Sony KDL-52XBR6 screen problems

[Tdi_flyer]

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 V4.5

I'd certainly reckon it's the T-Con. I had the almost same model of Sony Bravia and it was T-Con that had shut the whole TV down. Got a second-hand board that was defective. I had left half perfect and right half looked just like you have here. If you do replace the T-Con let us know how it goes.

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?

No, I wouldn't invest $130 into her. And I seriously wonder about claims of repairing T-Con board. I know some guys on this forum do fix 'em, but they are really serious SMT technology boards normally treated as a disposable item when failed. If I was you I'd put it aside and just keep a search out for a T-Con board; surely one will pop up on E-Bay etc eventually? Are you searching on the T-Con part number rather than model of TV? Remember, the T-Con is matched to the panel, so it will be used in a variety of models of TV.
