Laptop video chip and VGA service

Does your laptop display has permanent horizontal or vertical lines?

Is your laptop display dead even when connected to an external monitor?

For this kind of faults, you must bring your laptop to our specialised laptop service workshop so you can get an accurate diagnosis and cost. Most laptop VGA faults can be repaired or as a worst case scenario, the graphics chip can be replaced.

For a quick test, you can do the following: Connect your laptop to an external monitor and turn on your machine. If the problem occurs even to the external monitor, then your graphics chip is in a faulty condition and needs repairs or replacement. If the problem does not occur to the external monitor then you may experience a problem with the laptop screen or even with the laptop inverter or the laptop backlight.

If when you turn on the laptop you see the manufacturer’s logo (for example Acer, Sony Vaio, Toshiba, Dell, HP, IBM etc) but there are some horizontal or vertical lines displayed then the most common case is to have a problem with the laptop graphic chip.

Check the picture on the left to see an example on how a faulty laptop VGA adaptor signal is displayed when you turn on the laptop. The lines may be green, red or yellow in most cases.
