SOURCE: 12 little horizontal lines in Sony Bravia KDL-52W4100

we have the same exact tv and it is not even a year old. we are told that it is the display panel and it is a well known problem with this tv. we were also told that there is a shortage of these parts. they had 283 on order, but only received 35. you need to call sony and tell them that you have this problem. they should warranty this for you even if your tv is 3 months past the warranty period. since this is a well known problem with this tv, keep on them.

Testimonial: "It in fact was a part of the lcd panel...the t-con board. I was able to research it and bought a box of parts off of a tv like mine and fixed it. Ron"

KDL-52w4100 won't turn on and LED blinks 6 times


Bus clock and/or data lines low at power on. 6 blinks of standby light denotes this. Actually, it should be a motherboard problem. Your TV need a thorough checkup before confirmation. If you wish to get more details about the blinking codes to Sony TVs, check this link.

12 little horizontal lines in Sony Bravia KDL-52W4100


It's the panel. Mine took a sharp force trauma when it fell only 1 foot onto something very pointy (a cellular external antenna) and it looks like it got shot by a bb gun. And it has lines kind like what you are describing.

You can't fix an LCD tv with this kind of problem. You just can't. The LCD panel cost more than a new TV. I know I asked the local Sony Shop to just order me the LCD panel. It was over $900 on a $600 retail TV. I was going to replace it myself ... I fix laptops ... but not at that price. So far I'm just using it as it is, until I want to, and have the $$$ to buy another one.

Good luck on yours.

(a laptop lcd panel repair costed over $300 by the way on a $600 laptop with a few years age on it. I did it mainly as a learning experience. But never again.)
