30 bad VP930B's may have green LED for an instant that's it. No display either.
Yes this is a very common problem on the VP930b. The fault is with the
crappy CapXon capacitors (worst in the industry). As mentioned above,
replace the 220uF@25V and 1000uF@16V capacitors. The other two never go
bad. Make sure you replace the four above even if they look good. I
would recommend using 35V and 25V respectively.
Note, if your monitor serial number starts with Q8H you may have a bad
IC on the main board. Q8 often goes bad a few months after the
capacitors do. If they are warranty they will have to be sent to
Viewsonic or a local authorized service center.
If not warranty, you can solder a wire from the 3 pins on the left side
of the IC to the four pins on the right side. One pin on the left side
is the on/off pin for this IC and should be left alone. This will
bypass the IC allowing +5V to the LCD all the time. However, if the
monitor ever shows scrambled graphics after turning it on then turn it
off using the main power switch in the back and turn it back on, it
should be fine.

Hi My VP930b has ared
A red/pink streaks or tint is a indication that the CCFL lamp about to fail. The CCFL lamp is a mini fluro tube. The wires on existing CCFL lamp requires unsoldering and the new CCFL lamp soldered back on to these wires.
Replacement CCFL lamps for your model monitor are available from this WEB site.www.lcdparts.net

My monitor dont come on,
If your ViewSonic LCD monitor has stopped working with a
blinking green power button, It typically means that there is one or more failed capacitors in the monitor. It would be best to send the monitor in to Viewsonic for service or to purchase a new monitor.

Hi i have this monitor it was running as second
This is a very common problem with LCD monitors after a few years of use and if you can solder you should be able to repair the monitor yourself.
The problem is caused by blown capacitors on the power board. Go to our
web site at : www.ccl-la.com/badcaps.htm
We have pictures of what to look for. Open your monitor and look at the
power supply board for any blown capacitors, replace all that you find.
The replacement parts can be ordered from several places on the
internet or we can supply them for you. The replacement parts will need
to be high temp and will be marked 105c. The values you need to get
will be marked on the sides of the ones you take out but will be
something like 220uf, 470uf, or 1000uf etc. and then a voltage rating.
When you install the new ones be sure to insert them with the polarity
stripe going the same direction as the old ones come out. If you don't
want to do the repair yourself we do offer a repair service for $35
plus return shipping. If you have any questions just let us know
I hope this helps if so please rate our solution.
