I have compaq Evo N160.Laptop is just 1 year old & still in excellent condition.I got the vertical lines problem.My screen is full of colour lining from top to bottom as I start the laptop & it remains permanent.This lines changes colour at some stage when screen pic changes or when I run scan disk on HDD.Though the laptop works fine with external Vga monitor.
I would like to tell from when does this problem occurs......some days ago some ant(small insect) has entered my laptop through DSL cable(lan card).& very next day I got this problem
I have shown to 2 laptop tech person.One of the tech person diagonsis that inverter board is gone(which I knew now he was wrong).Second tech person says that either display ic or display cable is gone.Someone says that the whole display should be change.
I request to give right guidance to me...
Tks

Someone here mentioned twisting the display - which you can do on laptops - that might make the problem go away temporarily, but in my experience, it (the problem with the lines) will be here to stay. You can either replace the screen panel, or you can remove the screen panel and have it shipped to repair facilities that specialize in LCD repairs - both of which could entail considerable cost, effort, AND expertise.
A lot of folks will toss out the word "inverter" when there's an LCD problem, so let's get it straight once and for all: the inverter is just a power board that converts your laptop's DC power into high-voltage AC current, and this AC current is used to power the backlight tube (or tubes) of your LCD screen - to "light the screen up", if you will. The inverter is also responsible for the brightness adjustments in your LCD display. Hence... if your screen lights up and you can adjust the brightness on your screen, then the inverter is doing its job and you can rule it out completely.
Speaking of brightness in LCDs, some LCDs will give you a perfect image that's got a "pink" tint to it - that'll be, in the vast majority of the instances, due to a burnt-out backlight tube. It's just like a florescent tube that's on its last legs. You can either replace the LCD, or have the LCD delivered to a LCD repair facility that'll replace the dimming tube for you.
Now, if your computer's LCD is completely black (doesn't light up) but you can still hear the rest of it working, then it can be an inverter that's failed or, in the event that your computer has been impacted, it can also be a shattered backlight tube inside your LCD. Anyway, my point it: if the screen lights up, it ain't the inverter.
