Question about Acer Aspire 4551 Notebook
The switch on button light up but the screen is not starting up. help me please. thankyou.
Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

if you can see the start up screen in full color when it starts then the last update could have caused it,
But its more likely that the plug inside the back of the LCD has come loose and needs to be replugged back in,
READ CAREFULLY FIRST BEFORE STARTING
Removing the screens bezels will void warantee
In Saying that ,
Heres how I would do a screen replacement,
You will need a small philips screwdriver for this ...
Remove the power and battery
To Remove the bezel from the front of the screen
There should be 4 or 6 screws holding the cover on,
Screws may be covered by rubber buttons,
then remove the screws holding the LCD to the hinges' frame.
Tilt forward your LCD and lie screen on your keyboard
LCD panels have a row of IC chips at the top that produce the images on your LCD so do not touch or flex this area because it may produce lines on the LCD or kill it completely.
botom of screen is inverter power and plug to screen
top rear of LCD is video feed from motherboard,
(above that are those important IC Chips-
DONT TOUCH THE CHIPS)
LCD wiil have tape fastening plug to the socket,
Remove tape and this will expose the plug.
Un plug from screens socket,
Reseat plug back into socket,
Put Tape back on to stop any unwanted movements,
Next step is to power up the LCD to test.
Rest LCD in back of lid and lie lid on table with base at 90 degrees for access to plug in AC power.
do not use battery for this test.
Turn ON power,
If it starts up, then you have a running machine again,
Shut down , unplug power and reassemble,
If LCD does not start then you need to replace the LCD panel and thats about all you can do,
Hope this helps.......
