Having problems with your Acer AL1912 19" LCD Monitor ?

Blank screeen I have a acer 19" Al1912. The power light flashes once every second. I can not get the monitor to do anything. I took it apart and the power supply board has a capacitor that the top has puff up a little bit but it is not leaking yet. When it is plugged in the capacitors get warm. I am not sure what the problem is exactly. Any help would be greatly appreciated.


Answers :

Been there, done that. The power LED cycling indicates that the switchmode PSU is shutting down and trying to restart over. Standard symptom, let me guess the bulging cap is on the top row. Replace it with a same value/voltage (1000uF/10V from memory) low ESR 105C type and you'll be back in business.
Sounds like the backlight bulb has burned out, this is a common issue with LCD screened laptops.

It's only a cuople months old, so I can get a new one, but even though THEIR device went bad, they want to charge me $1700 to restore data!!! Unbelievable!

No picture My vaio VGN FS740/w has no picture even when i turn it on. I have attempted hooking it up to an external monitor to test to see if it was the screen but there is still no picture.
