Alright, here is the solution!! I read this on another thread here and was so upset with my Toshiba’s black screen (I am a flight attendant and drag this laptop all over the world and back…I thought I broke it while going through security..where, of course they handle everything with tender loving care..lol)
Well I was just about to go online to buy a new laptop because my screen was black when I read a thread on this site and whoever figured this out WAS a genius…

This is what this person said to do…..

1) UNPLUG THE LAPTOP
2) REMOVE THE BATTERY
3) HOLD DOWN THE POWER BUTTON FOR ABOUT 30 SECONDS TO 2 MINUTES
4) THEN PUT THE BATTERY BACK IN
5) START IT UP..

It worked immediately…I nearly cried when it started up…We are in a recession right now and the last thing I needed was a laptop repair bill..

I see this issue all the time. Sometimes its the graphics chip. Sometimes its something as simple as the cable being a little loose.
I had a laptop the other day and the screen would work fine as ling as it wasn’t open very much. As soon as you opened it a little more the screen went into a rainbow of colours and lines.
When I opened it up, I found four wires broken and touching the metal LCD bracket!

Hello

I had to replace the lcd screen in my MSI PR210 laptop and having installed it I have what I can only describe as coloured lines flickering across the whole screen. they are very thin and seem to change colour. I can see the windows screen etc but the lines are really annoying!

I connected the laptop to a monitor and they don’t seem to be on that screen.

I have checked all the connections and they are all connected correctly – any ideas what could be the problem?

Thank you

Cliff Pooley

Hello.I am encountering problem nowadays on my laptop, Dell XPS 1330.Last week as i turned it on, the LCD becomes gray for too long,so i have to force shutdown it several times.After rebooting it and runs ok,in the middle of my activity,my monitors flicker tremendously then suddenly shut down it self.this scenario is not persistent because last night until now i don’t have that problem.I am still monitoring this problem.What do you think is the problem?I don’t remember dropping my laptop or hitting it hard since it is just safely sitting on my table. Pls advice.Thanks

Zac,

How can i tell if i need to replace my laptop’s lcd screen, or just the backlight, or the lcd inverter?

It’s hard because in most cases the inverter board and backlight lamp fail with very similar symptoms.

i have a gateway mx6650, and it has had pinkish tones for some time, but just 2 days ago, the screen started flickering wildly. it flickered for a while and then went dim (i could still barely see the dark image of the desktop.

You mentioned pinkish tones and I think it could be related to the backlight lamp failure.

Kyle,

However, at least once or twice a day the screen spazzes out in this vast array of colors, similar to the mentioned rainbow colored or monochromatic screens. Not sure why, though. Stops on its own.

You’ll have to test the laptop with an external monitor. If both internal and external screens fail the same way, there could be a problem with the video card.

If external works fine all the time and this problem appears only on the laptop LCD, it could be:
1. Failing LCD screen.
2. Defective LCD cable.

Brandon,

Now I still have to turn it on at the angle, only if I pas that angle,there are pink shapes that change according to what’s on the monitor. These shapes don’t appear on an external monitor.I have checked the video cable behind the LCD, nothing lose.

Could be bad LCD cable.
