Usually a completely white screen is an indication that there is no video signal being fed to the panel from the controller. For instance, if you take a working LCD monitor and just disconnect the video cable that goes to the LCD panel from the mainboard, it will turn on and off just fine, but it will light up bright white.

So, there seems to be an issue getting the video signal from your logic board to the panel. This can be caused by a bad cable, a loose connection, a bent and/or shorted pin (from plugging it in wrong), a bad logic controller chip, or a blown fuse/component on the LCD's circuit panel (PCB that runs across the top of the back of the LCD panel.)

Hope this help!

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.

SCREEN FLICKERS ALL THE TIME. HOW TO REPAIR?


Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;

White screen display


Hi,

Appreciate the direct "Ask Me".

Often, problems such as this is indicative of a failing capacitor in the 5V internal regulator section. Most capacitors uses a wet dielectric that dries out after some time due to heat buildup. In some instances, most of the capacitors would also fail ESR test. Additionally, you may want to check the external power supply if it is putting out the correct voltage as indicated in the reverse of the adapter box.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

This is a generic symptom that could happen to any LCD monitor.
The following is a generic answer applicable to most.

The most possible causes are bad capacitors or a bad semi-conductor.

Open the unit and check to see if any of the capacitors in the power supply or other boards look domed or vented on the top.

Replace any capacitors accordingly. Use the same value capacitors. Most often, 1000uF 16V or 25V, 470uF at 16 or 25V, 220uF at 16V or 25V.

If this doesn’t solve the problem, try checking the surface-mount transistors on the inverter board that run the lights. Some times these transistors go bad and can cause the power to cycle up and down. Check the area for any cracked or overheated ceramic or mylar capacitors.

Don’t forget to check for caps on the main board. Some times these boards are overly simple and only have a couple of caps, but other times they are teaming with them.
