Samsung r505 manual

samsung mobile of that model wont play songs through btheasdset

http://www.nvidiageforcerepair.com/samsung-laptop-nvidia-repair.htm It is a video card malfunction

screen Inverter is going out.

Primer first if I may;

An LCD screen cannot produce light,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

(Click on the monitor icon)

It needs an additional light source. A Backlight is the additional light source.

A Backlight can be a CCFL, (Or more than one), or a series of LED's
(Light Emitting Diode)

The Samsung R505 series uses a single (1) CCFL,

http://www.screentekinc.com/Samsung_R_Series_NP-R505--15.4-inch--1280x800-wxga-laptop-lcd-screen.shtml

A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
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, or about the width of this capital letter -> O <-

Average length is almost as long, as the LCD screen is in height.

A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen and Backlight.
90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.

Primer over.

The plastic frame in front of the LCD screen is the Display Bezel.

The screen Inverter is located behind the Display Bezel, and mounted to the bottom of the Screen Frame.
The metal picture looking frame, which surrounds the LCD screen layers.
(3M link shows you an LCD screen is made up of layers)

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

B) Open the laptop.

There are 4 Screw Covers going across the Top, of the Display Bezel.
Two on each side of the Webcam.

There are 2 Screw Covers across the Bottom.
One in each corner.

These are gently pried off. I use a computer pick. I do not use a metal blade such as a box cutter, but leave it up to you.

The Screw Covers are made of synthetic rubber, or plastic.
They are held in place by a type of rubber cement.
I lift up at the bottom of the Screw Cover, where the base of it meets the Display Bezel. (Push in a little, lift up)

If you are careful you should be able to reuse them. If one doesn't stick anymore, apply a TINY dab of rubber cement with a toothpick tip.
I LIGHTLY stick them to the Display Bezel for safekeeping.

{Yes. They like to stick to the tool, your fingers, and passing airplanes(?)
Oh? You think I'm kidding? Sure. Just wait until you're taking one off, and a passing jet goes overhead } (lol!)

Remove the Philips head screws. (6)
No.1 Philips screwdriver, or equivalent Jewelers screwsdriver.

The Display Bezel has TABS going around the exterior perimeter, on the inside.
These Tabs snap into matching LATCHES on the Display Cover.
(Top cover with the laptop closed)

Just a basic guide, posted for the Display Bezel removal technique.
I would lay the Display Assembly back to an angle.

Then cut a thick piece of heavy construction paper, or equivalent; to just fit the inside edges of the Display Bezel.
This will help protect the LCD screen from your fingernails, when removing the bezel.

I would also start at the top right, or top left. Move towards either side, then go down side.
Use care as the sides are thinner. Also watch it on the bottom, because the Display Bezel may hang up on the Hinge Covers, when coming off.

It's made of space-age plastic, and is pretty tough stuff; but can be broken.

Once the Display Bezel has been removed, remove the single screw that holds the screen Inverter in place, bring screen Inverter out, and unplug cables. One coming in, one going out.

The connectors are different from each other on those cables, and only plug in one way.

Screen Inverter replaced, cables back in their Channels and Latches, snap the Display Bezel back in place, install screws, and Screw Covers.

I have this laptop (the PCG-632L). My laptop shiped with the "Vaio Notebook Quick Start" manual for the "PCG-R505 series". You could seach the Internet for this manual instead of the "PCG-632L" manual. The manual says "quick start," but it goes into slightly more detail than the average "quick start" manual (such as changing RAM).

check you monitor controls!! check the monitor's contrast control and brightness controls. these are the push buttons on the front of the monitor. or they may be knobs that you have to rotate either left or right to adjust the image on the screen. if it is an lcd monitor then please refer to the user's manual for that monitor.

please try here for manual:

Please leave rating if it helps.

probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver ic thus you could only see white display. A replacement of LCD panel is the best solution. best regards

with other SyncMasters pressing the "menu" button for at least 5 seconds helps ...
