Sdm-S81 problems, ahhhh helpppp Options

[Neil4Real]

I'm somewhat of a novice so tell me if i say something that doesn't make sense, but I'm planning on using an 18 inch sony Sdm-S81 lcd. I've taken it out of it's frames and isolated the lcd screen. After looking closely, I realized that there is a board that connects to the top of the lcds circuits and the same board connects to the side circuits but the problem is that there is no flex cable ffc connecting the two parts, instead this flat chip blocks about a fifth of the back screen from any light getting in, and i'm not sure how i can connect this chip to the top and side without it hovering behind the screen, there are no flex cables, it's just this chip. I could do it if i find a male to female connector wire that would extend teh connection beetween the side and the chip. I'll attach a picture it's kind of hard to explain







is there wire that can extend that kind of socket?

That's going to be next to impossible to extend.

Sorry

The only way that you could do that is if you can get connectors that match, and put wire in between.

If you don't mind the risk of losing the LCD, (IE: It's either going in the projector, or the trash) then you could try to solder in an extension for the cable using an old IDE hard drive cable or similar.

De-solder the FFC from the board,
Tear a strip fromt he HDD cable with the approriate number of wires, and solder it to the board. (Easier said than done!)
Making sure to line up the pins correctly, re-solder the FFC to the other end of the HDD cable.

There are several methods that people can use to accomplish this.

I consider myself to be pretty good with a soldering iron, but I wouldn't attempt this unless it's that or the trash.

do you know what kind of socket that is?

i have no clue where to start looking for a wire like that,

the picture i put up is a female? connector, the male connector is on another board near the lcd, but if i could extend that socket i then this would be cake

No, I don't know what kind of socket that is.

Old hard drive IDE cables aren't hard to find.

Yes, I imagine that you could extend either side, and it would work fine.

That looks like it might be a Hirose SMD connector from their DF23C series. It may not be, it's kind of hard to tell from the photos.
No matter what it is, there is not likely an extension available from anywhere, because those are intended as board-to-board connectors.

One option would be to create 2 small circuit boards with the correct connectors on each, with the pins going to a cable on each (like the aformentioned IDE type cable)
but that gets really rather involved, unless you normally make your own circuit boards.

Search on Google for Hirose DF23C and see if one of the 20 pin models they have is the same. If it's not a Hirose, it is probably made by Molex, JAE, or one of the other connector companies.

It'd probably be cheaper and easier to get a different panel, and an 18" panel is kinda big and hard to work with anyway, in my opinion.

thanks for the tip man! i'll see what i can do; i normall don't do any circuit building but i'm really passionate about this projector, i just dont want to spend too much on it, but i want the best picture i can get so i might have to dish out some big bucks, if i can get that connection extended
