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

Wavy horizontal lines across the screen


It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

Wavy lines


Are the wavy lines horizontal or vertical? If they are horizontal and up near the top of the screen it could be 60HZ interference from a power cord running over the cable from the DVD player to the TV. There could also an internal breakdown of the shielding by the power supply of the DVD player. If the lines are vertical it is likely the cable or maybe the input jack on the TV. Could be a number of things.
