Question about Samsung LN-T4661F 46 in. LCD HDTV
When you have video display problems such as shadows and lines that go away after warming up, or come and go during viewing, it is usually the LVDS cable and T CONN board going bad. The screen can have one of the following or combinations of blurs, different layers of brightness and lines. It could be the back light but most of the problems with the LNT4661F have been this.
I had the shadow and line problem and replaced both the cable and board for $120 and that fixed my problem. Since I had the TV apart, I went ahead and replaced the capacitors on the power supply board so I wouldn’t run into the clicking problem that also affects this model TV. You can find the parts numbers for the LNT4661F cable and board below. You can find links to YouTube ( Part 1 & 2) to show how to replace the capacitors. Good luck.
