Re: Samsung LNT4669FX/XAA random horizontal line and restart issues
Not sure if anyone is reading this but I could use some direction.
I got a set of used boards in and started swapping. The only change in symptoms was when I swapped the PCB SUB FRC board. When I did this, I got the white screen - black with white light only coming in from the sides and warms up to be mostly white. This makes the power cycling stop. I have switched the T-CON and the FRC boards around every way possible. If I unplug the cable coming from the main board going to the FRC, and the power...

I replaced the caps and seem to have the same problem. It eventually warms up and stays on but has static lines.

Re: Samsung LNT4669FX/XAA random horizontal line and restart issues
I haven't gotten back to the TV to get pics yet. I ordered a set of caps and I also found someone on eBay selling all the boards out of this model. They should arrive this week. my plan is to swap the boards one at a time to see if anything changes. If the power board helps with the startup issue, I'm going to replace the caps. If the boards don't help the screen, I'll look at the tabs issue as well.

Samsung LNT4669FX/XAA random horizontal line and restart issues
Hi! I'm new here and trying to find some help. I've been searching and I'm just not confident that I've found issues that are exactly like what I have. I was given a Samsung LNT4669FX/XAA with known issues to tinker with to see if I can get it working. Apparently they had some service done to it at some point, but I'm not sure what that work was. I'm familiar with the bad caps issue and have done that repair on another TV before. I checked this one and all of the Caps look fine. So here are my symptoms:
1) When first plugged in, the red light flashes then the TV makes the startup...
