we are dealing with the exact same thing right now, but on a 40in. Samsung. It's 12 screws to remove the panel, 6 for the power supply, and 5 minutes of soldering to fix it if it is just the caps. Most of the caps can be had for less than 1.00 each, and rarely do you need to replace more than 2. It looks like you already googled the issue, check youtube next. They went bad on tons of sammy tvs.
