Black Horizontal Lines on Screen

hey jeff i read your post noticed i have the same problem as you my tv is samsung ln46b650 7-8 monts old barely use it, i have multiple thin grey lines running across my tv right too left, i was wondering if you have resolve your issue about your tv any update about your tv?

Had local service guy come out and take a look at it. He did some messing around with some patterns in the service menu for about 5 minutes, and said looks like it is a bad LCD panel. He is on vacation this week but said he will be ordering a new panel and will come back to swap out the panel(1/2 hour job) in another week or so.

So hopefully that fixes the problem, but I'm not happen about swapping the panel for a new one. I think they should have swapped for a new TV since it's only ~10 months old and still in original 1 year warranty period. I will let you know if it works!

Hope you can solve your issue also. Let me know how yours turns out.

sorry too hear that, it would be nice if they just replace the whole tv for a new one, i called samsung today and they gonna send a service for a my tv, waiting for them too call me in about 2 days too book appointment, hopfully they fix the problem, did your tech say anything about what was the problem? ill update you once i know my problem okay ttyl thanks for the reply

Mike,
He just said it was most likely a bad LCD panel, but he didn't sound very convincing. I hope he knows want he is doing. Let me know what your service guy says. I'll let you know when he swaps the panel and if it works.

Service guy finally came today and replaced LCD panel problem is solved!
No more horizontal thin lines up and down entire screen every 1/4 in or so on left side of screen.

Good thing too my warranty is up next month!

my service guy swap the whole lcd panel in 20 min's max like nothing, no more lines for mines too, but im gonna extend my warranty for 2 more years just in case anything happens.

Who are you using to get extended warranty? I would like to do that to if possible. Are you getting it through Samsung or someone else?

Thanks,
Jeff

i havent done it yet, but i think u go to samsung.com and register

Hi Speedrock84 I have the same problems, thin Horz. lines. When the tech. replaced your panal did he use all of the orginal circuts card from the old panal. Main Ckt borard, power supply and t-con board. I belive there were three (3). Did the panal come with new t-con board. It`s the one in the center.
Thanks Jim3722

what he did was replace the whole lcd panel, and he replaced the circuit thing where you plug your usb and hdmi cable he replaced that too.

This is a followup on post 3/7/10. Tech replaced the LCD panel w/t-con board. Problem with Horizonal line was resolved. The picture clarity is not as good as before and the picture is not as bright. I asked the tech if Samsung repair record was good. He stated that it had a bad repair record. He also stated that Vizio had the best repair history followed by Sony.
Thanks Jim
