Moving line through plasma and LCD TV's

3 wall mounted TV's one Plasma and two LCD's all linked together. all TV's have a faint horizontal line that slowly moves from the bottom of the screen to the top and continues to cycle through. When cable is disconnected and DVD player hooked up picture is perfect. Have changed out the cable box and checked the cable signal strength(good)as well as stretched out new coax cable to the TV's and the problem does not go away. Any ideas?

Re: moving line through plasma and LCD TV's

This is a very common Ground loop problem. The quick cure is to put a 2 prong to 3 prong adapter on the plugs which effectivly removes the ground from the circuit and stops your lines. Have fixed over a hundred TV's since the 60's that way.

Flat Panel TV WallMounting Instructions
Currenttrends Flat Panel LCD and Plasma HDTV's are making TV's thinner, lighter andmore powerful. Superior high definition viewing, affordable pricing with addedspace and energy savings are only just a few practical reasons for purchasing anew HDTV. With newer thinner designs, LCD and Plasma HDTV's are ideal for wallmounting. Wall mounting your television frees up space and adds a new elementof aesthetic appeal to your home theater. Positioning Before getting into any hardware mounting,find the best possible position to mount your television. Because wall mountingan HDTV is more of a permanent solution, careful planning is needed whenintegrating the television into your home design.
Furniture placement, overall themes, viewing angles, and the best audiopositioning are all factors that will help determine the placement of the LCDor Plasma TV.
Once you have decided the general positioning of the wall mount installation,cut out a piece of cardboard or wrapping paper in proportion the of theflat panel television. Next, approximate the placement by taping the piece ofcardboard or wrapping paper to the wall where the TV will be placed and mark itwith a pencil.
Preparing the TV Removethe stand from the television and lay the TV on its face. Locate the fourmounting holes on the back of the television and remove the bolts. Next, removethe mounting arms or mounting plate from the wall mount packaging.
To attach mounting arms, line up the arms vertically and parallel to each otherusing the mounting holes on the back of the television. Make sure that they arein perfect alignment and bolt the arms using the bolts and washer supplied withthe wall mount.
If you are using a mounting plate, simply line up the holes with the mountingholes on the television. Secure the mounting plate with the bolts and washersincluded with your wall mount.
Preparing the Wall Locatethe studs closest to the desired position using a stud finder and mark themwith a pencil. Remove the wall mount from the package. Line up the wall mountup to the studs within the center of the marked position you determinedearlier. If it is not perfectly centered, wall mounts can be adjustedhorizontally at a later time.
Using a level, line up the wall mount and mark the positioning of where hebolts will go. Drill holes into the stud about 1" deep, drill bit depends on the of bolts supplied with the wall mount. Bolt the wall mountto the wall with bolts and washers, but don't tighten down the boltscompletely. Adjust the position of the wall mount left or right to center it toyour desired position. When you are done, tighten the bolts the rest of theway. Mounting the Television Attachingthe television to the wall mount takes two people. Simply lift the televisionand hook it to the wall mount. At this point you can further adjust thepositioning horizontally to center it perfectly. Once the desired position isacquired, tighten down the screws that attach the mounting arms or plate to thewall mount.
