Having problems with your Acer AL1714 17" LCD Monitor ?

LCD monitor display not working

\015 Hello hows it going.Coolguy008 told me to seek you out for assistance. My question is in regards to my LCD monitor. I have the Acer AL1714 17" model. When i turn my monitor on the green light appears and everything boots up fine. once i am at the log in screen it is so dark, very dim to see anything but if i you were to look an inch away from the screen, you could vaguely see what is being displayed. The image is only a little bit noticeable in a right degree of light. I would like to know what could be the problem to a very dim screen. It works fine but can it be the inverter, lamps or back light? thank you very much.\015

Answers :

The problem you have is with the backlight lamp, which is not turning on. When this happens only because lamp is faulty, Acer LCDs have a security switch that will not turn the screen on at all and will return a blinking light on power on led , as diagnostic feedback.
If you have a dim light it sometimes means that the bulb is still ok, but is not working. This often happens because of a faulty capacitor on inverter, which is powering the lamp.
Although the above symptoms are typical\015\012 of a faulty inverter, a faulty power supply, lamp, or A/D board can\015\012 produce the same symptoms.
It's also possible that an\015\012 inverter could have been damaged by a faulty lamp. If faulty lamp is not replaced before refitting the repaired inverter, in time, the inverter\015\012 will fail again.

Best thing to do is taking your lcd to a local TV repair or computer repair that works with lcd (ensure they work proficiently on lcds , some of them doesn't), to test if it is the lamp or a faulty component on board. If possible find a shop giving you some warranty time, as, if there is more than one problem the LCD can fail again in few days.
