repair and replace lcd panel all and tv screen

I have a sony kdl52w4100 tv, and I turned it on the other day and the power lite came on green, a couple of seconds the standby lite came on its red, and it blinks 13 times stops and starts blinking 13 over and over. I called Sony and the told me it was out of warranty. They told me to call on of their contracted repairmen in my area, so I did. He told me my problem is the LCD panel is bad that a failed lamp inside the LCD panel. Cost of repair $2,800.00 dollars. Does anyone know how to replace and repair the LCD panel and change the screen? I found the very same tv with a broken screen that works fine, I changed the screen in the tv that I bought on ebay and used their insides, they same thing is happening with the new tv. Help

Thank you very much for your reply to my problem.

 

Larry, the problem is likely a CCFL tube behind the screen has gone out. I repaired my Sony KDL-40V3000 for about $80, as decribed here: http://forums.techguy.org/do-yourself-projects/926024-solved-sony-kdl-40v3000-backlight.html
