No display on laptop screen

please proceed adjusting the REED switch, see the diagram , clean it and tight the wire connectors very we.
2) tight the ribbon cable inside from display board or key pads.
3) tight connecttor wires from the display board vs lower board see the block
God bless you

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.

Nice to know. So what is the problem?




OH I'M JUST KIDDING!

See if the Display Cable has a loose connection.
The Display Cable is inside the Display Assembly, and comes out by one of the hinges, then plugs into the motherboard of the laptop.

The Display Assembly consists of the Top Cover, Bezel, LCD Screen assembly, Inverter, Display cable, and often the Wireless Antenna, and it's connecting cable.

Usual method is to remove all power to the laptop, AC adapter (Charger) and Battery.
Then remove the LED Display Cover, (Under the LCD screen, and in front of the Keyboard)
Then some have to have the Keyboard removed.

Check that connection.
Also remove the Bezel, (Frame going around the LCD screen on the inside), and check the LCD screen to Inverter connection.

If it all checks fine suspect the Inverter.

If I knew the laptop's manufacturer Name, and Model Number, I could give you more than the generic prattle above. (It's on the bottom of the laptop. Post in a Comment)

the only place you are going to find the exact repair manuels are at a dealership. Part stores manuels do not go that in depth on wiring diagrams.

It sounds as if your problem is in the ignition module mounted on the side of the distrubtor. Inside the distrubtor is what is called a relucter plate that rotates back and for to change the timing. There are several small wires underneather it, red and yellow Sometimes these wires will break and then you replace the reluctor plate.
Bill

im pretty sure these cars were already prewired for fog lights .there should be some plugs behind the bumper to fit them.if not get back i will explain how to wire them up.best of luck.

your system goes on auto protect mode. it can be repaired even without the shcematics if this is the only problem.

what particular module is he asking for?
