How do I disassemble a Vizio E3D470VX Smart TV, to clean out the dust inside the Screen


Hi Alonzo,
To clean the dust inside the screen, you will have to disassemble the LCD panel. It is a very risky job and there is every chance of damaging the LCD screen unless you have a real good experience of doing it. If you are not good at doing such jobs, please let some professional do it for you.

Acer 4745g black screen problem


So, if you can hear startup sound then motherboard, RAM and HDD is OK! Try to connect it with external monitor, if it's working on it, then problem in LCD, LCD light or LCD cable. If not working with external monitor then it is video card problem, if card is integrated then you need to reball or change at all south bridge on the motherboard, if video is as module card then just replace it with compatible one.
If LCD cable - disassemble laptop to get LCD cable and test each wire with any multimetr with sound beep and replace it if needed.
If LCD light - try to take LCD screen under good lamp then power on laptop and carefully look to dark screen if you see very dark Windows boot screen then you need to disassemble LCD housing, disassemble LCD, remove and replace LCD lamp with working one.
If all this cant help, then you need to replace LCD at all.

Screen on laptop is distorted halfway


A) Video Cable connections are loose:
Connection at the motherboard, and the connection at the back of the LCD screen, in the Display Assembly.

Both need to be checked.

[For Toshiba the Video Cable is termed LVDS Cable.

Low-Voltage Differential Signaling Cable. I will just keep referring to it as the Video Cable ]

B) Video Cable is damaged:
Observe the sheath at the motherboard side of the Video Cable?
Is there obvious signs of damage to the sheath of the cable?

If so, there may also be damage to the tiny, thin wires inside the sheath, of the Video Cable.

Due to the routing of the Video Cable under the left Hinge, the Video Cable may be pulled on. This can create a bad connection.

Due to the above also, the Video Cable's sheath may be damaged, and the wires inside.

A view of the Video Cable by itself,

http://www.batterystyle.com/toshiba-satellite-a205-s5880-cable-p-484063.html

If the Video Cable checks out to be OK, the next item is the screen Inverter.
To test a screen Inverter you need a sensitive multimeter. This usually means expensive. { Or use a known to be good, compatible screen Inverter } Just thought I would state that. Don't want you to completely disassemble your laptop, just to fix a Video Cable, or screen Inverter. {Or LCD screen)

Most consumers decide to just replace the screen Inverter because;
1) If the problem isn't the screen Inverter, it is the LCD screen.
(A LOT of people buy an LCD screen, when all they really needed was a screen Inverter)

An EXPENSIVE part.
(LCD screen? $150 to $400 approximately. Screen Inverter? Usually around $22 to $48 )

2) The ease of access to replace.

As stated, if the problem isn't the screen Inverter, then it is the LCD screen.


1) With ALL power removed, AC adapter (Charger), and Battery, remove the Keyboard Bezel, and the Keyboard.

This is the motherboard connection side.

Display Assembly removed with Video Cable.
Now remove the Display Bezel, and LCD screen assembly, to access the Video Cable connection to the back of the LCD screen.


{NOTE*
The screen Inverter is mounted at the bottom of the LCD screen, and behind the Display Bezel }

This shows the Video Cable, and it's connection at the motherboard side,

Scroll down, click on the photo in Step 9.
The Video Cable is the cable to the upper Left side. Has one Red arrow pointing to the left.
The photo in Step 10 shows the Video Cable disconnected from the motherboard.

(This is Page 2 of a disassembly guide. Pages 1 through 4 are available above, and below. Page1::Page2::Page3::Page4::Find another model,
in white.
Just thought I would state that. Don't want you to completely disassemble your laptop, just to fix a Video Cable, or screen Inverter, or LCD screen) )

2) LCD screen side:

All three links above will help you with checking the connections, or removing the cable to perform a continuity check. (Test)

Also with accessing the screen Inverter, and LCD screen.

My computer fell out of the car on its bottom closed. got it home plugged it in it started up great when it got to running the screen went dark. not sure what could be wrong


Seems that the LCD screen cable went loose at either its connection with the inverter board or the LCD screen itself. You need to disassemble the LCD screen panel & check the cable connections at both ends. I would also recommend to disassemble the whole laptop & check all connections. The fall might have caused any of the connections to become loose.

Hi, I have hp pavilion dv2500 laptop. I have display problem.pls help how to rectify it. If i connect exteranl CRT monitor Display is coming . Pls tell me how to disassemble the laptop.


You might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

In this service manual, you will find an illustration of how to disassemble the laptop & replace either the LCD cable or screen inverter board:
