Removing back panel of a viewsonic monitor


There are almost always plastic clips along with the screws. I'd recommend buying a plastic pry bar. You can google for them online and they cost $1 or so.

How do I remove the cover from the Viewsonic VA1912wb 19" monitor? I've removed the stand and the two hidden screws behind it but it won't come apart. Please advice, Anders


I was equally frustrated by this, but eventually figured it out. There are two finger-sized slots on the bottom of the panel covering the monitor's connections. Push them in (towards the top of the monitor) and lift the cover away from the back of the monitor.

Good luck,
-Brad

Remove back panel


You have to remove the base at the bottom (4 screws), all the screws on the back, then use a thin flat-head screwdriver or other thin brybar and work around the back panel unlatching the snaps that are in place.

After the back cover is off, the metal cover over the board and power supply can be removed by removing the screws around the outside lip of the cover, along with the screws on the bottom and right hand lip of the raised area in the back.

Hope this helps.

Vx800 flickers when cold


I have repaired several Viewsonic VX800 monitors. The symptoms include a power light that flickers or flashed on and off or a screen that flashes on briefly or stays off. The problem is bad electrolytic capacitors on the power supply board. These bad capacitors do not look bad and do not swell but they do develop a high ESR (Equivalent Series Resistance). You need a ESR meter to check them. But if you have these problems, you should assume the capacitors are bad and just go ahead and replace them.
First you must open the monitor and gain access to the power supply board.
1. Remove the stand: It is held with 6 screws on the back. Also on the back are 2 black screws that must also be removed.
2. Remove the button bar from the front, bottom: It is pried off. This will expose the 2 screws holding the front plastic bezel.
3. Remove the silver plastic bezel from the front: First remove the 2 screws holding it, then you can pry the rest off. This will expose the 2 screws holding the screen to the plastic back.
4. Remove the screen and electronics from the plastic back: Remove the 2 screws holding it. The 2 speakers are glued to the plastic case. Cut the glue with a knife. The screen and electronics and speakers should lift out of the plastic back.
5. Remove the metal cover to expose the electronics: There are 2 screws holding the VGA connector and 2 screws holding the DMI connector. There are 9 screws holding the cover. These must all be removed. There is a black plastic sheet glued to the lower edge of the cover. It must be lifted. The cover should now come off.
6. Replace the bad capacitors. The power supply and signal processor are on the same board. It is marked VG800-2. The bad capacitors are surfaced mounted 100UF 25V. The bad capacitors are CM16, CM17, CM2 and CM165. The two most critical are CM16 and CM17, but they all read high ESR, so I just replace them all as long as I have them exposed.
Reassemble in reverse order.

Disassembly of case


This is for a Viewsonic VX900. The bottom bezel with the button unclips.Unplug the connector, and put aside. ( Dont pull on the wires) Then there are two screws that are removed, and the grey frame around the monitor comes off next. Then remove the 4 bottom screws, and the two top tiny screws and the LCD comes away from the back. Remove the shielding, and replace your components. Good Luck !!
