More likely to have power supply failure due to bad DC filter caps.

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed HP monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Hi the power led on the view sonic LCD is blinking and there is no display . can u please help me with that THANK U


It is blinking can be due to not getting the video signal or it is in safety shutdown mode due to short circuits or failed power supply due to bad caps or shorted out some where inside. Try it with another PC first.

You may be having either the power supply failing due to bad caps, or failed backlight inverter circuits due to short circuits, loose connection due to bad solder joints, or failed lamp assmblies. You will have to open it up and inspect the inside. Do you have proper tolls for electronics repair, isolation transformer for safety so you do not get killed by high voltages inside the monitor?

No power light; screen dead; no physical damage; computer crash with windowns updates; monitor stopped working too.


Try it on another PC first, if it still does not work then you will have to open it up. If you are going to DIY repair, then please read below and look at my albums so you will know what to look for inside.

It can be that it is not getting the signal from the PC, or it detects short circuits so it goes into shutdown and try to restart, or failed power supply due to bad caps. Try it on another PC and also check the VGA cable first. If it still does not work and you want to DIY repair, then please read below and look at alot of pictures so you will know what to look for inside.

Not likely to be sleeping but the failure in the power supply due to bad caps (bulging, leaking), very common in ALL LCD monitors. If you are going to DIY repair, please read below and look through my albums so you will know what to look for inside.

My view sonic monitor is turned on and then in a few minutes it turns off leaving me a black screen. what can i do to fix it?


Sounds like overheating of something inside. Open the monitor, get access to PCBs and observe for darkened areas especially over the power supply and inverter. Also that long working before shut down may tell about bad solder junction, also caused by constant local overheating - look for those with tiny cracks, especially over darkened areas on PCBs.
Most likely - that's the source of problem with your monitor. And, as far as you open the monitor, check for any popped electrolytic capacitor - never bad to replace them too.
