Re: Sony KDL-52XBR6 screen problems

Thank You dkneyle, I am looking for a replacement Tcon board, have not found one as of yet. I did locate an individual who claims to refurbish/rebuild your defective board, comes with a one year warranty for $130.
With the Ultra high def tv's out and on sale for the holidays, I'm not so sure I want to dump $130 into this old girl?

Hello all,

My name is Robert I'm an electrician and HVAC mechanic attempting to fix my Sony TV and hoping to get some assistance with trouble shooting a screen problem. Its a Sony KDL-52XBR6 that was manufactured in Oct. of 2008. The TV screen still has a complete picture but has segmented squares with vert/horiz lines in each box. I have a feeling its the TCON, the set disassembled, checked ribbon cables and connections at the tcon and around the complete lcd screen with no changes in picture. see photos attached. any help or advice is appreciated!

TCON is #404652ASNC6L...
