Most times when you hear this kind of sound on a TV it is because the flyback transformer is bad (from what I can remember anyway!). Its been a while since I repaired TV's, so hopefully someone can verify my info. The flyback transformer steps up the voltage very high which powers the color tubes. If that is bad, you will get the thunk sound. Also, if memory serves me well, there is a high power output chip that could be bad as well. Please, anyone who knows TV's, please verify for me. It has been years for me!

Multiple issue,power light flashes

Sounds like first loose connection on circuit board. I would first look around the relay this is what clicks. Then also the low voltage transformers. These problems are always concerns when set is moved or bumped hard. Try this first. Or it could be a heated issue.

Toy starts runs 10 seconds and stops change fuel filter now wont

When you tur the key forward do you hear the fuel pump running? You should hear a low hum for about 20 seconds near the gas tank and then it stops. If you hear this your pump is good. If it keeps running or you can't hear it at all it's bad or the main fuel pump fuse is blown.

Tv wont power up makes a noise but no picture

Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
