Question about ViewSonic Computers & Internet

1 Answer

My viewsonic monitor has stopped working. When I boot my machine the start screen flashes and then the monitor goes blank. As the boot process continues, each new page flashes briefly then the screen goes blank. When I finally get to my desktop there is no screen. I have a dual monitor video card and 2 monitors. I have tried switching the monitors and aslo tried plugging the bad monitor into each output. The other monitor works fine on both outputs and both cables, so I am sure it is the monitor.

Viewsonic LCD?
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: My 20" widescreen viewsonic LCD

This is most likely a power supply failure, many many places offer a fixed repair price, for instance i have just seen a local PC shop offer monitor fixes for a flat $50.00. So look about for deals like that.
But usually when they break i recommend that a NEW unit be purchased as these days they are very very cheap 2nd hand and even new, and a new unit has a warranty too.
I get monitors all the time in my shop, and usually they are NOT economically repairable, often due to the fact that one cannot obtain parts for units much over a year or so old.
Also usually again, with experience and practical experience and according to the figures, a unit that faults, has 70% chance of faulting again after repaired within the next 6 months, as usually it has been stressed and something else will fail.
So my advice is to get a "Quote" for the repair from a good service center and go from there.

Got an acer aspire ax3812 tower is on but screen stays blank got any ideas


Change the internal Ram sticks. This can cause a "Hold" in the BIOS boot process, thereby stopping the machine from going to the Operating System. Hope this helps.

ViewSonic VX2235WM turns on than screen goes blank changed power cords cable cords viedo card cpu still same problem


The problem is most likely the monitor itself. Hook up an old monitor (usually someone has an old monitor laying around) if the computer works with another monitor you'll know for sure.
Look at your monitor using a flash light at an angle, if you can see a picture in the background you have a bad inverter.

You most likely have a capacitor that has changed value. When a capacitor goes bad it will work after it heats up. Sometimes a bad cap will have a bulging top or show signs of leakage. Sometimes can only be checked with a meter.

Monitor flashes image for split second then goes blank but green LED flashes as well


while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have
