Sony kdl-50r550a. Horizontal strips come every 4-5sec.

Hello.
1st of all - thank you for reading this.

I bought this tv 2 years ago, and for 3 months we travelled with my wife.
We came homeand found what there is a horizontal lines with slight disturbing in the bottom of the screen. They appear for 1 second and disapear for 4 seconds.

I dismantled back panel and disabled ribbon cable which connect t-con board with man board (where hdmi inpunts is placed), turned on tv and lcd panel turned on without horizontal strips. connected t-con back again and those strips flickering appeared again on black.

So my question is next - changing t-con will help me or not?
Thank you in advance.
And sorry for my english.

Horizontal lines for the most part does not represent a T-CON Bd problem. I would think you have a Tab bonding issue. Perhaps if you post clear pics of the backside of your set with the back removed we may be able to offer better help.
