Re: Samsung UN46D6420 Horizontal lines, now No Picture

If I place the LVDS cable in it's "normal" place, I have only backlight on, no image at all.

That's probably not the right place then...

This is what I don't understand, the connector/cable could have a bad connection?

[tom66]

Re: Samsung UN46D6420 Horizontal lines, now No Picture

Due to how the LVDS is transmitted over that cable that is unlikely.

Re: Samsung UN46D6420 Horizontal lines, now No Picture

So, I should I try a T-con? That is cheaper.

I have ordered one. I will let you know how it goes.

Re: Samsung UN46D6420 Horizontal lines, now No Picture

This one looks almost(if not the same) as my problem and it looks like a T-con fixed it.

I have my un46d6420ufxza disassembled. What do I have to do to view the tab edge connectors on the led screen? Do i need to remove the black tape around the edge of the screen? What else after that?

I have LA40D550 with same issue as OP, horizontal lines/ghosting is flickering in top 2/3 of screen only. Replace T-CON, issue persists. Caps look and measure capacitance fine. Next step is to check ripple on PSU rails with CRO, possibly check ESR of caps (if I can find/build ESR meter) or more likely check bonding of tabs like https://www.badcaps.net/forum/showth...LN52A530P1FXZA

Any luck? I have the same issue with Vizio M501D and will be replacing the T-Con later this week.
