You may to check your ram. 1 beep is usually a sign of ram/memory failure.

My laptop screen got wet now it has a dul screen and a dark area


I always start with seeing if when connecting an external monitor to the Laptops VGA output is the same or different to what you see when just via the Laptops screen. Reason is so that can narrow down to JUST Laptop screen or graphics chip, maybe even OR connection at cable either end, Motherboad or Screen.
Is the Laptop turning on alright i.e. no frying, I assume it has dried out from when it got wet. localised to screen only or possibly inside of Laptop....Lights up with power, fan spins hard drive spins, right? If so try an external monitor.

I have a Sony vaio PCG 5K7P, and it's not getting started...when I switch it on...only the fan works and the lights on wifi and the charger are working....no display on the screen and no processor


Laptop on, shine a flashlight at the LCD screen at various angles.
If you see a faint image the problem is the Backlight, or screen Inverter.

90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.
(IF the laptop uses a screen Inverter.
CCFL backlighting uses a screen Inverter.
LED backlighting may, or may Not use a screen Inverter)

No faint images?

See if the problem is the graphics chipset, or Video Cable, or inside the Display Assembly.

Graphics chipset:
Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.

This is an example of a VGA Cable, and VGA connector, (port),

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

Scroll down a little for cable example.
You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

Turn the monitor on. If a CRT type of monitor allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not;

There are at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down, and at the same time tap once on the F8 key. (The F8 key is the Display Toggle-Over key)
Still no display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F8 key.

No display on external monitor, suggests a problem with the graphics chipset.

Most of the time the graphics chipset itself isn't the problem.
It is due to inadequate cooling for the graphics chipset, and this causes a problem with the MOUNTING, of the graphics chipset TO motherboard. (BGA surface mount)

If this is found to be the problem I will go into more detail.
I don't believe that is your problem, but there is NO guessing here.
We are following a diagnostic flowchart.

Good graphics on the external VGA monitor, means there is a problem with the Video Cable, or inside the Display Assembly.

A) Video Cable connections can be loose.
Connection at motherboard side, or connection of small cable to screen Inverter from Video Cable, (IF it uses a screen Inverter), or connection at back of LCD screen.

A LOT of times a loose connection can cause what you are seeing.

Video Cable could be damaged. Wires inside stretched/broken.

Inside the Display Assembly:
Video Cable checks out after a continuity test, then the screen Inverter is next in the diagnosis. (IF a screen Inverter is used)

Screen Inverter proves to be good, the problem is the LCD screen.
NO screen Inverter is used, the problem is the LCD screen.

Sony drives me crazy with their model numbering system.
What is the other model number on the bottom of the laptop?
Start with a VGN?
Post back in a Comment.

Once I have a model number I can deal with, I will post back with step by step info, and additional manual information.
(Service Manual. Perhaps pictorial guides, and video/s)

Once i connect my gt5662 to a monitor nothing is on the screen, i know the monitor is in fine condition, i realize the graphics card it came with has 2 different slots, should i buy an adapter an hook the...


Did the computer boot to a monitor before? Is this a new monitor for this computer? The GT5662 came with an ATI Radeon HD2400 PCI-e video card. There is also an onboard VGA port on the back of the computer. The VGA port should be disabled. The ATI Radeon HD2400 PCI-e video card comes with two DVI connectors. With the back of the computer facing you, you would use the one on the right. You would have to have an DVI to VGA adapter to use them unless your monitor has a DVI connector also. Hope this helps. This is what the VGA and DVI connectors look like. _498.jpgmoz-screenshot.png

Installed the board, scren displays message no signal and stays black. no peeps or beeps. usb has power so do drives and signal leds


Check the cable between your monitor and computer. If this is a new install and you have added a graphics card, you will need to boot up once using the on-board VGA. Doing so will allow you to turn off the on-board VGA in the BIOS. Then you can shut down and move the monitor cable to the new graphics card and reboot.

Starting problem


check the processor fan is working or not. check its connector. Also check if there is any beep sound.
if processor fan is ok then disconnect all the cables, data and poewer cables. plug the power connector to motherboad only and listen if there is any beep sound there.
tell me after doing this, if problem doesnt solve.

No Signal


no signal mean that vga signal from cpu is not coming to it or may be this is a cable breakage relavant to signal from cpu.
2ndly, the matter of computer shuts down is out of sense because this kind of problem doent happens at this case.
check ur vga card, if it is seperately installed on motherboard.
the other thing that u can do is that;

unplug all the cables of data relavant to hdd, cd, dvd and anyothers and then switch on ur pc. hope it should work if anything is not wrong with the motherboad and ram, including vga

Reseing the bios shouldn't be a problem go ahead, or is there something I don't know? does it void the warranty? I don't think so.
