Question about Envision G175 Monitor

2 Answers

My envision monitor, G175 professional series, will power up and run for about 3 seconds then shut off. If i shut the power off to the computer or the monitor and turn it back on, again it will run for about 3 seconds then shut off. I am not sure what the problem could be, any ideas?

I have a similar problem with my G175. I have found that by quickly hitting the menu three times and the decrease birghtness several times, the monitor will stay on for an extended time, although very dim. This may get you through for a while, but you ultimatelyt will likely need to replace the monitor, unless you feel equal to the challenge of being your own montior repair technician. I have not yet ried a different power supply between the wall and the monitor but do plan on that at some point. These can be subjet to the same capacitor issues the other poster mentioned. Good luck and let us know how you come out. Thanks!

It can be dying power supply due to bad DC filter caps or dying inverter circuits, worst case will be bad backlight assmblies.
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.

Attention no signal


Check this out with another PC to confirm the case before you can suspect the monitor. If so it can be due to failure of the signal processor within the monitor and so a hardware service is required for replacement of the IC.

When i turn on my monitor (Envision G22LWk) it will go blank about 1 second after I turn it on. What might be the problem?


You may have power supply/inverter board problem due to bad caps, or worst case will be bad lamp assembly, the one shown here has broken lamps, you can hear arcing sound if you listen real close.

Envision G175 monitor goes on then goes black


This could be one of three issues:
1) Monitor is bad
2) cable is bad
3) video card is bad.

Try to plug the monitor into another computer or laptop and see if your current setup still shows black. If it now works, I'm pretty sure that it's your video card, seeing the other 2 components work fine for another computer. If it still doesn't work, then replace the cable and try again with the other computer. If the new cable doesn't fix the issue, then I think that it's monitor that's simply gone bad.
If it's the video card, you're going to have to open up the PC and replace and reinstall a new one. (do a Google search for help on this, but here's one link: http://www.directron.com/howtovideo.html) The install is easy, but if you've never done it before I'd recommend help from your local computer geek (someone from work?) or a computer place such as Geek Squad (located in Best Buy).

If this has helped, please give me the appropriate thumbs up! Thanks, and good luck!

My envision 17" comes on for a few seconds and then it goes black...how do I solve this


Typical problem with LCD monitor, failed powers upply due to bad caps, inverter circuits, or bad lamp assemblies. You will need to open it up first and look for bad caps, then go on from there. Please see my pictures so you will know what to look for inside.

Envision Series / AOC 22 hdtv monitor


Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

Picture not clear and shuts off after about 2 seconds after being turned on


It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the Windows ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. If you can see the start button then it?s either the backlight tube or the electronics that controls it. This is repairable but I would not recommend the typical user try it unless they have tools and some experience with disassembly and handling of electronic components. It goes without saying that if you are unwilling to risk damaging the monitor you should take it to your local repair shop. You will spend about $50 more in labor but you save yourself guessing which parts are bad (a potential savings) and you will typically get a warranty of sorts. If you don?t see the start button I would next suggest you connect this monitor to another computer to see if the problem goes with the monitor or stays with the computer. Let us know what happens and if you need some more assistance.
