Hi everybody from Spain!

I've just purchased a second hand 15" tft monitor for building my first proyector. The problem is that the monitor comes without the connector, basicaly the cable has been cut! Now I have to buy a 15 pin VGA connector and solder the 10 cables now amputated smile.gif
I've tried to find out the diagrams on the net but I have a lot of questions, are the TFT/LCD and CRT connections the same? I have to look at the VGA standar or VGA VESA diagrams?
I only see the color wires, there are 3 thicker wires: blue, red and grey, and 7 thin wires: black, brown, grey, violet, red(or dark orange), yellow and white. It would be great if somebody sent me the pinout or the way to remake the connections.
The monitor is a HEAD (PROVIEW, model FE-561)
Another posibility is that I can cut a VGA conector from a wasted CRT monitor from my work, hoping that the colors of cables will be the same, and if the colors are the same, how can I be sure that my monitor or vga card won't burn on the first plug? Can I take voltage/resistance mesurement on the pins with a tester?

Any sugestion or comment would be very helpfull for me!
Thank you very much.


P.S.
Serching on the net I have found a site explaing the way to directly conect a vga pc card to a tv via standar SCART conector without any aditional hardware or circuitry. Now I wonder if is posible the vice-verse way, I mean if is posible to use our projector to conect, for example a home DVD or a sat decoder.
Here is a link showing how to do it, is in spanish but the graphic diagrams will be understanded for

First of all, thanx for helping.
The problem now is how to recognice each wire to sold them to the wright pin.
Anyway thank you for the information, I have printed it and i'm comparing it with some Proview diagrams (not my model but similar) that i have found.

I finaly did it!!! Miracly i have found a similar model eschematic diagram on the net, the Proview AY-565. Without the scheme would be almost imposible, becouse most of the cable colors are diferent.
I'm realy proud of myself!
Next step, to buy the diferent parts for my projector.
Could you advise me guys? what to buy if i want good quality? Pro fresnel vs standar fresnel? pro lents vs 15" lents? I mean, I think "pro" are for 17" or 19" LCD TFT's. is this true??
Bye!

good for you, now we'll know who to come to for vga questions wink.gif
well, how big of a projection do you want? are you going to play hi-def stuff? just dvds?, you can use the pro lens with a 15" screen if you want..handy if you have a long narrow room, the throw is greater withthe pro lens

Yeah! since my problem I've read a lot about VGA, so it would be a pleasure if someone needs help.
As you know my LCD is a 15" size. I have a litle flat and a lack of big rooms wink.gif is it enought with 4 meters from wall to wall?
I think it won't be a good idea to spend my money with the pro kit.
Can I get good contrast/color/definition only with the basic kit?
Which will be the resulting screen size on my 4 metres room?

If your stuck with a 15" LCd then the standard kit will do everything you need. If you want to eventually step up to a 17" LCD, you can still use the standard LL triplet and get some replacement fresnels, although you'd have to make your box big enough to accomodate this. The ultimate in quality is the complete pro kit.

Rule of thumb, 1m from the projection lens to the wall will give you a 1m diagonal projection. This will vary slightly depending on your chosen method of build.
