The problem with the television is the lamp. It is faulty that is why the screen turns wavy in minutes.

I have a few horizontal wavy lines at the top of the screen when I first turn on the TV. They eventually fade after a few minutes. What's going on? Is this serious?


yes it is, your hyper board has bad caps and they will just get worse and worse. you can run it on an HD signal to keep it going longer but eventually even the HD will have the wavy lines too.. basically the hyper board needs new 10uf 16v surface mount capacitors, replace all those and your golden, but its a difficult repair, even for a educated and seasoned electronics tech, estimate from repair shop will run you $250-$550
if you can solder surface mount, you can fix it yourself for like $20
let me know if I can provide further assistance
