Short Answer : You Need a VGA-lcd converter. Long Answer : Few years back (around 5 years) I was thinking in the same direction as i have 2 unused unserviceable laptops. On Googleing I found few solutions but they are either expensive or impossible for me. So try a search and find out. Though it is possible but in my view it is not feasible.

It was like a camcorder view

I'm not with my laptop but I think there is a function I'd rather use. Try lcd_out(1,1,txt10), it should rectify your problem and besides the function allows for manipulation of output. Check the mikroC help for more. If it yet doesn't work let me know by next week I will send you a full code.

YES, you can have a single 4700uF/50V. A set of parts would always be costly compared to bulk manufactured end product, let it be a psu. Many times, you get a laptop power supply at 19V and few amps , much cheaper. Generally for lcd and test bench supplies for digital circuits, you can have switch mode supplies, instead of Linear PSU. the rec

Hi, While you could make a custom lcd and keypad unit thats it linked to several others plus a master, the cost would be rather high, both in development time and parts. It seems more natural to use and link each player to there own laptop. You could buy a few secondhand laptops from any of the big dealers quite cheaply - they (...)
You have given yourself a hard task here. I guess you would need a fairly fast processor with lots of I/O. Should be possible, but there would be quite a bit of work writing the software. Not sure how laptop displays and standard lcd monitor connections differ. Possibly you may be able to use the controller out of a standard monitor to drive them.

Find a driver card or rip out an old driver board from a damaged desktop lcd. Unsure would you need the correct LVDS cable. There also a french website or forum that shows how to design a simple driver board using Analog ADC and some other logic gates. You would have search for that in google. The other alternative design your own driver board base

I step on my laptop at a wierd angle, and I think I jacked up my FL Inverter or backlight. Should I replace the lcd entirely, or should I try switching the FL inverter first.

Hello! Have you tried contacting the manufacturer for a data sheet? Self-made interfacing these panels to an analog VGA is pretty expensive and will exceed the cost of a complete new TFT monitor by several times. Your only cheap chance is to use the graphics board of the laptop where the display is mounted in and interface the graphics board
Normally, few would do such an interface, because every laptop gives a different interface. Good luck finding someone to design the circuit for you.
