Envision H170L Monitor Questions & Answers
How do you take the base of a envision H170L
Can't find too much info on this monitor. Look for a crease/gap in the plastic around the neck of the stand. Most likely a plastic cover is covering the screws you need to unscrew. You'll probably just have to pop it off.
You may have to first remove the flat part of the base (if looks like it separates from the neck). Check the bottom of the base for tabs or plastic clips holding it to the neck. If the flat part of the base doesn't come off, just look for the plastic covers mentioned above to reveal the screws that are holding the base on.
Resolution Notice
try lowering your resolution all the way to VGA and work your way up the resolutions. Also try checking your geometry (16:9 or 4:3 for example)
Hello:
the auto adjust keeps flashing
Hi
The Auto adjust button might be sticking or stuck misaligned with it's slot on the frame.
The computer's graphics resolution setting might be straining at the limits of the monitor's capability.
Try diferent resolution settings:
Right click on the desktop > (Properties) Personalize Settings > click, hold and slide the slighter and test variour resolution settings.
If you find a resolution that the monitor is happy with but does not satisfy you, you may need to consider a higher resolution monitor.
I hope this helps
The Envision H170L Monitor VGA cable.
the Envision H170L Monitor uses an interface 1.0x VGA - 15 pin HD D-Sub (HD-15). The same VGA cable wildly use in different computer brands..I was wondering why you have not found a replace for that cable. It can be purchase from any computer store.
If you are planning on cutting the wires and solder it together that would be easy if you have the diagrams of the pin numbering for
male VGA connector and the
female VGA connector. Check first this diagrams and follow strictly the coding of the wire so that it would be successful when connecting it together.
It is also better if after you solder the wire, you will use an shrinkable tube on the connection. Cover the whole sections of interconnected wires with shrinkable tube before you use the vga cable.
Display probs
Try the monitor on another computer; if it works fine, then the video-card on your computer is the problem.
If it does not work, then it's time to buy a replacement LCD monitor.

jsnent1, If monitor has manufacturing date close to 2006, then unit may have problem internal to it's switch-mode-power-supply. If smps dc output gets noisey due to bad or failed filter capacitors strange things may start showing up on-screen of lcd panel. Technician will need to evaluate unit and repair it. At least do another post and give me some history of unit so other readers will also know what to do if this problem occurs with their units. Also tell us the date of manufacture from rear cover of unit. 12fixlouie
I have an Envision H170L monitor that goes dark
http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR MONITOR
take your plate a part, without desolding anything, reconnect your ccfl's to your invertor , this is how I found that with only 3/4 my monitor ccfl backlights worked. Monitor had classic for 2 seconds and I coud see a windows shadow (I changed my capacitors).my was a kit assembly plate and disassembly easy, light clips and small screws, gentle, movements, set your work bench very clear, tube break, push from the sides where they plugged together always!
I guess from this that the inverter self test check all the ccfl's!
hence the on / check/ off screen (the high power bit, leaving the lower power bit on)
No signal
Please check whether the VGA cable is connected properly.
Screen Keeps turning off after about 1 second
willie114, You have typical problem of lcd monitor failure. There is only one further test you can do. Reconnect H170L to an already fully booted pc with WIN-Desktop showing. then and only then turn on H170L. As soon as screen goes to BLACK, shine bright flashlight 1 -2 inches from screen at different angles. You may or may not see the desktop screen even though the screen is black. If desktop can be seen it only means that the power supply is still powering up the digital lcd driver board. The problem is that your long, thin, Cold-Cathode-Fluorescent-Tubes are not lighting up due to a problem with the Inverter Supply that feeds AC to power the lamps. The inverter gets DC from the Switch-Mode-Power-Supply. The technology your are dealing with is similar to the new energy saving curlieQ screw-in replacement light bulbs. Only your tubes are straight and hung left to right horizontally in back of the lcd and their power source is a bit simpler and called a converter. AC to AC. Get back to me and I will let you know of your options as a consumer/user whose screen has gone to BLACK. I'm louie12fix on fixya or lmistyrel@ aol.com Bye for now
H 170 L-17" monitor
If *nothing* displays on your screen, the most likely problem is your LCD Backlight Power inverter. If the backlight power inverter is bad, you can usually see some remnants of an image on the screen if you shine a light on it. If the backlight power inverter is bad, it may not be worth repairing on a 17" screen, considering the low cost for a new one.
It should be noted that Envision provides a 3-yr warranty for most LCDs, so contacting them for repair may be a good option. More information here:
