Re: Sharp Aquos PN-L703B With Horizontal Lines

Thanks Budwich.

So disconnecting the cables aren't good enough, I need to remove the tab drivers? What exactly do I need to remove?

Do you know what the brown ribbon cables on the side are for?

Re: Sharp Aquos PN-L703B With Horizontal Lines

I disconnected the blue cable one at a time. Picture 1 is both connected. Picture 2 is left side connected. Picture 3 is right side connected.

I'll leave the set on tomorrow until the flickering occurs (it doesn't start right away) to see if disconnecting a side fixes it....

Re: Sharp Aquos PN-L703B With Horizontal Lines

Thanks Budwich. Sorry for the delay, I've been really busy with the end of the school year approaching.

I think I found the side drivers. Should I try disconnecting the blue ribbon cable from picture 3 or the brown ribbon cables from picture 2?...

Hi Everyone,

I'm the IT guy for a small school in rural northern California where money for technology is very limited. I talked our superintendent and board members into investing over $3,000 for a 70 inch Touch Screen TV for our 8th grade classroom. It's been great for the last 4 years but a month ago, a very thin horizontal line appeared near the bottom of the TV. Turning the TV off and on again would sometimes get rid of the line but it would come back after a short time.

Now the line is flickering, making the TV unusable. I read about the common tab drivers problem...
