Samsung LCD TV brief flash of horizontal bars

[Bfritz97]

I have a Samsung LN-T4071F LCD TV with the following problem:
Occasionally (maybe every few minutes, sometimes more) horizontal bars will briefly flash on the screen (for a fraction of a second). The bars usually look like sections of the picture that jump out of place in the vertical axis. Sometimes the bars are thin. It's hard to describe but hopefully I've given a decent enough description to start with.

The problem doesn't seem to occur for the first few minutes the TV is on.
It ususally occurs in bursts (ie it will happen a few times within a short period of time)

I read through the badcaps basic TV troubleshooting guide and various discussions around the web that led me to suggest it was the TCON board, but the problem persists.
I haven't found any discussions specific to this issue.

Thanks in advance

Part of the image ghosting\copied over another part...

I guess bad mainboard, t-con or panel, but I don't know which it's likely to be.
Someone else should know what it is. I put the picture here so it's easier for people to see.

That it doesn't happen in the first few minutes suggests to me an overheating problem in some component. Freezer spray may come in handy to track it down.

Re: Samsung LCD TV brief flash of horizontal bars

The issue is usually far too intermittent to really use freeze spray. It usually occurs for a fraction of a second and not too often. Also I've already replaced the tcon board, but with a used one .

The input is ps3 through hdmi. It is all I have but works fine on other tvs.
