Screen went blank and orange light is on


fiona_sheeha, If ACER warranty service not an option, then unit will need local tech to troubleshoot unit's power supply/inverter circuit for possible COMMON and repairable printed circuit board fix. You must read more of my fixya profile and visit the web links you find there so you will know and understand what ALL your options are!!! Some units require less than $5 in parts to refurbish them to working status. Your "cold-cathode-fluorescent-lamp" backlit LCD monitor isn't any different than any other brand of monitor in it's basic operating principles!! I hope this helps. 12fixlouie

My monitor just went completely blank. There is a


Hello,

The ticking sound you hear is from the power supply trying to power up. If you can solder you should be able to repair the monitor yourself. The problem is caused by blown capacitors on the power board. Go to our web site at : www.ccl-la.com/badcaps.htm We have pictures of what to look for. Open your monitor and look at the power supply board for any blown capacitors, replace all that you find. The replacement parts can be ordered from several places on the internet or we can supply them for you. The replacement parts will need to be high temp and will be marked 105c. The values you need to get will be marked on the sides of the ones you take out but will be something like 220uf, 470uf, or 1000uf etc. and then a voltage rating. When you install the new ones be sure to insert them with the polarity stripe going the same direction as the old ones come out. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping. If you have any questions just let us know

I hope this helps if so please rate our solution.

Hp w2207h screen in blank but flashlight shows icons are


The power supply-inverter board is probably at fault. Remove the back cover and locate the standard ac power cord connector. The board that the power input connector is soldered to is your power supply - inverter board. Check the electrolytic capacitors on the board. They probably went bad. A visual inspection is usually enough to find out which ones are bad. They will be either bulging or cracked at the top and leaking fluid. I usually replace all of the capacitors that have the same rating whether they look bad or not. Will save you another repair later. If the caps don't look bad, you can take the board to your local tv repair shop and have the caps checked with a esr tester. It's more accurate and they can be tested with the caps in place. Hope this helps.

Monitor Screen goes black every few seconds!


Check the capacitors on your monitors circuit board. If they have opened up at the top, they are fried. Buy new ones, make sure nothing has leaked from the old ones, and replace them.

Blank monitor


Try unplugging the power cord to your computer tower, click the power button to drain the capacitors in the mother board then plug the power cord back in and try to boot up. Has helped me repair several similar black screen problems. Chuck Housecall101@aol.com

Dell 19" Monitor - Dead


Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it went blank, you have to check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like mine, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you,
Tan

Had a Acer al2017


If your picture was okay when it was running and the screen was not pinkish then the power board inside the monitor is in need of an overhaul.
Your unplugging it and plugging it back in just did a temporary reset by discharging the capaciotrs for a bit.
It more than likely needs new capacitors installed.
I have done a few of these and do a lot of inverter power board repairs through ebay id bammbammfran

Problem in monitor


Sounds like the inverter board or lamps are bad

No Display


I have the same problem - the blank/black screen and blinking green power light. The speakers on the monitor work (I can hear the start-up sound that Windows makes), but the screen is blank. We bought the monitor on Halloween Night 2003 at Best Buy and had zero problems to date...except for last night. The Best Buy gang told me this afternoon that it was an internal hardware issue. I called the manufacturer and the tech guy confirmed the problem by saying he was almost positive it was the internal "inverter board" - which means you have to send it in to get it fixed. I guess this is a fairly common problem with these monitors by the way he made it sound. So, that's a $70.00 deal (service, parts, labor, and shipping back to your house) - that is, if there are no other issues with the screen itself - then the cost goes up. So by the time you pay to send it to them and then pay them to fix the board - it looks like you're better off buying a new flat panel monitor. Yikes. Anybody else with any suggestions - other than buy a new one? Thanks!!
