Re: EN-7100si


NO.. Do not replace the LCD panel, nor the chip that controls the backlight (there is no such chip anyway), nor the backlights themselves, as none of the above are broken.

There are some capacitors on the low-voltage side of the internal SMPS. One or more of them is bad. Most likely, you will be able to see bulged tops on them. Replace them with identical uF rating and same or higher voltage rating, making sure to get the polarity correct.

About the only CORRECT thing I've seen in any of the other replies to this post is that the problem is common among many LCD monitors. I've personally repaired five of them in the last three days.

Re: EN-7100si

Had exact same problem........
Pharkus was right on. Replaced the 1000uF 16V and the 470uF 16V caps next to the largest/yellow transformer. One at the top and one to the left. Works like new!!!
Thanks Pharkus!!!!

Re: EN-7100si

This problem is common between a multitude of lcd's i am pretty sure that it is either a lcd bulb problem (mini floresent) or the chip inside the monitor that corrects the amount of power the bulb gets. I have replaced bulbs for these and it has fixed this problem.

I have a en-7100si monitor. It has been working just fine until this morning and it does not power up. when I turn it off and then on, it will flash the screen picture then go black. Can you help? ...

HI there,

I fix many lcd screens
i can tell you that its usually a result of the capacitors going bad.
If you dont mind taking the screen apart you can fix it yourself for around £3 providing you have a soldering iron and supplies.
If not you can buy a cheap iron for about £10 from maplin or similar shop.

Any caps that look buldged have blown and should be replaced.

It seems to be a common problem with your screen, you can find more information at the following link

Hope this helps

First, if it shows no signal because it is not receiving the signals from PC then it will go into stanby mode. Try it with another PC first and also check the cable.
Most capacitors kit costs around $15 if you replace them in a set, I always replace them in a set.

Learn about bad caps:

Capacitors kit: he can make you a set of caps for you.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
Post back what you find.

Black/blank lcd screen after 2 seconds

try this - boot into "safe mode" - (this loads just minimal drivers). Reboot and press F8 while it's booting - it will ask if you want to boot into safe mode - say yes - if the screen works with the low resolution inherent drivers, it's probably a driver issue, or if you have a video card, it may not be able to work at the higher resolutions (which could be a card issue)

This should help you narrow down if the screen actually works, or if it's a graphics card and/or driver issue.

If it works - try reloading the driver for your graphics card (if you don't have a graphics card - try reloading both the chipset driver and the video driver from the manufacturer)

let me know if this works...

(I had a Toshiba Tecra laptop that did the exact thing - you could see the Windows boot menu, and once it completed boot up, the screen would go black - if you started it in safe mode (crummy resolution) it worked but of course the graphics are unacceptable at that resolution)

Turns out this is common with those, it was the graphic card built into the motherboard that's shot....

Lower half portion of the horizontal screen black

hi rafi,

check if problem occurs with another computer, hook up another monitor to your computer to check if your graphic card is making trouble.

if it the monitor, and it still is under warranty and you did not damage it, just return to place of purchase and let the paid pros work their magic1

Good luck

When I power up my PC and monitor, the screen comes on for a couple of seconds, then it goes black

this happens with a few monitors and some graphics cards. if you connect your monitor through a DVI cable, try connecting it through an analog cable. if possible change your graphics card, that should solve it completely.

Monitor screen stays blank

HP desktop computer? Change the monitor cable. The cable from the monitor to the computer, may be bad.

If this doesn't solve it then I suggest the GPU is bad. Graphics Processing Unit. If you have Integrated Graphics, (Also referred to as 'On-Board'), then I suggest buying an average, inexpensive graphics card, and installing it.
You'll have to see what expansion slot, your computer uses for graphics. It may be a PCI slot, or an AGP slot, or a PCI Express x16 slot.

Clear as mud on that last one? Let me give you some links, that might help clear up what an Expansion slot is, and the three types of expansion slots used for a graphics card.
1.Expansion slot:
2.PCI (local bus):
The link above (No.5) shows a photo of an average motherboard. At the top right you will see two White slots. Those are PCI expansion slots.
Below the PCI slots is a PCI Express x16 slot. It is Black in color.

Envision EN 7100si LCD 17" flat screen

First try auto-adjust with the auto button on the screen
if not worked

Make sure she installed the envision driver. I jus saw it's a discontinued product. Also this product has a maximum resolution of 1280 x 1024.

If installed check her resolution. Right mouse click on desktop>properties>screen. Try alternate resolutions and see what happens but don't set it higher then 1280 x 1024 if possible.
