Sounds like the power supply regulator is shorted or the high voltage protection circuirty is acitivated. If you know electonics you can identify the power regulator by a large heat sink. There may be more than one large heat sink. So get the numbers/letters off of the part and google it to determine if it is a regulator. With an ohm/volt meter you can check the regulator, it's output should be near approx. 130 volts ac. If the fuse is being burned open you need to locate the short. If you don't know electronics please save you own life and stay out of the monitor. The red lead that goes to the CRT can have as much as 30,000 volts and the CRT stays charged even when the power plug is removed.

My Aspire L100 wont start up. my monitor says Power Saving Mode. what does this mean to me? and what can I do to resolve this issue

Hi there, sorry to hear you are having problems, Power saving mode shows that the monitor is not getting any signal from the PC. If the PC fans start whirriing and you see lights then it is either the monitor has failed or your graphics card in the PC. To eliminate, connect the PC to another montitor and check to see if you see images. If you do, then your monitor has failed. If you do not then you need to buy a new graphics card and install it in one of the spare slots on the motherboard.
If you do not hear any fans whirring or see lights at the front then it is your 1. Power supply failed 2. Motherboard failed 3. Processor has overheated and failed 4. RAM memory has failed Please let me know more information so we can narrow it down.
Many thanks

Moniter no display but power ok

as a computer technician by trade i will the obvious and move through to the complicated procedures and if after this you have no luck it is dead
first is there a video signal coming out of the computer
second is to video cable (vga) still good
third do you hear a crackle or obsesive humming while in operation(if yes disguard imediately)
lastly does the screen change shade when turned on (if yes you have a video problem)
and remember if it did not meet these criteria then disguard imediately as dead crt monitors can be very dangerous or harmfull should it blow out.

hope this helps and good luck

Even if i switch on my computer with moniter it doesnt show anything on moniter screen it remains black

Hello. With the computer and monitor OFF, disconnect the signal cable from the video card on your system. Next, turn on the monitor. There should be a bright green box with a pink outline of a video connector inside showing. If there isn't, and the monitor is definitely powered up, then there is an internal problem. If there IS a little green box, etc., the video card in your system is suspect.
  • 1) When turning on the monitor, do you hear the sound of the high voltage initiating?(i.e. you should hear some type of electronic noise like a vibration or crackling of static on the picture tube)
  • 2) If you do hear that high voltage kicking in, it may very well mean that the picture tube is dead and getting a replacement monitor is in your future.
  • 3) If you don't hear the high voltage, quite possibly the transformer that produces it(called a flyback transformer) is defective.
Due to the vast array of inexpensive monitors available, you probably should consider getting a new unit--the cost of a new display will rival the cost of the repair--and you get a fresh warranty to boot. If the picture tube is gone, there's no choice.---Rick
