It is normal for VIDEO 3 to be displayed in the upper left of the picture if there is no signal present at the INPUT 3 jacks. This is to let you know that although the picture is black and there is no sound, the TV is still on. If you have a good signal at INPUT 3 and the VIDEO 3 stays on the screen, take the Sony remote, point it at the TV and press the DISPLAY button until you see "DISPLAY OFF" on the screen. About 3 seconds later, the words should vanish.

Color bar on right side of screen


Primer:

An LCD screen cannot produce light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, or a series of LED's.

A CCFL is a Cold Cathode Fluorescent Lamp
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

{Average thickness is 2mm. That is a little larger than 1/16th of an Inch. Average length is a little shorter than the LCD screen is in height }

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

Scroll down, and look at the last 5 photos. General example of a CCFL backlight.


LED = Light Emitting Diode
The Gateway NV51B15U Notebook PC uses a series of LED's, for backlighting,

https://www.laptopscreen.com/English/model/Gateway/NV51B15U/

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.

Some of the older models that use LED's for Backlighting, did use a screen Inverter.
The newer LED backlit LCD screens, do not use a screen Inverter.

Average example of a screen Inverter,

http://www.amazon.com/Dell-Screen-Inverter-Latitude-Inspiron/dp/B003EXGHHU/ref=sr_1_1?ie=UTF8&qid=1343136763&sr=8-1&keywords=screen+inverter

The screen Inverter's location is down toward the bottom of the LCD screen, and behind the Display Bezel.
(The Display Bezel is the thin plastic frame, in front of the LCD screen)

If there is no screen Inverter, the only two things left that can be wrong, is the Video cable, and the LCD screen.
Upon opening the Display Assembly you will see if it uses a screen Inverter, or not.

Video Cable:
The video cable plugs into the motherboard, leads across the motherboard, then goes up under the left Hinge, and into the Display Assembly.
From there it connects to the back of the LCD screen.

Due to age, conditions, and just from normal opening, and closing of the laptop, the video cable can become pinched in the Hinge.

Just enough that it may damage the tiny wires inside the video cable; and/or pull on the video cable, and loosen the connection at the motherboard, and/or back of the LCD screen.

Your problem may just be a loose connection of the video cable at the motherboard, or back of the LCD screen.
How to check?

The laptop has to be partially disassembled, down to the Top Cover removed, in order to access the motherboard connection.
Plug in connection is found out to be tight? (Physically)

Then with the laptop still apart, re-connect the Media Cover, (Power On button), reinstall the Battery, and plug the AC adapter (Charger), back in. Turn the laptop on, and see if you have repaired the problem.

No?
Then the Display Assembly needs to be removed, and the other end of the video cable at the back of the LCD screen, needs to be checked to see if it is plugged in tight.

(ALWAYS check physically. See if you can plug the video cable in more tighter. The motherboard connector is fairly obvious if it is loose.
The connection at the back of the LCD screen isn't seen so readily.

For the connection of the video cable to the back of the LCD screen, to be loose enough not to work; all it takes is for the video cable connector to be the thickness of a human hair, away from the connector on the back of the LCD screen.

Both connections were tight?
Then look for obvious signs of damage, to the sheath of the video cable.
If there are outward visible signs of damage to the sheath, there is a good chance the tiny wires inside the video cable may be damaged.
(Stretched/Broken)

Best thing to do, is take the video cable down to a 'Mom and Pop' computer shop, and ask them to check it for continuity.
Video cable is bad? Replace.

Video cable checks out?
LCD screen is bad.

I do not have a link to give you for a Service Manual.
However IMHO I believe I can guide you without one.

To begin:

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Although you are not dealing directly with hardware components, (Parts), that may receive Static shock, I feel it is best if you buy, and wear an ESD wrist strap. Connect it's alligator clip to a good ground source.
(Electro Static Discharge)

The average cost is around $3 to $6. Here is but one example,

http://www.radioshack.com/product/index.jsp?productId=2103245

3) Use a multi-compartment container, for the various screws you will remove. Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise do NOT mix them up.

