This is a common problem and is either bad connections at the vertical Ic or a defective IC. Look for a small flat Ic attached to a heat sink with 9 pins or so. It should be marked LA7837 or similar. Resolder the pins and try again. If that fails, replace the chip. That should fix it. You may also need to replace some capacitors in the same circuit if the picture lookes stretched or otherwise off. The Ic should be labeled on the board as ICxyy. Capacitors in the same circuit will have the designation Cxyy. Change the Caps that have the same x designation.

Power ON DVD, horizontal lines running on the TV screen. How do I get the horizontal lines to stop running and for me to view the screen to possible reset the DVD player.


Check video plugin to see if connect good on both tv and dvd player. You might try unplugging and re plug. If that doesn't help you might try another plug wire not sure if you have rca or HDMI plugs.

The screen on the dvd player has lines going across it. This does it with or without the cd


The horizontal line connection for that particular line has lost contact or the diode for that line has burnt, in either case, a new LCD would be required.

Horizontal lines on screen.


Your unit may have a loose connection from motherboard to the display (video cable inside the unit), another distinct possibility is that the video processor chip is damaged or there is a power supply problem for the video chip (a bad electrolytic cap or similar somewhere around the video IC).
You can check the connection, but you'll need to take the unit apart, also check other connectors, but if it's an IC problem, this could get difficult or/and costly.

Please note that these are only suggestions and that the problem may as well be something else.

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.

You have a damaged LCD inverter board. The unit can now be used as a player only and you'll need to connect it to the A/V outs to see video clearly and without the lines.
