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.
