Re: Samsung 46 Smart TV-Bad T-Con again?

My TV model is a UN46D6420UFXZA. The panel model is shown in the attached pic.

I did spend a fair amount of time cleaning and checking connections and tab bonds. Didn't have any success eliminating a bad LCD panel vs a bad replacement T-Con board. I think I will try to exchange my T-Con board to eliminate that variable. I'm having a difficult time thinking my T-Con board and LCD Panel both failed at the same time.

Exchanging the T-Con board only costs me shipping and if I'm lucky it will fix it. If it is the...

Thanks for the insight. What is the best way to dispose of an LCD panel once I've cannabilized boards to sell on ebay?

Re: Samsung 46 Smart TV-Bad T-Con again?

A couple follow up questions:

If this is a bad LCD panel issue, does that mean that the tab connectors are failing?

This is a pretty thin panel, once I remove the edge trim, how do I get to the tab connectors to check them?

Wow, not the news I was hoping to hear.

I read another post about jumpers JP852 or JP854 being incorrectly installed on Samsung power supplies causing flickering. The fix was to cut the jumper. My power supply BN44-00427B actually has both of these jumpers. Could something like this be the cause of what I'm seeing?

Based on other poster's luck with Samsung service of not replacing failed panels on young...

Replaced the T-Con board on my 2-1/2 yr old Samsung UN46D6420UFXZA after screen went black. Installed the new T-Con and after 3 days, started seeing scan lines, ghost images, double images. Today, got black screen with horizontal lines at bottom. Recycled power and got more lines halfway up screen which then faded to black. Recycled power again and got full picture but picture is grainy. Thought my LED screen was bad but these symptoms make me think I got a bad replacement T-Con board. Can anyone help. Paid $1600 for this TV and really don't want to scrap it if it's just the T-Con board again....

Re: Samsung UN46D6420 Horizontal lines, now No Picture

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?
