Instructables
So one day I had an idea, "What if 2 broken different screen size TV's have the same interface for the LCD panel, would I be able to make one that is working from those two?"
So I checked this theory...
and the result is: YES IT IS POSSIBLE


It is advisable that the TVs that are going to be combined were at least the same brand, that way your pinout should be some what similar. 

Unit that I worked on were both made by SONY.

The logic board donor is 32" Sony KDL-32M3000    http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&partNumber=KDL32M3000

Recipient is 40" Sony KLV-S40A10    http://www.welectronics.com/tv/SONY-KLVS40A10.HTML

So the little one had a broken panel but everything else was working fine. I even have a remote for it ;-)

The big one had a bad logic board where 5V stand by turned into 2V and 17.5V into 8V. The power supply and the inverter board were OK.
I couldn't upload videos to this instructable so I am posting an external link to them.

Now let the madness begin...

Step 1: Check if LCD cable is compatible

the first thing you should do is check if the components are compatible.
How I did that is by turning on the little TV and connecting the LCD cable from main board to the panel of the big TV.
The very first hint is the LCD cable should be physically compatible.
After that I put 5VSTB into POWER-ON which turned the backlight ON.

If signal is compatible to the LCD panel then you should see the picture.
What I saw is the SONY logo at the loading state.
That is the clue!

Step 2: Taking apart Sony 32"

Picture of Taking apart Sony 32
Took a little one apart and discovered that the voltages from the power supply are different so I will have to move the PSU with the main board.

P.S. Originally I thought I could use the PSU from the big TV to power the new main board but it didn't work out.
Brilliant.
Resilient.
Ingenious.
Inspiring.
Where did you get the donor TVs?

That's amazingly awesum, but on a slightly different note is there anyway I could use that 1st image for an art project?
