How long did your HEM-711AC device work? The display on mine has conked out after six years; some black lines that form the numbers are now missing.

I've had mine for several years, but haven't used it too much. When I did, it worked fine.

I haven't had mine that long, but the unit is functioning great, so far. I do know that humidity can cause the problem you are referring to. I had another device with a similar read out that got wet. Maybe try this, remove the batteries from the unit and seal this device in a large zip lock bag with rice in it. This works beautifully for phones and for the device I talked about earlier. It's certainly worth a try.

I've only had mine for 5 years, and I only use it occasionally. That said, it still works just fine. Would you consider contacting Omron directly?

I know my response my hurt lovers of OMRON. MY unit stopped working within two weeks. Sent at my own cost to their repair facility in the USA, they sent it repaired back to me at without any charge of shippiing cost. We put in a new set of batteries and the unit lit up nicely but it failed to display the readings. Sorry, I got angry, straight away tossed the unit into my basement where it is still sitting without ever being touched. I did my research and bough another, this time from Panasonic well reviewed by Consumer Report. It is made in Japan. Beautiful unit, by the way it performs, I am confident it will be with us for a long time. Very dependable unit. Remy Salema I know my response my hurt lovers of OMRON.

Not sure about that but I hardly used mine and the display just went blank and became totally unusable - wont buy another again.

I would write amazon directly and they are good about working things out. I have used my monitor for many months and have no complaints. Could be the item itself is faulty. Also try notifying the company who made it.

Mine got a vertical and horizontal lines at the center of the display and I suspected that the damage is from shipping since Amazon did not double box it. Anyways, just get onto your amazon account and ask for replacement then amazon will ship you a new one. My replacement is double boxed and came in within two days.

yes. I have had two of these and the display stopped working after a few months.

Your display should have a blue background and should be super easy to read. Perhaps try replacing the battery and if that doesn't work, I'd request an exchange.

I was so happy with this monitor, i bought another one to extend the display. I use a laptop HDMI connection. But i am unable to extend the display on the two HP monitors. Second one is not getting any signals. Does anyone know how to make this work?

Happened to me too, after 2 years. I opened up the unit and as kaiser4 found out - a flimsy switch. and no way to just buy a screen!!

Hard to say from the information you have. Is there any way you can use a different monitor to see if it also shows the symptoms? Or if your goal is to keep the old monitor, is there a different source device you can try?

I'm sorry but I don't know. I never had that problem with mine. My problem was the LCD display showing erratic characters on it.

Nope! It's a throwaway. Only under warranty. What I did, I was lucky, I had a broken display. I found one on eBay with a bad USB cable. Only cost me $17 and I made a good one out of the 2.You should have been using a USB extension cable. Only a few bucks on eBay.

I find it interesting that this question came over my email a few days ago and I had also started having issues with my monitor too. For a few months when I turned on the monitor it would start going through the menus on its own sometimes changing the settings. More recently when I turned it on it would light up to start and then turn itself right off. The monitor worked pretty well for me up until about four months ago so it looks like once it passes a certain age or level of use it just stops working for some people

My last one lasted at least 4 years. Didn't replace the battery because someone stole it. New one work great. Started my Hemi the other day.

I, too, was curious if the ones being sold at the local stores were the "N3" model -- even though the boxes give the part number as "HEM-780". However, the back of the box shows that they have "TruRead Mode". I decided to purchase the one at Walmart (7-27-2008). The back of the control unit says it's an HEM-780N3. So far the unit is working well, and the readings seem to jibe with an older HealthCheck blood pressure monitor.

The display can be replaced by Garmin. They have a repair/update policy that will take care of your problem for $99 + tax. Contact Garmin.com with your request.

I'm using the OMRON HEM-773 monitor and it seems to work. I'm going to take it to my dr though to make sure it does correctly measure.

good afternoon, thanks for asking I live in Venezuela lcd, get me a month ago by the inconveniences in the country, but I have two weeks of having the screen installed in the cell and the lcd is presenting as red lines that cross images and also if I have a long time with continuous use the lcd starts to lose color. I can do in that case? thank you
