Question about Dell Inspiron 700M Notebook

1 Answer

Screen goes out or shrinks to a mm line with rainbow color at top of screen

Dell has worked on it several times. After a small time period of leaving the laptop alone, the screen either goes out where I would have to restart it or the screen will shrink to one line of about a millimeter and will be at the top of the screen. Dell has replaced the screen and it has had no effect. It has been erased and reloaded several times.

What could be the issue.

I'm going to say that this is a problem with the video card. The video card controls the screen, and the screen wouldn't do this, so replacing the screen won't have any affect on the problem. As you have noticed. Have Dell replace the video card, and everything will work properly. I'm also going to say you will most likely have to be a bit forceful with Dell. Tell them you had it diagnosed by a tech, don't tell them it was on line. They know, or should know, that the screen won't cause this problem, and that the video card is the issue, but the video card is integrated into the motherboard, and motherboard replacement is the only viable solution. Sounds to me like they're trying to get out cheap.

Dell Inspiron D530 - Screen Malfunction - Rainbow colors?


Reseat the display cable (under the keyboard) and while you have the lcd hinge cover off, inspect the cable where is goes thru the hinge assembly for chafing and possible broken wires.

If reseating doesn't help, RUN DIAGS

You can't fix this by yourself. Your LCD screen is officially broken. If you have a service plan, you can generally get the phone exchanged for a nominal fee.

Green Screen - LG 42PX5D


hello, seems to be panel trouble, plasma and lcd main panels are not fixable, the color green isnt a good sign or it is a symptom of the panel being bad,
i know its a bad diagnosis but this is true with this color on a panel.
if it is a worth while set and you want to restore it theres few options one is replacement trough your waranty

the another is having the screen replaced by a service center this is to costly and rarely done by them they would advise you to get another set. at a retail price a screen replacement is as much or even more than the tv itself.

finally you may search online listings for a servicable tv same model and exchange the parts .
the third option is the best if your waranty is expired.

good luck hope this helps

happy holidays.

Parallel vertical lines through left side of Panasonic Plasma tv


This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

Monitor (Dell 1701FP) flickers, flashes and goes black


Just to check - when the screen is black- can you see any image- in its un-illuminated state. To do this look sideways along the screen not straight at it. I suspect this is an inverter problem. Whether or not this is repairable I know not- depending on your local repair facilities Perhaps DELL can suggest a local agent.
