My Envision 7100 Stop Working

My Envision 7100 stopped working on any monitor. Even power connects to the monitor with green power light on. I have no clue at all. Who can fix this?

    Green power light always on. None of the buttons work--even power (always on). Plug it into a PC --- nothing happens. Help.

    I have the same problem, except that for some unknown reason, the monitor works properly at times. Still has buttons not working.

These are all some component failure problem in the monitor circuits. This may have been caused by faulty components or overheating of the components causing intermittent or permanent failure of some components in the circuits.This causes the feedback circuits to sense incorrect voltages or currents in the circuits and turn on the protection circuit. It may also cause total failure of the power supply circuit and a loss of power to the monitor. These units should be returned to dealers for servicing. Hope this helps you .

Hello when I turn on my monitor and computer this morning I have a black screen on my envision monitor and the green light keeps blinking do you know how to fix this


Unplug everything from the tower. Including power cord.
Press the power button for 5 secs.
Proceed to connect, power line, mouse, keyboard and monitor
That should reset the power or hibernation mode that you might have issues.
If everything looks normal, proceed to connect your remaining devices.
You must be aware that having a BIOS settings to boot from USB, DVD or USB-FLOPPY might prevent to boot into windows.

Envision en-7500 won't power on


The problem is in the power supply board, at least one capacitor is open, sometimes will bulge at the top making it easier to spot.

I have an Envision 7100 Monitor. Before going on vacation 2 weeks ago it was operating perfectly when connected to my Hewlett Packard PC. However, on my return the monitor screen remains blank (dark)...


The power supply may have become unstable due to bad DC filter caps, the power supply is always running 24/7 even when the power switch is OFF.
Look for bad cpas with domed tops.
If you are going to DIY and already try the monitor with another PC, 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/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Envision Monitor 22", when plug in the power core, the Green power light would blink repeatedly non stop. Screen would show nothing just a blank screen... it a one year old monitor, and was working fine...


Hi, when connected to a portable you sometime must hold function key then press F5 or F6 to switch between the portable screen and the aux monitor, have you tried the monitor with another computer. If this does not work, it might require internal repairs...

Won't turn on


This is a problem with either the power supply or or logic circuit. It could also be caused by a failure in the back light circuits. One of these problems has caused the power supply to go into protection mode and will not turn on due to bad voltages sensed in the feedback circuits. Return to dealer for service. Hope this helps you .

Envision EN7410e monitor


Just fixed mine. Maybe it's a few years late. Hope you guys still have the display. It's the power supply board. I've just replaced 4 bulge capacitors near one edge of the PS. They are 2x1000uF 10V, 1x470uF 25V & 1x470 10V. I salvaged my parts from an old CRT monitor. Hey you can go green with your repairs too!
