMyPotential]

When My LV200 went out on my Star Wars it also took out the diodes that allowed me to adjust the B+ on the HV board... I will have to check but I think it was D901, 913, 902....

[@MichelCastonguay]

John don't listen to them, you mush have Tempest fixed, this is one of the best arcade game ever made and you can't let it go.

[@Darryl603]

Hi John, You can back probe a connector with a test lead to get your readings and the lead will usually stay in there. Do you have a spare pot you can throw in there just to rule it out, one way or the other? It seems flakey to me. The voltage didn't change and you could adjust it back, so maybe the pot's bad or dirty or corroded. You could turn the game off and spray it out with deoxit, work it full range several times, spray it again and dry it with air. Thanks for the video and keep us in the loop. See you in the next one, BYE!

[@ArcadeFreak-gw5rp]

hey john i think you should just rebuid the b+ box and the flyback you already have the parts and once you do that the monitor should last you years because at that point you would have basically rebuilt the whole chassis keep up the good work love the videos

[@kamiboy]

Well, John. The silver lining here is that at least that monitor is relatively simple and well documented. I got a X68000 monitor here imported from Japan with erratic fluctuating brightness. It has at least four times as many electronic components on its various boards and no documentation whatsoever.

[@shabazz18]

That's usually a bad flyback on raster monitors

[@kamiboy]

@@shabazz18 It was a cold solder joint.

[@DamianReloaded]

One thing I'm noting is that I can see the vertical refresh of the monitor happening if I play the video in 60fps and that usually doesn't happen. Could there be something wrong with whatever handles the refresh frequency? Do you have another neck board to try out?

[@shovelhedded]

Yeah, I'd swap he flyback for sure. It's controls are really wiggy! If the focus knob is messing with brightness and turning the whole screen black, why not swap it out if you have one? It obviously has some issues. If the B+ remains unstable after that then do the HV cage rebuild. But it might just be a messy flyback.

[@tommamai5492]

also can used it in all cabinet used K6100 i have a black widows with wg k6100 i can do that also ? because my monitor after play 3hours i see security game play i hear sound but monitor have no picture on screen ! where i can try to changed to stay on ? instal fan inside cabinet and close to deflection board to not heat to mush ? my tempest do also same after 2 hours playing screen put of but i heard the sound : ( let s me know thanks all

[@miamivicedotnl]

Hi John, just a little tip from the Netherlands. You should make a mark on that pot on your flyback to see if it's adjusted back to the same position to make the colors come back again. My guess the pots in your flyback are bad so why don't just replace your flyback? That's a ten minute job. Ok man, take care, hope you will fix this soon.

[@PecanPie1102]

I remember playing the tempest when i was 10 years old and it seems like the Refresh rate is off. Now that you have an Lcr meter check the diodes (on the board) All the diodes and especially the burnt part (right side) Nyc.

[@Duke_Togo_G13]

Omg! That damned monitor! John, how do you not lose your shit? Lol

[@Johnnyafc]

Part #5 John gets a Big Hammer 😱😂

[@owencrawford8416]

john heres an idea for the next video.. john cleans the popcorn machine lol grrrrr

[@trinitysingularityzombiech7836]

Owen Crawford make the popcorn machine great again!

[@PantherUK]

Overhead boom mic for the basement lol

[@TheArcadeguy]

it could be a bad fly back pots we have that happen at work allot how we temp fix it is adjust it where it looks good then we hit the knobs with hot snot aka hot glue gun and glue the pots

[@NotWatching666999]

Little Shop of Games in FL has Ghost Busters in stock.

[@dirtydon8661]

Dirty pots?

[@steve24822]

Maybe you need to get some hot snot on that pot?

[@illegalpizza]

Another great video as always!!

[@DreamGrandDragon]

this just shows how much this game loves to be on camera.lol

[@bobbyjack8033]

I know one thing if anybody ever has a problem with there tempest monitor there is a 99.9% chance its covered in this series. Im getting a full size in a couple of weeks and ill know where to go for answers! Sucks its given you so much trouble you know what I think it is but........ who knows at this point!

[@mrouse79565]

after you rebuild we should clean the popcorn machine

[@ugot2bekidding353]

lets fix the thing !! so we can move on to other cool stuff

[@CaesarNeptuneStudios]

Still my viewer mail is not been read yet.. Please John try to read mine next time!

[@Johnsarcade]

At this point yours is buried in my inbox. RESEND IT! :)

[@googleboughtmee]

Have you considered getting a different game

[@rmljr9106]

popcorn machine still not cleaned out

[@wizpin]

Give me the vector monitor, and replace that old $@## with a nice lcd :D:D:D

[@Retrogaming-yh1lx]

We need the obligatory Spy Hunter comment!

[@chadnordling4298]

Put Tempest in the garage and bring down Centipede.

[@crowbar2004]

#johnhatesmonitorrebuild lol

[@ed150arcade2]

sell it lol you need room for turtles and MK anyway 😉

[@JackLucasCaffrey]

Why Not Get A New Monitor? You Must Have A Monitor the Right Size In The Basement.

[@FeedEmHope]

jackcaffrey100 6100's are vector monitors. They are specialized monitors that only a couple dozen games used. Hey go for about $500 a pop.

[@Johnsarcade]

Yeah, the 6100 monitor is pretty unique. It's a color XY and I don't have a spare. The spare I did have is in my Quantum. :)

[@JackLucasCaffrey]

John's Arcade Game Reviews & Tech Ahh, I Didn't Know, You Better Get It Fixed!

[@RWL2012]

jackcaffrey100 Why do you start every single word with a capital letter?! 🙈

[@JackLucasCaffrey]

***** It's Just What I Do, I Know It's Silly!

[@DJThinK707]

My advice, get rid of it, wood grain cabarets are lame. If you must have Tempest get a real one!!!

[@Johnsarcade]

It is a real one. THE BEST ONE.

[@DJThinK707]

Im talking about a non cabaret.

[@Johnsarcade]

Yes, and I like the cabaret better. Same with Dig-Dug and Centipede. :)

[@mrouse79565]
