Samsung LN-T4061F All Inputs Pixelated

[Scoto]

Hello Everyone,

New to the forum here and I was just looking to get some input on a TV i got from a friend that I wanted to attempted to fix. As the title states is a samsung ln-t4061f and all of the inputs have no clarity and are completely pixelated. I have attached a photo of how it looks on a TV receiver and can also provide shots with other devices as well.

I was wondering if anyone has come across this before as I was seeing things about Tcon boards and how these TVs are also known for the Samsung capacitor issues back in 2006 - 2009. I have yet to open it up but just thought I'd ask here first before I go and start taking it apart likely tomorrow (Monday).

Thank you to any and all who read this and respond.

My initial thoughts would also be Tcon.
Doing a quick search on the forum does appear to show this set as being quite problematic.

I'd also think it is the tcon.

Can you post a few good clear pics of the inside of the TV?

Hello everyone,

Thank you for the quick replies and yes I will get some clear pics of the inside once I open it up I just wont be able to get to it until tomorrow.

Unfortunately during my searches I wasnt able to find anything that showed this same level of distortion or picture.

If it is a tconn board do any of you have recommendations for where to get one?

Hello again,

I have pulled the back of the unit and there doesnt seem to be any capacitor issues that I can see visually. The Tconn board at the top though does have a different smell than the other components which makes me think something may have fizzled out to cause the problem I am having.

Here are the pics of the mainboards and the Tcon. Let me know if you want pics or information about anything else.

Thanks

Hello Again,

I went ahead and ordered a new TCON board and have since installed it and it would still seem I have the same issue although now there appears to be a black line through the screen as shown in the attached picture.

The exact same picture discoloration appears with this board as well as the old one so I am not sure if anyone else has any other thoughts on this. I will not be heavily investing in it at all I just wanted to get some other ideas and perhaps close this out.

Thank you

Can you get a menu up? could be your mainboard.

Re: Samsung LN-T4061F All Inputs Pixelated

What is the number on the white sticker on your mainboard? it will start with bn94.

Hi nomo,

Thank you for replying. I can get the menu as shown in the picture below antd he board model is bn97-01835a.

This is the board that all my inputs are connecting to. I presume this is the one you wanted correct?

press a bit on the main IC (yours has a heat sink) on the main board and see if there is a change. You also can try to clean the LVDS ribbon cable and heat up the main board with a hair drier and see if there are any changes.

Should be a white sticker on the board, what's the numbers on it?

Did you try a factory reset? try this: With the TV on, press and hold EXIT on the TV remote for 10 seconds, should bring up the reset option on screen.

Hi guys

I haven't tried those things yet but I will try tomorrow. As for the board here is a picture of it you can see the white sticker on it. It states the number that I provided.

Also friend never gave me the remote so I will have to try it with a universal one that I have. Hopefully it works.

Re: Samsung LN-T4061F All Inputs Pixelated

There's a new tcon (well used) in there from a verified eBay source and it didn't change the screen image. It's why I'm inquirers about other things like the main board now.

Re: Samsung LN-T4061F All Inputs Pixelated

Ok, post 15 is a mainboard.

Re: Samsung LN-T4061F All Inputs Pixelated

Yea thank you I saw that and I did verify the board number with the one you posted and they do match. I was looking at a different sticker on the mainboard.
