I'd check in the control panel under sounds and see what the system thinks the output device is. Probably not the speakers. If not, change the output to your computer speakers.

Right click on desktop, choose properties from the pop up menu, in display properties choose the settings tab and set the resolution using the slider to 1920×1080 which is your monitors optimum resolution.

Just don't pay more for a repair than a new one would cost.

There are 2 boards/parts involved with this problem

a) The power supply board:

The main problem are 4 bad/defective capacitors
1. 22uf 400v
2. 47uf 50v
3. 1uf 100v
4. 22uf 35v

You can find them near the PWM IC controller (U601). Replaced all these capacitors regardless they look good. I pulled them out off the board and tested them with my Blue ESR and capacitor tester and found 3 were defective.

Next, you need at least 97% Isoprophyl alcohol and toothbrush to clean the soldering paste. Due to overheating on the primary section / HOT section the soldering leads tend to produce brownish paste which is causing the component parts to SHORT. Concentrate at the back of the board, especially at the U102 (16-pin IC) and Q202 transistor by scrubbing them carefully. I used magnifier to make sure the legs are clean and shiny. Clean the rest of the back and some part on top of the board. Let it dry for 2 hours at least. I did 2 times this cleaning to complete the process.

b) The Main Board

The main board has 2 bad capacitors at C124 and C126. I replaced them and cleaned also the board with alcohol.

That's it. Good Luck.

might want to unplug everything and let it sit for a half hour and try to plug everything back in. Try a different outlet maybe.

In this model the capactors hardly ever dome or vent. Usually you will see the top of the labeling on the capacitor has shrunk a little from it's normal size. If the monitor still has any kind of power (which it does from your comment) you or someone you know can replace those capacitors on the output side of the supply. If you're lucky this will solve your problem. If not, you can always try replacing the four brown electrolytic capacitors on the inverter board (the long board on the left when viewing the monitor from the back). There is a chance this could be caused by the inverter board or even a bad backlight, however I would bet it's the power board. If you don't want to replace the capacitors or replacing them didn't solve the problem, contact Viewsonic at viewsonic.com and get the price of a new power board. They are pretty easy to replace.

You have a unit with a failing power supply. When the parts called capacitors in the power supply start to fail they can't hold the charge like they should and it take a while for them to build up the charge and allow the power supply to turn on. Once they have a charge built up they work fine until the unit i turned off for a while and their charge drains then it starts over again. Here is a link to a parts kit that you can use to rebuild the power supply board and return the monitor to a working condition.

I hope this helps, if so please rate my solution.

They may have High ESR, you need cap meter that can measure ESR (Equivalent Series Resistance).

Look for bad caps as you can see in my VIEWSONIC VX series albums.
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.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Please leave rating if it helps.

Hi,
Welcome to Fixya. The problem happens to me several days ago. It seems that there is a component on the motherboard that has been burnt. If you're familiar with electronics or electronic parts of the lcd then you can just replace the burnt component like the capacitor, transistor or like. If not better to bring it to a service center to have it fixed. Better not to use it because it can more issue on the monitor because other components can get burnt as well.
Thanks

Hi, According to your problem, Check the adjust switches and readjust the monitor first. You have to repair the PCB of the monitor. Better if you can replace the PCB of the monitor.

The power supply on lcd and other flat screen type monitors utilize a group of capacitors as a static pulse for the screen to energize..my bet is that one or more of those have failed...it's actually a common problem with flat screens. Most of them, those that won't power up anyways, have this exact same problem. If it's not that, then your power supply is burnt out, and if that's the case it may be cheaper to get a new monitor instead of trying to fix the old one.

ViewSonic... | Answered on Sep 01, 2011


just google search the model number of the power supply.
I would go to ebay and look for it there.

The power switch is a TACTILE momentary switch type, it does not latch. You may ahve bad power supply due to bad caps as you can see in my Viewsonic VX series albums.

Good day,


I think is impossible to to add a remote control if your tv has no IR remote sensor in it. It is only possible to hook up a remote control if you have a PC hook in your tv, by installing PC remote control and TV Tuner that is available in Computer Shops.
