I'm currently on my third LCD screen. I would have given up due to the cost of each screen but Ive already invested so much time and effort I can't. The problem with my first LCD was that my soddering iron sliped and hit a sound input jack on the circuit board- which I think might have destoryed part of the circuit. I beleive this becasue after instaling the LCD nothing worked except for a few lines on the LCD screen.
My second LCD screen I hoped would be better and decided not to sodder any wires to the ground connections on the circuit boards, instead I just tied wires to the ground holes. I also after taking apart the LCD monitor put the screen back inside its metal frame held in place by a thin bead of GE silicon glue. I bought the necessary ffc extensios online, and the whole time I had been working with an anti static mat and laytex surgical gloves. I'm pretty sure I ruled out the possiblilty of static shock due to its failure, however I noticed afer turning it on and the monitor not working that I installed one of the ffc cables in backwards.

The monitor had vertical lines and they moved according to how they should have when I tried to play a dvd, however it was missing horizontal lines and had gaps all over the screen. I'm not sure if installing the cable in backwards wouldve had made enough of a difference to actually destroy the lcd circuits.

I'm just having alot of trouble getting the LCD to work. I was wondering if anyone had any ideas as to why they could keep not working. I did install the lcd's in a metal frame with the cable connectors to the circuit boards touching the side and i thought that maybe that couldve casued them to conduct electricity to one another. Also, I'm know that silicon does'nt conduct electricity but could an addative in the glue conduct.

Finnaly, could some one reconmend a LCD monitor which I will be using for my third attempt, that doesn't require any FFC extensions. I saw the compatiable monitor list however I'm confused as to wether those monitors require extensions, because I know some of them due, including the planar monitor I just bought that was on the list.

Thanks

Well, for starters, what make/model of LCD did you use? This can make a difference in what things you need to do to make sure that it works.

Secondly, why did you need a soldering iron? This should not be needed to strip most LCDs, particularly those on the compatable list.

Most monitors shouldn't need FFC extensions, unless you plan on being able to access the control panel from outside of the projector. (This is a "nice to have" and I did it for my projector, but in truth, I set up the control panel once, and haven't touched it since.)

- The Planar monitor is PE1500
- The NEC monitor is MultiSync LCD 1550V

Supraguy,

In my experience control panels are not connected with FFCs, but with wires. FFC extentions are for when the circuit boards are directly in the way of the screen.
