Has this been resolved? I have a 1 slot doing  thing

I have the following for sale. All in working condition. I can ship within 2 weeks (as I go down to the U.S. about every other week). Buyer cover fees or send as gift.
110.00 - Vs. RBI
140.00 - Vs. Gooneies
125.00 - Vs. Top gun
250.00 - Vs. Tennis c/w main board

I'm also open to trades: uncommon > geo carts, tmnt tit, and sunset riders

I am looking for the following GD ROM for my collection
Dimm Firm Update Disk
GDS-0023A
GDS-0023C
GDS-0023E
GDS-0024A

Symptom
 main/sub colour look faded. Adjusting the colour pot has little change

Repair
 Replace the analog switch CMOS 4066 @ 1p/3p fix the problem

Symptom
 - Blue screen on sub side of pcb

Repair
 - Address line was giving odd reading (depending on when I turn the board on). All the eprom socket had continuity to the address line. Replacing the 6116 ram did not repair the issue. After checking all the logic it turn out to be a short on the PCB between address 11 and 12. I trace the trace between the CPU and socket 6D and it look intack on both surface of the board. My guess is its some how conducting between the board? I cut the trace and ran 2 jumpers. The board run now.

Update on board repair. Sorry for the lack of info as I fixed these before documenting things down.
Missing sound
-on both cases it was a bad LM3900 (5N,5R)

Missing red
-bad LM324 @1P (floating signal) after replacing that the red was a little wash out. Replacing the 4066 (2P) fix that problem

Blue screen
-bad CPU socket
-bad ram (1E,6E)
-broken Ram trace

Missing player 1 input
-bad LS240

Thanks for the info jumpman, ill keep that inmind for future repair. The resetting issue turn out to be because of my test rig (psone monitor). I have one board here that is still giving me a blue screen even after checking/replacing the CPU and ppu socket, 6116 ram, and 5533p-a ram. Next up is the EPROM socket and 8416 ram I guess. Is there a test EPROM for the Vs. Board? I'm slowly picking away at these board, on what little free time I have. I do have to say tho that troubleshooting is some what addictive.

[this turn out to be a mod to get the light gun working]

I just pick up 12 Vs board in need of repair. My 1st question which I think is an easy one.
- About half are missing 4 caps in the top right (control side) Any reason for this? --this turn out to be a mod to get the light gun working
- Some are missing sound (waiting on ic, to test)
- Some are reset (is there a watchdog cct?)
- Some blue screen
- Some white screen

Most have one side working. Any insights on these problem would be appreciated

Did you end up getting this working with the new ic401.

If it's a unisystem you want to populate the Sub side (right side of PCB if looking at part side with edge connect on top) and if your running SMB you need another cpu, RP2A04, or a jumper wire. Make sure you have the appropriate ppu for the game.

Reseat the CPU and ppu chips

On ep. 29 there was talk about super Mario 3 being ported to the Vs. Does this actually exist?

I have acquire 2 games. A darkstalker in a fair condition red Z-back and a steel falcons which I'm just gutting. I have a nanao ms8, wg7000, pentranic pc1027, and a hantarex mtc9110. I don't have room for all these monitor. My first question is which 2 are worth keeping, if they are working? (Picture quality and reliability) And which 2 would you keep in there current stat.
- Nanao ms8 is using a donor tube
- Wg7000 is chassis only and broken (missing pots and the big ceramic resistor broken)
- Pentranic work with dim colour and a bit of tearing on the lower right
- Hantarex did not turn on (no input hook up to it)
