    Viewsonic VP201B Monitor Problem

    Hello Badcaps people....My name is Greg and I am Clueless in Indianapolis. I'll be honest and say that I am an old man and NOT so tech savvy. I have been having a problem lately with my monitor and have been trying to do some internet research about possible problems. I came across this website which seems to have some very helpful people who might be able to shed some light in my direction. It would be much appreciated.

    I have a Viewsonic VP201B which just started acting up. The problem is that it is shutting itself down randomly after awhile. It can happen anywhere from 10 minutes to 2 hours. When this happens, the display goes black and the power led goes OFF. If I unplug the monitor and let it set for 30 seconds and plug it back in, I am good to go for another interval. I have tried to find out the problem by searching the internet and trying to solve the problem without asking stupid questions to knowledgeable people but with no luck. While trying to research this problem and have been able to locate many, many posts (here and elsewhere) about a problem with capacitors where the display goes black and the power led either blinks green, stays on and is green or is amber. I either am not using the right pattern of search words or just am missing problems with my particular situation for some reason.

    Things I have done include:

    01. Changing out video cables.
    02. Using the monitor with another computer.
    03. Using a different power cord.
    04. Bypassing the outlet strip and connecting directly to the wall outlet.

    All of these have failed to remedy the situation and I have yet to open up the monitor yet as I was hoping for some opinions about possible causes. Thanks for any thoughts.

    That model is prone to power failures due to bloated caps on the PSU. You must open the unit and change the 2 or three (I can't remember well, but I think they're three) 1000uf 25v caps on the PSU and your problem will almost for sure be gone. Post the cap data and PlainBill, PCBONEZ, Willawake or one of our other senior members will point you on the right direction.

          Re: Viewsonic VP201B Monitor Problem

          Just repaired a power supply for one of these units (VP201/VP211b).
          The C11 (22uf 50v Nichicon PW(M)) was bad and it caused the PSU to deliver just 3.80~4.12v instead of 18v.
          Also replaced main filter cap (the big fat guy) because one leg was loose.
          Now the PSU bring the logic board & company to a nice shinning green led.

            Hello Clueless,

            The problem you're having is quite common with VP201b's as they age. The problem is with the INVERTER board. They are not available anymore for swap out from ViewSonic since their source quite making them, however, I have a company that does repairs to them quite quickly and cheaply. I run 8 of these monitors (5 on a MacPro, 2 on a PC and 1 on a MacMini) for years now and I do all of my own board replacements. I keep a supply of extra logic boards and inverters on hand. I've never had a power supply go out in over 10+ years on any of these units, but many, many logic and inverter boards... especially the inverter boards. Removing the board is quite simple. You can easily figure it out when you open the case. Remove the 4 screws then "pop" the case open by working a flat screwdriver to separate the case at one point and working it around. Don't worry, you won't break the case.

            The contact name for these inverter (and all inverter boards) is:

            I don't monitor this site. I was just surfing for some junked 201b's. I need some LCD displays since a few of my 8 units are starting to "leak".

              Not to sound rude or anything, I really don't intend such, but people usually come here asking how to recap boards, not where to buy repaired boards. ;p

                I feel proud that in just a year I have fixed 5 power supplies more than you in your 10+ years of experience .....
                And if you can read ( I bet you can, after 10+ years of fixing logic boards) you MUST know that clueless wrote "...the display goes black and the power led goes OFF...".
                Also, you should be aware that the bulging caps on VP201 & VP211 Viewsonics is a known problem.
                And if you can read (now I am PRETTY SURE YOU CAN) you should know that you can't advertise in the forum.

                  Fixed my problem, thanks. Old cap measure 4uf instead of 22uf.

                    Problem with monitor DS-D5022QE-B
                    by Askic
                    Hello to all,

                    I have a problem with monitor that is delivered together with CCTV system.
                    The monitor appears to be completely dead, there is no LED power diode and it doesn't react to pressed power button.

                    I have disconnect display and check many components on the power supply part of the board. There is no anything obvious and monitor is about 3 years old. There are no bulged caps. When measuring voltages on the output connector to VGA board I can measure stable 14.5 V on 12V pins and stable 5.07V on 5V pins. So I assumed that this part of the board is OK....

                    I have an intermittent display problem with my monitor, when I plug in the HDMI cable to my (or any) laptop, you see the connection screen shrink on the laptop as it usually would before displaying on the monitor but 95% of the time the monitor display stays black.

                    Before it cut out all together, tapping the monitor control button a fair few times would make the screen display, and everything work fine.

                    But now it never does it. Not sure what's going on, hoping someone can help. I'm capable of stripping the thing down and soldering in new parts if needed, or programming...

                    Recently, I got the captioned monitor and the owner said it could not be turned on. I open it up and found that one of the SMT capacitors seemed to be bad. I replaced it as well as the other one. The monitor still could not be turned on.

                    I found the power indicator is on. When I shine a flashlight on the screen, I can see the image. Therefore, I think it is with backlight problem. I took out the led strip....

                    I'm new to this awesome forum, and have been reading like mad, but have not seen the answer to my challenge.

                    We bought this Panasonic plasma monitor 16 years ago and it has never been serviced, so all parts are original, and the unit has never malfunctioned -- until about a month ago. The system fails to power on. At first (a month ago) this happened rarely. We learned to unplug for a few minutes to drain the caps, then re-plug, and the monitor would start normally. Now, we plug-in, turn on the main power switch, and the...
