My toshiba satellite laptop screen goes black every time I open it passed 90 degrees what should I do

As in this model?

The Display Assembly is laid back to a point, that you can access the two bottom screws. Isn't a direct 90 degree position with the screwdriver. More like 60 degrees.

No?

Then the Top Cover (Palm Rest Cover) has to be removed, in order to access.

Don't forget to remove ALL power. AC adapter and Battery.

It should be a Problem of a loose conection.
if you feel you are good to take it apart there are a lot of tutorials on the web in how to take it apart and reattach the flex cable. (maybe even change it)
otherwise take it to a laptop specialist

you have a break in the cable between the display and the motherboard. It will have to be replaced. Samsungs did this all the time but not heard of tosh doing it. There's always a first time. I would check the cable at both ends first before replacing it.

The wire that connects the lid with the motherboard might be damaged, but not completely damaged as you use your screen normally, so i recommend that you check this connection.

Reset the video card, and if that doesn't work it sounds like the card is dying. How old is the card?

according to the downloadable user guide at toshiba support page , it appears , FUNCTION / SPACEBAR keys switches the landscape / Portrait modes . have you tryed that . good luck .

Sounds like the ribbon cable connected to the display is loose, I would send in for repair, shoun't cost much.

Hi, This is definitely a loose connection problem.
Does the screen go completely black or just a part ?
If its just a part, LCD is defective. You may have to change the whole LCD screen. You can get one for ~180$ from ebay
If the whole is turning off, I guess the power cable might be little loose.
You can open the LCD panel and check if you know what you are doing.
Else take it to a normal technician and ask him to open the LCD panel and see it.

You can flip the screen around by holding down

CTRL + ALT AND ARROW KEY

CTRL + ALT + right
CTRL + ALT + left
CTRL + ALT + up
CTRL + ALT + down

with these keys you can flip the screen around as you want. Noting serious.
