I'm planning to go to Too Many Games... hopefully Saturday afternoon (I'm traveling for work next week... I don't know when I'll get back yet).

I talked to morintari, and I believe he's going to try to meet up on Saturday too. Maybe we can all get together for a quick PlanetVB gathering. :)

Yep, the project is definitely still alive. The link shell needs just a couple minor tweaks, but I'm trying to get the redesigned USB link up and running. Just been short on VB time lately.

Good evening DOGP
Do you still repair any virtual boy system.?after reading all your miracle work i was wondering if you could do a miracle with mine?it a bad case of glitchy line one one side and also seeing double.hope you can help

my email malicedoll79@gmail.com
thank you

Sorry... unfortunately, I don't do repairs anymore. Both RunnerPack (USA) and TheForce81 (Netherlands) offer repairs, and do great work though... so I'd message one of them (depending where you live).

PS --- where does one get a "fiberglass brush"?

They used to be easy to find (I had gotten them at Radio Shack and the auto parts store)... but in the last few years, it seems that most have either gotten rid of them (or, in the case of Radio Shack - gone out of business), or changed to a nylon bristle brush (still calling them "fiberglass"). The nylon brush is completely useless.

The last one I bought came from an art supply seller on ebay (who I just checked isn't selling on ebay anymore). But again, you gotta make sure it's actually fiberglass and not nylon.

Here's a video of someone doing a solder repair, to get an idea of what's involved: https://www.youtube.com/watch?v=RQC4c9Lylg4 .

You can see that the cable is attached the whole time. In that video, he burned away the coating on the cable. I personally don't like doing that, as it applies too much excess heat IMO. I originally used NaOH, though anymore I use a fiberglass scratch brush to carefully peel back the lamination, leaving the copper exposed.

You can see pics/details in this post: http://www.planetvb.com/modules/newbb ... t_id=24012#forumpost24012 .

So when the displays are "dead" and submitted for repair -- the flex cables still have to be dissolved off of the LED pcb's?

No... when they're to be soldered, they just need a little bit of the copper of the cable exposed somehow (heat, abrasive, or chemical), so the solder can bridge the connection between the cable and the display. But if you were to use Z-axis tape, you would need to remove the cable from the PCB, since the new tape would have to go between the PCB and the cable.

We've talked about that stuff in the past... I think that's similar to what they used at the factory (which obviously fails over time).

It could probably be used to fix a VB display, but I think you'd want something to continue applying pressure (bracket and foam or something) to prevent it from coming undone again (the datasheet suggests that, and it seems to work best when you press on it).

The other thing I don't like is that peeling the cable off the display is a bit risky. It's very thin and tends to curl, and sometimes leaves copper from the cable attached to the display. I think you'd want to chemically remove the old adhesive, rather than simply peeling. But you'd need to make sure you didn't get any chemical on the clear window. And then you need to line it back up and re-attach.

So... IMO, it's an inferior fix to soldering, and not any easier. I have some of the tape, and plan to try it if I ever come across another detached display cable, but haven't yet. If you give it a try, I'd certainly be interested in how it works out.

He's probably referring to the Dragon Hopper that was on half.com . I'm assuming someone put it up as a joke or something... AFAIK, it's always been listed as "out of stock".

Pins 1 and 6 are numbered on the motherboard... it's the black board sticking up on the right side of this pic:

Okay... IMO, the next step would be to see if you have +5V. That regulator is inside the VB on the motherboard (small board sticking up, labeled U8 DC-DC-VUE).

Open the system up, plug your controller in, turn it on, and check whether a dim red light is glowing on the regulator (you might need to be in a dark room to notice).

The pinout of the DC-DC-VUE is:
1-Vin
2-GND
3-PowerGood
4-no pin
5-Vout
6-GND

You should measure the voltage across 1 and 2 to confirm that you still have 8 or so volts. And then across 5 and 6 to see whether you have 5 volts.
