Hello. I have the above monitor and was told today that I need a new inverter. When trying to come on, the monitor will flash on & off very quickly and do this over and over. Where can I get this part and is this fairly EZ to do myself if I know my way around a screwdriver?

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 ENVISION 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. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
Please verify that it does the same with other PC.

catamount309, This is only a guess, but unit may have internal "switch-mode-power-supply"/"CCFL inverter" board problem. When screen goes BLACK, is it also BLANK? If you can see WIN-desktop with aid of bright flashlight 1 inch from screen, then SMPS is in partial shutdown mode. If you see nothing, then SMPS is in full shutdown. In either case, Technician will need to repair the SMPS/CCFL inverter board. If KNOWN GOOD monitor works with PC, then you know 7100e is bad. Do you know and understand how the new energy efficient screw-in curlie-Q light bulbs work? If the "electronic ballast circuit" not working, then it can't light-up the CCFL tubes on the reverse side of LCD panel then you see black. Do more reading in my fixya profile for more options open to you. Do your research first!! Hey, reading is free!!!
Will you fix or trade for new? 12fixlouie
davagain, Just now saw your new post above. If you are intent on delving inside your unit, let me caution you to be very careful in doing the disassembly. Above all else, you must take care to not do more harm than good!! That said, you should try to find and view some video clips on youtube that will demonstrate LCD monitor tear-down. The ones that are >8 -12 min run time should be of help in your quest to "PART" the rear cover from the front BEZEL which holds the LCD panel. Right now you are at the most difficult and dangerous STEP!!! Use extreme caution in any further disassembly procedures. There should be no need to remove panel from the bezel. If digital camera is availiable use it to do your DOCUMENTATION of how things came apart so you can reassemble without having "LEFTOVER" parts. Good luck guy. Do you have a large magnifiying glass to inspect soldering of the printed circuit boards? get back to me with results of inspection. louie12fix or lmistyrel @aol.com Bye for now.
cmgusa, Reconnect 9410e to original PC. Please note if same symptom occurs again. This sounds like an intermittant or failed solder connection of some component on the inverter/smps power supply board. Have you tried the FLASHLIGHT test when the monitor goes to a BLACK screen? You did not state the approx # of hrs of use this unit has on it. The Flashing you describe is most likely the cold-cathode-fluorescent-tubes trying to start-up. If they don't light then you get a black screen. They (CCFT) get their voltage from the inverter section of the power supply. But anyway... Your options as a consumer/user are as follows. Check with Envision to see if they have a swapout program... you send them your 9410e +$50-$90 and they send you a REFURBISHED 9410e with 30-90 day warranty. or Find local TECH (TV-Monitor) who knows forward and backwards all there is to know about repair of LCD monitors. There are some very good tech's right here on fixya that could do the repair and not rip you off. Last but not least is try to effect repair yourself. If this last option is of intrest get back to me only after doing web search of monitor disassembly video clips on youtube and doing search for things like bad caps or recapping and inverter repair + have a minimal understanding of how a SMPS/inverter powersupply functions. I'm louie12fix on fixya or lmistyrel @aol.com Bye for now.
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:
