Toshiba labtop the monitor has a rectangular line about 2 inches in length and flickling I need help to fix it

in a square or rectangular room take the length and width of the room and multiply however if you com up with inches you must reduce fractions for example 6" inches is .5 feet

I’m happy to help further over the phone at https://www.6ya.com/expert/jason_66344e9ad974c715

One dimension is the length lower case l, the other is the width w. The perimeter for this rectangle is P= 2*l+2*w=2*(l+w)=2*(7/8 +5/16)
=2*(14/16+5/16)= 2*(19/16)=19/8 inches.

Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.

Here is your formula:

VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)

If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.

Hi,
Please post screen image so to understand what kind of these signs are.
Thanks.

So whats the question ?

Some monitors have speakers built-in, some don't. The sound never travels through the 15pin d-type VGA connector. If the monitor has sound, there will be a small 1/8 inch stereo jack in the back or bottom of the monitor. Most all laptops have a headphone output jack (again 1/8 inch stereo) which is perfect for patching to external amplified speakers or to a monitor with speakers built-in. This patch cable can be purchased at Radio Shack, Best Buy, etc etc.

Unplug the tv wait a minute .Plug it in turn it on see if that fix the problem. these tv are computers and can go hay wire.just like a computer ,some times a reboot will fix things for a while.make sure you have a good clean source of power at the receptical and your not having power spikes or drops . Good Luck!

you have the vertical circuit "closed" you have to repair it checking
transistors and capacitors . if you can  it this work may be at low cost - few dollars

capacitor (either ceramic or electrolitic) that connect to vertical ic (TDA8173 or TDA 9302) is short or open. Check all capacitor in vertical range. tq

Check that the graphics drivers are ok and updated if there are updates as it's a little old know. May also be a screen fault, not worth repairing.
