Horizonal line across middle of screen top half of picture perfect bottom half has small lines in picture hitachi hd S 69 plasma


I'm not sure if this model is the one that has resistors that go bad. You can actually purchase a pack of resistors in a kit. It will come with solder, the resistors and instructions. You can lay the tv out and take the circuit board out to find the blown components, and replace the bad ones. Takes about an hour start to finish and will cost around $65.00. It has been a few years since I did this, so I'm not sure on the price.

Horizontal thin line across the middle of the screen. Check the back-light inverter board, and CCFL lamps. Try these codes. If you wish to get more, try the following links. Both the sites linked have set-up code list & set-up procedure to many popular brand remote controls. Surf the sites with patience.

this happened to me aswell what you want to do is click the start menu on your pc when it is connected to your tv then go to control panel then click printers and other hardware then in that window on the left hand side it has a small window saying SEE ALSO then click display then it will come up with the window to customize the setting then change it to the required size of your tv. Also if you want to use the tv as your monitor do all of that then drag your icons across the computer screen and they will end up on the tv hope that helps

There is a white horizotal line across the screen of sansui standard TV with a picture showing within this line. The sound is OK. What causes the problem?


Your fault it known as "frame collapse" because the pictures frame has collapsed. It may be caused by a bad solder joint or a failed component. Not a problem for a TV engineer.

32 INCH ZENITH PICTURE IN PICTURE ABOUT 15 YEARS OLD.PICTURE DISAPPEARED AND ONLY HAVE A THIN WHITE LINE RUNNING ACROSS THE SCREEN.THE SOUND STILL WORKS FINE. IS IT WORTHWHILE GETTING IT REPAIRED ??


When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Please rate my help++++Thanks for using FRIXYA

I am getting a white screen (no picture) on a polaroid LCD


People any lcd tv with a white screen cause by the T-con board if you have some experiences you can check with a multimeter the (smd) fuse on the T-con board it is right in de middel on top in the back of the tv. you might have to move some of the boards to get to it. if the fuse is broken replace it with another smd fuse otherwise relace the t-con.
