My tv turns on lights up but shows no picture. And I hear fuzz or white noise coming from the speakers which I can control how loud it is with the volume control on the remote. I just replaced the main board. Anything else I should look for? nothing on any of the other boards looks bad or unusual.

matthewdgriff the buzzing could come from an inductor or a transformer. You want to go ahead and remove the back of your TV and take a look at the boards for obvious damages components. Check for leaking, domed looking capacitors and burned looking components. Take a couple of good pictures of your boards and post those with your question. Use this guide Adding images to an existing question for that. It will allow us to see what you see.

I’ve just replaced the main board on the tv. And the buzzing sound is coming from the speakers themselves I can turn it up and down using the volume control on the remote
And the screen light comes on but I have no images
Okay so you are saying that your backlight comes on and buzzing from the speakers (should have said that in your original question) Have you measure the voltages from the power board to the main board? Make an assumption that the main board is new and in good working condition. Pictures will still help
