When I turn it on, it makes a buzzy noise but nothing else., no picture or tv sound.

The set has a high voltage problem, "the flyack transformer is defective" It generates the high voltage in the picture tube and with the help of the video circuits it produces a picture. It is not cost effective to repair the tv, cheaper to replace.

Having a big yellow spot background in the middle of the picture.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Big black screen in picture

You have the CC (closed captioning) turned on and it is set to text mode. Look for a button on your remote labeled "CC" or go into your TV menu and make sure the captioning selection is set to "off".
