Samsung picture flickers

I'd look at a bad panel, the defective panel damaged your main, replacing that got it working somewhat but if it's on very long I'm guessing you will damage the main board you replaced. Try unhooking the ribbon connectors one at a time and see if half the picture works ok, if so you definately have a bad panel

how extended is that warranty, and what does it cover? Sounds to me like a classic video controller board about to fail.

No the cost of repair will shock you.

How to fix Samsung LN46C630 screen flickering issue

appears other people are having the same issue with Samsung TV's.

Try calling Samsung or wherever you bought it from.

I've been dealing with Samsung on this issue.

We got a 40" LCD in October 2010 and it started flickering January 2012.

Changing it from 'standard' to 'movie' helped (natural and dynamic flicker)

Then it started flickering in 'movie.'

I called Samsung and told them this issue is all over the internet. They agreed to pay for repair, parts and labor, even though it's out of warranty.

The guy just left and this is what I know. He said that in the 46" and larger, the issue is a jumper. In the 40" and, I think, smaller, it's the panel. He's ordering the panel and will be back to replace it when it comes in from the warehouse in CA.

Try calling Samsung and good luck!

hi if you keep having problem ring the place you brought it from see if they can help thanks

Reset satellite data and the flickering went away.

is the picture clear when on? if yes, does the screen go black after a few seconds. if yes, sounds like you need a back light inverter!
