The screen has flickering color snow on all inputs. It even shows when the TV has no inputs connected. I posted some pictures here:

It looks like there is a defect with the main control board you will need to get it replaced.
Hello williams4895,
I have seen this problem before, it is caused by RF interference. For it to be this severe it appears that it is an internal RF issue which means that there may be problems with high frequency signal decoupling capacitors used to decouple RF/IF signals from the power supply that feed said such stages of the TV. This is going to require that you use an oscilloscope to determine if RF/IF signals are present on the power supply rails. However this is looking like according to your pictures as the problem I am describing. In this case it will be a slow process to determine the cause of the interference, since it may involve more then capacitor, and maybe you catch a break and it might be due to one decoupling capacitor.
I hope this helps,
Thank you,

Thank you, I am experienced in electrical repair (soldering, etc...). However, for this equipment, I do not know how to check the 3 items you mentioned. What steps do you recommend?
Great. I have repaired electronics and another TV using instructions from FixYa expert. I have most of the tools and can get the ones I dont have. How do I start?
I posted the pictures to the same location as my original pictures. I posted pictures of the power supply and detailed pictures of the mainboard. There are 2 boards that you can see on the side of the main board of the TV that I didn't include. They are under a cover that I didn't remove. Please let me know if you need pictures of these also.
Thanks,
Shawn
I would like to resolve this quickly. Will it be easier to replace the mainboard (or the power supply board)? If so, where is the best place to buy one?
