Thanks Madman,

I'm still writing up the step by step for the LCD strip...and will post soon...I still need to order the AC adapter for the screen before I can test it. Things are slow going right now...family and work don't leave much time. I hope by next weekend to have have it is a rough test stage...no box but to have it mapped out and have the focal measurements down....Then I can start building the box for it.

Wish me luck

Comming Soon

Hi Folks,

Sorry I haven't posted in a while. Several factors have been to blame for me not posting...the top two are:

1) fighting a cold

2) My laptop AC adapter broke , should have a new one my the 17th. 😀

As soon as I get my AC adapter I will put a step by step for stripping a PSOne screen. 😀

I'll post soon!

Back to the projector:

I hacked an adjustable AC 😱 and the Trav. A/C adapter that came with the screen to test it... It works!!! So it looks like this weekend I will be making a mock up projector 😀 I'll keep you all posted!!!

OK

Hey everyone.

Things should be going well for this weekend. AC adapter came for my Laptop 😀 I will post the step by step for the PS One screen strip tonight. I got an angled grinder from a friend and will be cutting up the slide projector case tonight. I am using it for rough mounting, and to hold the lens and lighting system in place.

Look for more info tonight!

LCD Time

Ok time for the LCD step by step.

My screen was very simple to strip. A few screws, a snip of the cutters and I was done!
These instruction were for my PSOne screen, your screen may differ…This is for info only…so if you screw it up don’t blame me!

 

[JohnA]

There were 6 screws holding the screen parts and 4 screws on the bottom inter-connecter.

There were 2 locking screws that attach to a PSOne.

First remove the locking screws
Then remove all the screws holding the housing together
I ended up stripping a screw head, so I had to drill it out…Oh what fun.

 

[JohnA]

You want to start with the bottom interconnect section (the part with the power, A/V jacks and the PS cable.

From the back separate the interconnect section, there are two small hinge screws that need to be removed.

 

[JohnA]

Here are the hinge screws

 

[JohnA]

Then separate the back housing of the LCD…It comes right off.

 

[JohnA]

You will see some mounting screw that attach the PC board to the back of the LCD…Remove them

 

[JohnA]

Next is the small mounting board for the front controls (Power, Volume, and contrast), there is a plastic holding bar that has two screws holding it in place, remove them and the front control board slides out of its holding bracket.

 

[JohnA]

Here is another shot of the front control board

 

[JohnA]

Remove the speaker interconnect jack (don’t need it) Just follow it from the speakers to the main PC board, it will terminate to a small plug that you just pull out.

I know the picture is bad 🙁 but oh well!

 

[JohnA]

Now we move on to stripping the LCD itself. Don’t worry it comes apart very easy!

There are 4 screws that attach the Main PC Board to the LCD remove those, now you can remove the LCD…it will still have the backlight attached to it.

 

[JohnA]

There are two wires going from the PC control board (the one that was attached to the back of the LCD) to the backlight, these need to get cut. They are the ones with the rubber boots on them.

 

[JohnA]

Then you will see some small screws holding the back light to the back of the LCD, remove them, there will also be a ground wire going from the LCD frame to the copper EMI shielding, you need to cut this also, now gently pull off the backlight, you might have to use a little force because of the double sided tape

 

[JohnA]

You’re done!!! That wasn’t so hard!

Now you should have the LCD, the PC board, the small PC board for the power button, and the A/V ports.

 

[JohnA]

Time to start on the mock-up! This is when the madness sets in!!!
Wish me luck!

More to come later!
