A bright white line across the middle of the screen indicates vertical sweep output failure. Check and repalce dmaged component/s in the vertical output section circuit. Check for any loose solder terminals around the the vertical output section circuit. Visit the site named 'Electro-help' for
more details. Click this link. View it in
"Timeslide" or "Flipcard" option, which can be selected
from the drop down box menu by the [Sidebar] tag, at the top left corner
of the display window. It will make
search easy. There are more than 1100 posts to different brand TVs now. Pull up
older posts there.
depending on which model roper dryer it can be a thermal fuse,high-limit thermostat,cycling switch,burned off wire in control panel,check each side of the heating element to ground and find 125 v.a.c. then on the side of the element that has low or no voltage on it to ground start at the element and back track the components leading to the dead leg on the element till you find 125 vac to ground and replace or repair component or wire,then you should get 240 to 250vac across heating element terminals
You haven't specifed nothing about the model number or brand name of your flat panel teleivison. i assumes that it to be a picture tube based one and posts this solution before you.
A thin horizontal line across the screen with sound output is OK, is the sympton of total failure of vertical sweep. This may be due to failure of vertical output IC or loose solder terminals of that IC. The vertical output IC will heat up while working, and repeated heating and cooling may make its solder terminals to get loose. Just open your TV, pull out the board that contains vertcial output section, turn it upside down, resolder all the solder terminals of that IC by applying a little more solder, without making any solder bridge in between terminals. Check the voltage to the vertical output IC also. If this resoldering method does not help you, replace the vertical IC itself with same type and number will solve your TVs problem. OK.
computer should always be connected with 15 pin VGA to DVI-I cable.
Select in menu input 1 analog RGB and adjust output resolution of Dell to 1024 x 768. this should work !
USB is only for mouse control with pj remote
This is definatelly a interference from a power cable. If any of your signal cables in the ceiling is closer that 5cm to one of those , you will get interference.
The Company that did the installation should know this and I would suggest you call them and tell them that they should sort it out. They should either move the cables or insulate them by means of conduit.
If you're using the VGA port, you'll see the banding because it's not really showing 720p, it's doing scaling (I'm not sure from what resolutions it's scaling). So, even though you're using VGA at 1280x720, the scaling is still going on and it's showing the banding.
