Hi!

As the title already says I have a problem with my Virtual Boy whereas the right display/array is completely oversaturated.

As far as I recall I have this problem since I bought the console some time ago but in the beginning it was only from time to time and I thought it was either from rom problems with the flashcart or problems with the ribbon cable. Well, by now the problem is permanent with both original games and flashcart and soldered cables so the origin must be somewhere else. =)

I also tried to take some pictures which turned out not really well but I guess you can see what I mean. Especially if you look at the VB squares of the calibration screen and the item boxes of Vertical Force you can see that the intensity is on maximum everywhere.

Maybe someone here has already encountered this problem or any idea from where it might originate from? Thank you! =)

Looks like a classic case of “glitchy displays”. This is what happens when the glue starts to let go. I can fix it for you, since you seem to be located in Germany, just send me a PM and we will get you sorted, if you want of course!

Well, actually, both are soldered displays I got from you some time ago. =)

That’s why I highly doubt that it’s a typical glitchy display problem. 😉

edit: Okay, you are right nonetheless. =) Seems I have to check the solder connections because it works when I press on the cable. Didn’t expect that with a soldered cable. ^^

Well, could be that one connection wasn’t good in the end, just send it to me and I will fix it without charge, only shipping is not included.

That definitely looks like one or more of the three “BRT” lines are either disconnected and floating high, shorted together, or shorted to VCC. It causes whichever of the three red shades affected to be permanently on (whenever the pixel isn’t black), which is as bright as the LED can get.

I’m assuming you’ve tried reseating the cables as per this post, right? If not, it’s worth a try before you send them back to TheForce81. You might also want to make sure a wire didn’t get folded, shifted, or broken at the end.

Also – and I’m talking to everyone, not picking on freaka-zoid – if you’ve had someone solder your VB displays, you should contact him directly if you ever have a problem with them, rather than posting about it publicly. You’re bound to get better tech support from the technician who originally did the work, right? 😉

Nobody’s perfect (which is why neither TheForce81 nor myself charge for “retouching” displays that fail after being returned), and it’s a bit embarrassing to have your failures plastered all over the forum, no matter how rare they are.

Thank you for reminding me about that again RP, today I had recurring horizontal lines on one display, when pulling the cable out slightly, the problem disappeared.

I have seen that a lot of times lately, but again, it could be a loose connection. If so, just contact me and we’ll get it sorted, only have had a problem with one display once and that happened right away when the person put his displays back in the VB, got that fixed as well.

Thanks for the additional tips, RunnerPack.

As for your other remarks in general I fully adree with everything but I want to point out some things (no criticicing/defending/whatever – I just want to clarify ^^):
You are completely right that considering problems with the displays I should contact the one whom I got them from. But as you can read in my post I didn’t even think that the problem could have originated from the displays (rather maybe the circuit boards or something like that – although I should’ve checked at least before opening a thread…). This was on the hand because I would’ve expected stuff to rather disappear than appear and since I’ve encountered this from time to time since I have my VB. On the other hand this is because the displays were already soldered and I think that TheForce81 did a great and clean job there (which you can see by mere eye already). =) And thus of course it was in no intention of me to show a “failure” of him or anything like that (which is needless to say but you are right that it could unintentionelly have turned out this way in the end) and I would definitely recommend him to anyone in Europe. 😉

Well, as for the displays: I tried to locate the broken connection by multimeter but this did not quite work out with these small connections. So I decided to reapply tin to all connections. ^^ The display is now working again and appears to be stable. =)

So, I’m off playing! 😉

Good to hear you got it solved by retouching the display, though I wouldn’t recommend anyone to just try it unless you are sure you know what you are doing (as I read, you are of course 😉 ).