4) Make a personal record as you disassemble. Make notes, and drawings. Use a digital camera, or video camera, or at least a cell phone camera. (Use good lighting, make legible notes you can read later)

The Gateway NV53 series of Notebook PC's, is similar to the NV51B series. Not real close, but a good basic guide can be had by following a disassembly procedure for a NV53.

http://www.insidemylaptop.com/disassemble-gateway-nv-series-laptop-fix-power-jack/

Scroll down to Step 1. Look at the Bottom Cover. (Base Cover)
Different than yours. This is yours,

http://www.cdsparts.com/p-3211-new-gateway-nv50a-nv51b-nv51m-nv55c-lower-bottom-case.aspx

Unlike the pictorial guide you are not disassembling all the way. However you need to remove all Philips head screws from the Bottom Cover, and slide the DVD drive out. (Set aside)
There are 4 screws on the Right side, and 3 screws on the Left side.
The screw in the middle to the immediate left of the vertical vent, has to be removed. This is for removing the DVD drive.

Once the DVD drive is removed, look for 1 or 2 screws in the outer left edge. (Still looking at the bottom cover) There may, or may not be any. If there are they need to be removed, so you can remove the Top Cover. (Palm Rest Cover)

Look down in the Battery Compartment, now that the Battery is removed. Looks like 3 screws to remove in the middle.
(Middle line of Battery Compartment. One to the Left, one in the Middle, and one on the Right)
Towards the inside edge of the Battery Compartment, on your side, it looks like there may be 2 more screws.

These screws may hold the Media Button Board Cover, and Keyboard, to the laptop. These two items need to be removed, in order to remove the Top Cover.
[ Generally if there are screws to the Keyboard, it may have KB, or Keyboard, or a keyboard symbol, next to the screws ]
To the left/bottom is the Harddrive Bay. To the Right is the Memory Compartment.

Looking at the left side/top, in the Memory Compartment, it looks as though a screw may have to be removed. (White area towards top. One screw hole)
You need to also remove the Memory Compartment panel, Ram Memory modules, ('Stick'), and disconnect the Wireless Antenna wires from the Wireless Module. Make a mark on the terminals, and their corresponding antenna wires. The antenna wires need to be screwed back to the terminals they were on. (Step 4)

The Wireless Antenna wires STAY with the Display Assembly. The wireless antenna is in the Display Assembly. The antenna wires are threaded up through a cavity hole, in the laptop body. They go through Channels, and Latches. They MUST go back in the same routing as they were originally. Otherwise the antenna wires may be damaged, and the laptop will not go back together correctly.

Observe Step 9, and it's 3 photos carefully. The Media Button Board Cover, and Touchpad, use the same connector. USE CARE, and do NOT break the fragile connector/s. If you break one, you are looking at motherboard replacement.

Media Button Board Cover removed, Keyboard removed, the Display Assembly is next. I could be wrong, but looking at the Hinges for the NV51B15U, it looks like there are 2 screws EACH, on the BACK of the Hinge. (Back of laptop) Also 2 screws each on the INSIDE, as shown in the pictorial guide.
I would advise removing the back ones first, then two from the inside. One for each Hinge. When you go to remove the last 2 screws from the inside, make SURE you are holding onto the Display Assembly.

There are two connectors on the motherboard side, as shown in the link. I have looked at the video cable for the NV51B15U.
Thread the antenna wires up, and out, as directed. (NOTE the routing)
Look for screws in the metal shield, in the middle of the Top Cover.
Look carefully for any remaining screws on top, that may still hold the Top Cover in place.
The Top Cover outside edges have Tabs on them. Plastic tabs, formed out of the plastic of the Top Cover. The Bottom Cover has matching Latches. The Top Cover must be eased up, and off.
(Steps 19 and 20)

Disassembly of the Display Assembly to follow in a Comment.

How to get dvb chanels on my tv ?


If you're talking about the DVD then it will depend on what input you have it plugged in to. Follow the cable from your DVD player to your tv and read the name of the plug it is labled with. Hit TV/Video on your remote several times until it gets to that lable on the screen. example, If you have you DVD plugged in to Video 1, hit tv/video button on your remote or on your tv until the cursor highlights video 1. Movie should play.

No signal box


do you get any video on the LCD like a menu or something? if the screen has power and you are sure your computer is putting out a video signal it may be the inverter board on the LCD, this board feeds hi-voltage to the lamps that displays a screen and is a common problem with all LCD screens.

Hope this helps
thanks for your rating
