Red-24
Just starting my projector and my PLOG. I have most of the parts, but thought I would start with what seemed scariest to me. Stripping the monitor. I purchased and LG 1530s 15" monitor from London Drugs for $299.99 with a $30 mail in rebate. That's the best price I have seen for a 15" in town that actually has 400:1 contrast.

Here is the box.
Red-24
Here's the front of the monitor.
Red-24
And the back...
Red-24
The two back panels slide off.
Red-24
These four screws are removed first to take off the arm.
Red-24
Here the stand is off.
Red-24
These screws at the bottom of the panel come off next.
Red-24
Now gently pry off the front cover (next three shots).
Red-24
Still prying...
Red-24
And yet more prying.
Red-24
Here the front cover is fully off.
Red-24
Gently pry these tabs to get the back cover loose. There are four of them, two on each side.
Red-24
Here the back cover is off.
Red-24
With the back off, we can see the important components, the power, monitor connector, and controls.
Red-24
Another view of the back of the panel casing.
Red-24
Remove these four screws to loosen the back casing. Be careful as the electronics are still attached to it. Notice I did all my work on a felt cloth. Thank goodness for my other hobby of tabletop wargaming.
Red-24
Now all four screws have been removed.
Red-24
Carefully lift the back of the casing. The circle shows where the video connector is attached to the monitor.
Red-24
Here are the other connectors for the backlight.
Red-24
Disconnect the backlight here...
Red-24
..and here.
Red-24
Now disconnect the LCD panel.
Red-24
Here the cable has been removed.
Red-24
Here are the backlight connectors from the inside. If you followed my previous step, they shouldn't still be connected as mine were. I was still learning how it was set up.
Red-24
Here are the circuit boards and the screws to remove.
Red-24
Another shot of the circuit boards.
Red-24
... and another.
Red-24
Now to start on removing the backlight from the panel.
Red-24
Gently pry the metal frame from the backlight.
Red-24
Once the backlight is loose, it can be lifted from the LCD. At this point in time it is still connected via the circuit boards. If I had known, I would have unscrewed them first and removed the plastic. But I didn't so these are the steps I took.
Red-24
Carefuly pull off the plastic anti-static sheet where it has been glued to the back of the backlight. Don't remove it altogether because you can keep it where it is.
Red-24
There are some very tiny screws to remove here. You'll need a good jewellers screwdriver.
Red-24
Here the screw is removed and the backlight is free.
Red-24
Here the LCD is also free. I was careful not to let the circuit board scrape the panel.
Red-24
Here are all the component parts that I needed. The rest went back into the box.
Red-24
I then carefully wraped the LCD in felt, keeping the circuitry away from the LCD.
Red-24
I wrapped it several times.

That concluded my stripping of the monitor. More to come...

Excellent stripping guide.

Do you know what model number the LCD panel is? It looks just like the panel from the Benq FP531 I stripped. The panel is an AU Optronics M150XN07.

I need to find a source for a replacement panel, and if the LG uses the same one that may help out.

Good luck on the rest of your project, have fun!

Disregard my previous post.

Based on the great quality of your stripping guide and a some good deals on Ebay, I ended up buying a 1530s. It arrived today and I fired it up to check for dead pixels. It looks great.

I look forward to your upcoming posts, keep up the good work!

How is felt on conducting static electricity? I would think this would not be the ideal material to wrap a circuit board in.

Felt was more to protect the screen. I wouldn't recommend it for a circuit board, but it didn't cause me any problems. I just happened to have a lot of felt around from my hobby of miniature wargaming. ;-)

Here's the LCD and frame, control panel and circuitry sitting on the monitors anti-static bag.
Red-24
Next I used silicon to "glue" the LCD panel into the metal frame.
Red-24
Another picture of the silicon.
Red-24
Here the silicon is all around except on the bottom where the circuitry is. I also avoided getting any on the side circuitry.
Red-24
Next I figured out how to mount the circuitry. Here are the disassembled peices.
Red-24
Now I am measuring to see how deep it will be.
Red-24
I cut a peice of ply for the base and some other framing wood.
Red-24
I used some #4 - 1/2 inch screws.

A very nice guide. My panel is not necessarily working, so I might go get one of these LG's based on the friendliness of the construction shown in your guide. Did you take any pictures of it working in its un-stripped state?

Thanks much,
Eric
