Question about Samsung LN-T4061F 40 in. LCD HDTV

1 Answer

Samsung LN-T4071F picture starts clear, then gets grainy as the TV stay on.

I have a Samsung LN-T4071F. When I power it on, the picture is strong and clear. After 10-15 minutes though, the picture begins to get grainy, and gets continually granier as it stays on. What could be the source of this problem and is it worth fixing or should I invest in a new TV?

Sounds like a fault with the connection to its T'Con board to display panel. Check for any loose contact at the both ends of connection sockets to LVDS cable. (Low Voltage Differential Signaling) {that involves transferring a signal on a wire and its opposite over a second wire to allow the receiver to reconstruct the signal by difference}. Re-seat all the cables that comes to and goes from the T'Con board once, and check. Contact any service technician. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view. It will make surf easy. http://electronicshelponline.blogspot.com/

a0b65409-5b20-4df7-a509-196d94a9ef02.jpgI haven't worked on that exact model but your symptom is similar
to others of that series. The filter capacitors tend to age and bulge up on the top. They are fairly cheap so consider changing all of them in that area.

I was moving my samsung 40 ln-t4071f and cracked the screen. Can i buy one somewhere and could i replace it myself?


To replace the screen is going to cost about at least $500.00.
I will try to sell the tv as is for parts. You can probably get about $100.00 . Thats how much I buy them for.

It would be too costly to fix! I recommend giving the set to your local waste management program.

This normally causes by failure of power supply board. Some time it causes by failure of inverter board, in this case you can see the picture moving on the dark screen as it has no back light.

Unless you are watching an actual hd station this is how it is going to stay for you. Sorry your real quality comes in when you are actually being fed a true 1080 I signal not some upgraded 480.

Thanks
