The entire screen is flickering. You see 4 ghost images of people. Sometimes there are 6 to 8 inch wide vertical lines with zig zag edges on them. Auto convergence and manual convergence have been completed. Speakers do not work as well.

Take the television back to where you bought it and maybe they might repair it or swap it. It sounds like a defect in the TV.

BUT! Are you sure that its not just the aerial signal??

Toshiba L300 screen flickers and backlight


Maybe is the backlight power cable cut. Try with the laptop in power on mode oppening VERY SLOWLY the screen to see if at a certain potition it works fine. Open it all the way up sometimes to check it. If thre is a potition that it works, it's the cable as I mentioned.

The picture has ghost images, not lining up


This sounds like a convergence problem. Use the menu functions to reset your set's convergence. If this is not enough, you may need to replace the convergence board.

When turned on, the screen has waves in it across the top and flickers. It is unreadable. When the TV warms up it seems to be better but is starting to flicker or flash all the time now.


Hi,
Your Toshiba TV has hyperboard inside and there are few electrolytic capacitors (may be 10) that need to be replaced.
If you are comfortable with soldering parts in PCB then go ahead or ask help to any friend that knows electronics stuff repair.
Let me know further query.
Thanks.

"Flickering" screen


Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

This may be a convergence issue but it is difficult to determine with that description. Watch this video and see if it will help you determine if you have a convergence problem or possible something else.
