My toshiba L35-S2161 the monitor only displays lines in colors, what to do to fix it


Since you diagnosed by using an external VGA monitor, you now know the fault lies in either the Video Cable, or the Display Assembly.

Your graphics chipset is good.
(Also known as GPU. Graphics Processing Unit )


A) Video Cable:
(Toshiba = LCD FL Cable )

See if the connections are good. Check the motherboard side connection of the Video Cable, AND the LCD screen side connection.

A loose connection can do this.

1) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L35/taking-apart-laptop-1.htm

2) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L35/remove-notebook-screen.htm

(On both links above you can click on the photos to enlarge )

Observe the sheath of the Video Cable for obvious signs of damage.
If the cable looks pinched, stretched, or torn, the tiny wires inside the cable may be damaged also.

Best method is to remove the Video Cable, and perform a continuity test of the wires inside the cable, with a multimeter.
(An economical unit can be purchased for around $8 to $12.
Analog or digital is fine )

B) Display Assembly:

Video Cable checks out OK;

1) Check the connections to the screen Inverter board.
Make sure they are tight. Make sure the Inverter board does not appear to be damaged.

2) Screen Inverter board:

Primer;
An LCD screen does not produce light. It needs an additional light source.

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

A Backlight is the additional light source.
A Backlight is usually a CCFL, or a series of LED lights.

The Toshiba Satellite L35-S2161 Notebook PC, uses a CCFL for a Backlight. (Uses 1 CCFL)

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

(Average size is 2mm Thick, and is close to the width of the LCD screen in question, Long )

A screen Inverter converts the power (Electricity) from the laptop, for the Backlight and LCD screen.

It is located behind the Display Mask, (Display Bezel), and mounted towards the bottom of the LCD screen.

http://www.zkarlo.com/selected-zkarlo-part/inverter-board-p2215.php

A bad screen Inverter usually causes a garbled display, or doesn't light the Backlight up.

To test a screen Inverter you need a sensitive multimeter, or use a spare Backlight bulb that is known to be good.

Bulb lights up the Inverter is good, the Backlight in the LCD screen assembly, is bad.

[ The LCD screen is composed of layers. These layers are held in place by a metal Screen Frame. {Resembles a picture frame }

The Screen Frame comes apart.

Screws are removed, and the Screen Frame comes apart in four pieces, (Four sides), or the Screen Frame comes apart in two pieces as an Upper half, and Lower half.

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L35/big/satellite-L35-screen-08.jpg

The Backlight bulb is taped to one side of the LCD screen layers, and is under that side of the Screen Frame.

The LCD screen layers MUST be kept aligned, as they were from the factory. For this reason alone, it is tedious for an experienced technician, and is usually not done at the consumer, or DIY level.

Hello
The RAM you re-installed is not installed properly, it need to install again properly, if the RAM is OK then it has to show display, if not the RAM gone bad and needs replacement.
Good Luck

How do I replace the keyboard?


next to the F1 key and the windows key (2nd upper key and second to last key) are two screws, usually under some covering. unscrew and lift top edge of the keyboard towards the trackpad to lay face down. Undo the wire ribbon by lifting the grey or brown tabs and remove ribbon and keyboard. Then install the new keyboard by inserting the ribbon on the place. Lock down with the tabs and put the plastic prongs (close to the space bar) into the laptop body first, and then close keyboard onto the final position. screw back in and thats all. nboulikas@gmail.com for any additional questions.

My wife has a toshiba satellite L35-S2151 laptop. When she went to turn it on, the orange battery light flashes 8 times and nothing else happens. Any clue as to what is going on?


Try turning on the device with the power connected if it turns on, keep the power plugged in for the entire day. See if you will have the same problem without the power supply. If it still occurs without the power supply, you may have a bad battery, you can verify if you can get swap battery from a similar laptop.

Toshiba Satellite L35 screen color turned to pink.


If you have a LCD-screen, not an old-style CRT-screen, it is the data-cable, and its connections, that are not transmitting one of the 3 "primary" colours, e.g., mix red & blue & green to get white,
but mix only two of those colours, and you could get pink,
because the mixing is an "additive" process.

If you mix NONE of the 3 primary colours, you should get BLACK.
If you see GREEN, you're seeing ONE of the primary colours.

LCD screen mostly dead


There are no lights to replace in an LCD. If the LCD is damaged in any way, it must be replaced. Sorry. Email me the model of your laptop. I may be able to find you a cheaper screen.
