PSone Board 'Folding'?

[Falco]

After seeing examples of the PSone screen LED mod, I think I agree with Hailrazer, the original backlight is more appealing to me. However, I still will need to cut the top of the board off to decrease area.

So this idea came to me. Would it be possible to cut off the top of the screen, flip it over to the backside of the board, and resolder the circuits with wiring, so that the backlight controller still functions?

Example:


Just tell me if I'm totally crazy.

It's possible... I think I remember someone doing it.. I'm not sure if anyone has posted information on how to wire it though....

[hailrazer]

I tried it and couldn't get it to work. Almost like there was a hidden trace I missed. Maybe I was just lazy that day though.

Technically, yes. It should be possible.

However, it might be easier to cut off the bottom. This is far more well documented as well.

Oh and btw, LED mods tend to look a lot better in person than they do on camera

[Falco]

I suppose it's worth a try, since I'll need to cut it to fit it into my case anyways. I can always do the LED mod after cutting the board, correct?

[snowpenguin]

Once you cut off the top of the board, the LED mod is a requirement unless you can manage to fold the board over and rewire it. If you don't fry the system but fail, the LED mod is still an option.

I want to say that Bacteria did this on his Turbographix portable. If it wasn't that one, then I'm almost positive he attempted it on another one of his projects.

[Kyo]

Just to confirm, correct. You should see a very, VERY dark, almost nonexistant picture if you have no backlight at all. Just add an led-mod and it's back to normal

Okay, thanks guys. Just wanted to make sure the process was salvageable if I screwed up. I'm going to try it once I have all the rest of my components and can test everything.

inverters tend to be a little finicky so if it doesn't work at first, try different gauge wire or something. making sure it's wired secure enough.

sorry for the late reply, but I found this in an old pm-exchange between techknott and me;

[Tchay]

sorry for the pseudo-bump but has anyone confirmed this method?

The above picture looks pretty reassuring. After looking at my mobo, it doesn't seem like that many traces would need relocating. Then again, I tried relocating half a GC mobo so maybe I'm not the best judge of that

[kibble]

In that pic, looks like the only thing really relocated was the transformer, which shouldn't be a major PITA if you decide to go that route. There's only a few traces going to it and as long as you keep the high voltage output intact and properly insulated from other things, it should be ok.

[snowpenguin]

Well actually, people have relocated the transformer before and had major problems. I don't remember if the problem was resolved or not, or what was thought to be the issue.

You can't make the wires too long. It will have to be fairly close to the original to work, but folding should not be a problem.
