The internal power supply may have failed.

Does the screen have a double image? or is one side of the screen darker and has a delay? If so, your LCD panel is failing, common problem with older Samsung LCD's. I have the same model in my dining room that had a double image, fixed it by taking the panel apart and applying thermal pads on top of the panel tabs. The set works like a champ to this day!!!

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need further assistance so that I can help you further.

check your power cables

You will need to replace all the capacitors in the output side of the power supply. It is possible you have other bad capacitors that are not bulging at the tops. The power supply generates a voltage used by the the video processor on the main board. If this voltage is out of whack, it can affect your video. I would recommend you check all power supply voltages for accuracy and ripple.

We may neet to begin contacting the attourney general. Seriously we may all have to write letters. I am willing to organize this if others post a willingness to engage in this process. Samsug customer service told me that what people report on the internet has nothing to do with Samsung. I explained that I was not wanting to report to the internet, that I was calling to report my number to them. It took some arm twisting to get her to give me a contact on who to report the problem too. They won't listen to internet blogs and I don't blame them for that. However, I was reporting directly to Samsung and they did not want that too happen either. That is not ok. We need to get the attourney general involved. Who is with me?

Check whether CCFL lamps are good or not. Check whether the newly replaced back-light inverter functions well.
