I suggest you connect the VGA cable from the computer to another monitor or a laptop, just to make sure that your monitor's back light is faulty. If it does show on the other monitor or laptop, then the back light is really faulty. And i suggest that you get a computer technician to open it up for you if you can not do it yourself. Or you can get a sharp-flat object and open the monitor starting from the bottom of the monitor working your way round to the top. You will notice finger-like structures that hold down the monitor covers together. Make sure you do not break any of those. When you open it, check on the circuit board where you connect the power cable. Check for any bulged or leaking capacitors. Capacitors have a job to hold down the power from the source long enough for your display. For faulty capacitors, the monitor will either remain black with the orange light blinking, or it will display for at least between 2 to 8 seconds and then goes black. Buy the same type of capacitors and replace the damaged ones. Please not the polarity as you replace the capacitors.. Good luck

Speakers on the VG700b View Sonic do not work. can you help


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 VIEWSONIC 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.

The monitor works when connected to my laptop but when I connect it to my desktop, I get a little message box that says Out Of Range?


Right Click on your desktop go to Properties (for xp) or Screen Resolution (win 7 and vista) lower the screen resolution. What the error means is that the resolution is too high and the monitor cant handle it.

Hello the speaker on my viewsonic vg700b are not working is there anyway to fix that?


Yes. It probably is, but you need to take the monitor to a specialized workshop to check the buzzers and all the speaker components. It is not a thing to do it alone at home. If you need further assistance or have further questions please leave a comment. Cheers

I have a viewsonic VG700b monitor. Everything is fine for the screen but the built in stereo speakers don't work. I'm pretty sure the wires are in the right place so can anybody help me????


First make sure that you are using the mini stereo male phome jacks on both ends, one end is connected to the Green audio line in of the monitor, the other end should be connected to the Green audio line out of the PC, also need to set the volume controls at the PC and the monitor, starting at 1/2 level. You can also verify that the monitor amplifier is wprking or not by feeding it with an MP3 player or some kind of audio source to see if you do get the sound OK.

Is this right for my broken view sonic VG700B ?? Size: 2.6mm x 342mm Part Number: 26342 Starting Voltage: 1500 Running Voltage: 650 Current: 5ma Wattage: 3.35 Intensity: 34,000 cdm2


Is this information from LCDPARTS.NET? I always remove the old lamp assembly and take an actual measurement of the lamp dimension before I place the order. The diameter is correct, but you should measure the length of the lamp, I know LCDPARTS.NET does give you some idea how to estimate the lamp size.
Are you sure that the lamp is bad, the common symptom of bad lamp is that it has pinkish light color wwen it first start up and slowly turning to normal white color light after warm up.
