Hello I'm having troubles with my sharp tv. It seems that on the top of the screen the color seems to go across in waves like a flutter is the best way I can describe it. Can someone help me trouble shoot this. Looks like the back lights work and compacitors look ok. Could it be the t-con? Please help

i am assuming the drive E:/ refers to your dvd or cd drive, if so it may be faulty and need replacing, but the only thing to try and resolve it other than having to buy a new one is: control panel>device manager(or system icon)>hardware tab, look down list for Cd/DVD drives, click + sign right click on drive and select uninstal. Restart pc and it will install itself, see if it works and shows in my computer, if not the drive needs to be replaced.

SOURCE: kolin color tv,degausing problem.

Degaussing coils do not work on LCD or Plasma TVs, Cathode Ray Tubes only. There should be no (not any type) demagnetizing circuitry on that type of set, so I have no idea what you replaced/adjusted. I believe one of two things to be the problem. Either the LCD screen itself is bad (possibly it has been struck with something and that has broken electrical connections that cannot be repaired) so replacing the LCD panel may prove to the the fix. However, the circuitry that drives the LCD panel could be at fault, improperly driving an otherwise good LCD screen. That is a tough call. I would carefully inspect the screen up close looking for tiny cracks in the glass. This could be a pricey repair either way. Good luck on that one. Perhaps you should include some more history of the set. Did it fall or get knocked over, was recently moved, got wet... anything would be helpful. I know that children of a certain age are known to go up to a set and slap the screen. A friend has a rear projection Pioneer with that type of damage.

Screen blinked and then there was a dark band across the top of the screen

This sounds like one of the back lights have failed. This could be its power supply, and or the lamp itself.

Not all the screens can be service for back light failure. This is design dependent. Also, if you are going to change a back light and you can, it is best to replace all of them at the same time. If not the coloration of the screen will be different from one part to the other. With age the color of these lamps changes a little.

I would suggest with such an old set, I would get one of the newer LED/LCD sets. They are very far improved over the one that you have. Your set will be expensive to service, if it can be serviced.

Distorted Picture

Problem is likely main board (processes all signals) or even the power supply board is possible.

Considering brand parts may be hard or impossible to find.

There a multi colored lines across the entire screen how can i fix this? you can see the TV on.. behind these multi colored lines... very faintly.. please advise how this can be fixed.. chris trizano-...

Hello; Not much info given. Are the lines from top to bottom? , and does EVERY line go fully from top and bottom. If the lines don't go FULLY from top to bottom, you have a cracked LCD panel ( cost more than TV sold for ). If they all go fully from top to bottom, It can still be the LCD panel OR the LCD controller board ( much less expensive ) John

The TV has a thin horizontal line across the screen. Sometimes the line has color and sometimes the line is white. Everything else seems to be working (i.e. sound, channel changing, game hookups)....

you have a vertical output problem,take something insulated and prod around board and see if pix starts to flutter,then you could have a "cold-solder" joint,otherwise its more than likely a capacitor between the vert driver circuit and the vert output circuitry,
