No dispaly on Toshiba Tectra

EdStan · 30-11-2007, 10:59 AM

Hi all,

I recently aquired a Toshiba tectra which had been sat on and the screen had cracked! the screen was still working but with a big crack in it. the screen was then replaced however now it doesnt work at all. Ive checked all connections and they seem fine. when you turn the laptop on there is a quick flash of white light from the display and a little zapping sound and then nothing at all. if you connect a monitor up to it the display works however there is a hint of red in it!

Does this sound like an invertor problem or a backlight problem? or something else? if you alternate between the external display and the laptop display using the FN key then you just get the quick flash of light and the zapping sound and nothing else.

Any help is appreciated.

IT sounds like you either have the wrong display in the laptop (which is not hard to do as there are a ton of different setups) or something has been shorted out on teh laptop itself. The inverter just powers the backlight of a display, so if you can look really close at the screen and you see the display working then its the inverter, otherwie=se its something more. Make sure the part numbers match the part numbers from the old lcd screen before going much futher. Otherwise the next zapping sound you hear might be the screens last.
