Viewsonic VX1962WM Monitor Repair
If you have a Viewsonic VX1962WM monitor that either has a blue power light and no picture (it may even be squealing a bit) then this should help get you back running. Below you will find a full walk thru on repairing your LCD monitor. The power supply board we will be repairing is a Darfon B092-XXX 27-D021625 Rev D2, this board is also used in the Acer P191W and X193W monitors. To do the repair you will need the following tools: Soldering iron, de-solder braid, Phillips screwdriver, flat blade screwdriver. You will also need the following electronic parts: Qty. (2) 220uf 25v capacitors, Qty. (1) 1000uf 10v capacitor and Qty.1 2200uf 25v capacitor. We sell a repair kit with all of the parts for $10.00
If you don’t want to do the repair yourself, use the service request link above. Most monitor repairs run $30-35 plus return shipping.
Now to get to the electronics we will need to separate the .front and back halves of the case. Use a small flat blade screwdriver inserted between the front and back halves. Start on the bottom surface in case you damage the surface. The best place to start is the opposite from the control panel so it does not get damaged. Once you get the separation started just work your way around all 4 sides. About every few inches there will be a plastic latch that will release.
Now flip the electronics assembly over as show. Remove the 4 screws as circled in the picture to the right. With the screws removed the power board will unplug from the driver card and can be fully separated from the rest of the parts.
his is the power supply assembly. The parts we will be replacing are circled in yellow. The parts are as follows:
C1 and C302 are 220uf 25v
C307 is 1000uf 10v
C305 is 2200uf 25v
When replacing the capacitors be sure to install them with the polarity stripe on the side going the same direction as the old one comes out. Usually the board will also have one side marked as positive +, the stripe side is the negative -.
