Viewsonic Vx2235wm LCD Monitor NoPower



It is recommended that you watch video on maintenance
training.

Viewsonic Vx2235wm 


Viewsonic LCD Monitor NoPower that means the monitor unable to turn on. We are going to test by another power cable and socket to make sure they are not faulty. 

Better we use soft cloths to covering the table to avoid the happening crash on LCD Screen or front cover. Put the monitor face down on the table and unscrew all screw from back cover then take off the stand and the back cover. 

For access to Boards needs to take off four lamps connectors and unscrew the eight screw the aluminium cover. We can see two boards that the right side is MainBoard and the left side is PowerBord that they connected with nine pins voltages.

And in this video we can see  two Flat cables that connected between the mainboard's output and  LVDS Screen input. Usually, mainboards have one output to LVDS( one Flat cable).

After about one year of being used any LCD monitor needs maintenance. One of the power board duties is provided +5V.

For this, you need a Rectifier Diode and three Filter Capacitor because you will usually see some bulged capacitors. 

We have to exchange the capacitors in the troubleshooting progress. If you can't find the same capacity of capacitors it is preferable to replace with a higher capacity of Capacitor.

I hope this post was helpful and that I helped solve your problem with the Viewsonic LCD Monitor.  Please share this with your friends on social media.
