Green screen on Toshiba Satelite C855


Backlighting is accomplished by a series of LED's.

Light Emitting Diodes

As such no screen Inverter is used. This we can count out, then.

Display shows good on external monitor. Means graphics chipset is good.This we can count out, then.

All that leaves is Video Cable.

Provided of course, that it is not a defective LCD screen, or the wrong one was sent.

Video Cable connections are not tight at motherboard, and/or back of LCD screen.
Visual inspection alone, will NOT do.
Physically trying to plug in tighter, is required.

Connections proved to be tight, then the Video Cable needs to be removed, and a continuity test performed on it.

A multimeter is set to OHM's (1K), and every wire in the Video Cable is checked for continuity.

This test sends electricity through the wire, and if electricity flows through the wire, then the wire is deemed Good.

If electricity does NOT flow through that individual wire, then the wire is deemed broken.

An assistant is also used, to gently wiggle the cable.
If an intermittent reading is shown on the multimeter, then the wire is broken.

Replace Video Cable.

Suggest remove Video Cable, and take to the nearest computer repair shop; and have the resident tech check it.

If they do not know how, get out of there! You are talking to a parts changer, and not a technician.

OR,
Replace the Video Cable,

The display on my L675 S7048 is flickering badly. My whites turn pink, and my blues turn green. I see it when windows starts, even the Microsoft logo has tiny green dots all around it. When I connect an...


WHITE is a mixture of the three "primary" colours.
If one of the colours is not working, then WHITE turns PINK.

So, either your LCD display is malfunctioning,
or the "data" cable between the LCD and the motherboard is malfunctioning (not transmitting all 3 signals),
or the video-card embedded into the motherboard is malfunctioning (not sending all 3 signals).

This is nothing that you can fix by yourself; take your computer to a qualified technician, for trouble-shooting and repair.

Toshiba Satellite L35 screen color turned to pink.


If you have a LCD-screen, not an old-style CRT-screen, it is the data-cable, and its connections, that are not transmitting one of the 3 "primary" colours, e.g., mix red & blue & green to get white,
but mix only two of those colours, and you could get pink,
because the mixing is an "additive" process.

If you mix NONE of the 3 primary colours, you should get BLACK.
If you see GREEN, you're seeing ONE of the primary colours.

Toshiba Satellite M30 display problem


I decided to read this and I am not exactly 100 sure what the proplem is. I did want to offer a suggestion though. If you are having problems with both the screen and an external monitor, the problem may be with the graphics hardware. If you have a card, it may need to be replaced. If not, i'm very sorry. The motherboard may need to be replaced. Hope this helps.

TOSHIBA M30 DISPLAY PROBLEM


the inverter only control the back light this is the bright or dim in the lcd the blurry or funny images would be the lcd or lcd cable the only other thing is the 1 in 100 shot of it being a motherboard issue (video on the motherboard). the best thing to do is take the lcd out and try a lcd from another laptop maybe a friends laptop that uses alike lcd this does not have to be the matching size just matching lcd cable connection. be careful the cable should go on with ease no force if you have to force the cable on to the try out lcd then it will not work.
