I have horizontal lines in my compaq presario c508us notebook pc. i dont know how to fixed it.


First try connecting an external display to your computer using a cable and the VGA port and an appropriate cable (<$5)
If the display shows no problems it's the screen (most likely).
You can either have the screen replaced at a computer shop - this is likely to be in region of $100 ?) or buy a spare and do it yourself. However before you do that find out exactly what you need and how to do it. Search the internet. Some places are
the HP web page for this model, gives access to the service manual, http://support.hp.com/gb-en/product/Compaq-Presario-C500-Notebook-PC-series/3318986/model/3337791/product-info Also ask on the HP forum.

My compaq presario cq62-238dx felloff my hands, no scratches or damages are visible, when I first turned it on it worked as if nothing would have happenned, but later on the screen turned pink, the next...


I suggest you start diagnosing by using an external monitor, if available.
A VGA monitor.

(It can be a VGA monitor that looks like a small TV, {CRT}, or an LCD flat screen that has a VGA cable attached.
More information on VGA connectors,

http://en.wikipedia.org/wiki/VGA_connector

Laptop off, and VGA monitor off, connect the VGA cable of the monitor to the Left side of the laptop.
(Rear top port)

Turn the monitor on, and then the laptop.
Do you see a display on the external monitor? (VGA monitor)

No?
Press, and hold down on the Fn key (Function Key), and tap once on the F4 key.

A) If BOTH the external monitor screen, and the laptop screen have the same pinkish display, the problem is the graphics chip. (More on graphics chip in a moment)

B) If just the laptop screen is pinkish, and the external monitor graphics are okay, the problem is inside the laptop display.

1) Could be a loose connection of the Display Panel Cable.
{The Display Panel Cable attaches to the motherboard, and the LCD screen in the laptop display}

2) Could be a bad Display Panel Cable.
Possible damage to the Display Panel Cable is the the laptop display was open.

Look for signs of damage to the sheath of the Display Panel cable.
However the damage may not be apparent. The Display Panel Cable could have been stretched.
(Laptop display open when dropped)
The tiny wires inside the Display Panel Cable could have become damaged.

Testing requires that the Display Panel Cable be removed.
A multimeter is used to check continuity of each wire.

{Multimeter function knob is set to Ohms. 1K or 10K if these settings are available.
The Positive probe lead (Red) is touched to a wire at one end of the Display Panel Cable.
The Negative probe lead (Black) is touched to the other end of the wire.

Analog multimeter needle swings up, you have continuity. Don't worry about the Ohm reading at this point. As long as the needle moves.

No movement? Have a helper gently move the Display Panel Cable around.
See if there is continuity shown, or is intermittently shown.
Indicates a break in the wire.
Solution is to replace the Display Panel Cable.

Same with a digital multimeter. No reading, or intermittent reading indicates a broken wire.

Display Cable Kit - HP Part Number 595196-001
I have seen several listings on the internet.

3) Could be a bad LCD screen.

Check the connections.
Check the display panel cable
If this checks out okay suspect the LCD screen.

Compaq Presario laptop C300 - issues (orange light)


Sometimes when a PC gets stuck in hibernation mode, the only way to reset it is to remove the CMOS battery for 10 minutes and replacing it. It resembles a large watch battery and is usually located near the center of the motherboard.
