I have a sony tv (KDL-50R550A) which began to show pulsating horizontal blurry lines. The store recommends getting a new tv since this model T-Con board is built into the screen. Purchasing and shipping this part may cost just as much as a new tv. This tv is only about 2 years old. I plan to repair this tv for myself. I am requesting information that may assist in identifying the repairing this problem. Thanks.

Re: KDL-50R550A pulsating horizontal blurry lines
It is probably not the T-Con. Likely a bad panel. If you want to try a T-Con, you can get one on Ebay. The T-Con model is 6871L-3339A. The store told you it was part of the panel because Sony purchases the panel and it cones with the T-Con attached. Sony does not make the part and does not stock it.Comment

Re: KDL-50R550A pulsating horizontal blurry lines
That I know horizontal lines are not caused by tcon problems, it may be the tabs on the side next to the inverter board that connect to the lamps or the inverter itself, on the inverter it may be the transformers. Sometimes it may be the logic or main boar but it will never be the tcon board, if you replace it please let me know how it went.Comment
