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...
