Question about ViewSonic VP140 Monitor
The screen would blink on and off, but a good slap to the top of the unit would stop it for a while. The screen finally stopped working all together. Can the screen be fixed?

This is a Common problem MOST if NOT ALL, problems like this with this type of fault it is invairably a problem with the Power Supply, in the PSU Electrolytic capacitors dry out and often cause this type of exact problem... It is a relitively simple fix, by replacing the caps with new ones... Any good shop should be able to fix for a modest fee.. OR if ya know anyone handy with a soldering iron maybe they could do it for you there are generally about 4 - 6 to replace... in the PS section, just do them all to be safe

Its a problem with the inverter. check the 4 transistors, C5707 near the connectors for the backlight. If none are defective, look for the PF751 FUSE. It sure to be busted.You can replace that with another 3A fuse. Remember, you should only replace the fuse if you are certain there are no busted transistors in the inverter board. Otherwise, you now have a refurbished Benq Monitor

A blinking blue light indiactes that your power-inverter board is not
putting out what it should. It needs an overhaul which may be a simple
as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

Your monitor has a bad power supply board. This happens often on LCD monitors because of the heat buildup in them. If you can solder them go to our web site at:
www.ccl-la.com/badcaps.htm We have a step by step dis-assembly and repair guide for your monitor. There are several versions of the E173FP some end in b , f, or c so be sure to check your monitor.
I hope this helps, if so please rate my solution.

Try connecting to a different computer to insure it isnt the video board of the PC. If same results it is in the monitor. What I've seen a lot lately is capacitor problems especially on the power board. if you are willing to open the monitor then you should see two boards, one for power and backlight AC power (should have 4 plugs into it all the same). Look at the can shaped parts that have stamped in marks on top, usually looks like a K. If they are all perfectly flat then it's something else, maybe the other board that handles the video. If they are humped up (swollen on top) or have a residue (leaking) then you will need the capacitors replaced with the same microfarard (uF) value and voltage value positioned the same polarity as the old (dashes on one side means negative side). If it has 25V capacitors you can use 35V but not 16V. You can go up one series of voltage but not down. Capacitance in uF needs to be the same.
