No power to monitors, but blinking led on ac adapters.
I unplugged the power cord before going out of town. When I plugged back in there was no power to the monitors. The ac adapters have blinking green lights and a ticking sound. Both of my monitors are fairly new.

Re: No power to monitors, but blinking led on ac...
Try replaced with a new AC Adapter. If it still the same...then you got a busted backlight inverter. To order a new AC Adapter go to this site @ www.3rd-rocks.com click on lcd parts. have a nice day!

Your manual is here. The section on charging states, that green blinking means your battery is fully charged but blinking red means that your charger is faulty. I would say repairable.
1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet.
2. The On/Off LED indicator is blinking RED, this is abnormal. Unplug AC power cord from the on-board battery charger and wall outlet. Charger may need to be replaced. Contact an Invacare dealer or qualified technician.
3. When the On/Off LED indicator light is Off, charger is Off.
4. When the Charge LED indicator light is YELLOW, the batteries are charging.
5. When the Charge LED indicator light is solid GREEN, the batteries are fully charged (as their condition will allow).
6. When charging is complete, unplug the male connector of the AC power cord from the wall outlet and then unplug the female connector of the AC power cord from the AC receptacle on the charger.
Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized. (Will charge)
That is AC adapter (Charger) removed, then remove multi-bay battery. Plug AC adapter back into laptop, THEN plug AC adapter into power.
[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]
Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter. (Then plug AC adapter into power)
Symptoms of a broken power jack 1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker. 2. Battery will not charge in the laptop. 3. Laptop runs fine off a charged battery. 4. With the AC Adapter connected the laptop appears to be dead. No power LED or battery charge LED activity. 5. Laptop randomly powers off without any warning.
If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it
Usually, after a power outage, a power spike (when the power returns) can disable/blow the fuse in the AC adapter for the Wii.
- unplug the Wii's power cord from the wall, and leave it unplugged (from 5 mins. to 5 hours). Then, plug it back into the wall. (Unplugging the power cord from the back of the Wii will not help. You need to unplug the power cord from the wall.)
- This usually helps reset the fuse circuit in the AC adapter, and your Wii should work again.
- THEN, buy a SURGE PROTECTOR power bar, and plug all of your expensive items into it (to prevent this from happening again).
- open the panel on the AC adapter box in the power cord; since the screws are proprietary, you will need to creatively use existing tools to turn the screws
- check the 3A fuse in that box; if it looks blown, then replace it
- it might be cheaper to replace the AC adapter with another one
This monitor is plug and play but the driver (or lack of) is not the problem. Its either your the power supply or the monitor itself has an issue with its internal power distribution circuitry. First make sure your power supply is operational. The original 120V AC to 12V DC 3.3 A power supply for the B70A had a green LED on the brick itself. You will find it on the top right corner of the brick, on the end where the DC cord comes out (opposite end from the AC input) If you have the AC cord plugged in the wall, the LED should be lit. If it isn't, the brick is no good, and should be replaced. Any 12 VDC adapter with an amperage rating of at least 1A but no greater than 3.3 A having the same size tip (with correct polarity) should work. If you have confirmed that the adapter IS functional and the monitor LED's still remain off, the internal power distribution circuitry of the monitor is damaged, probably caused by burst or leaking capacitors.
It seems to me the LCD cable is either not properly unplugged or LCD ha gone bad.
Connect external monitor to the laptop and check if you have the Video on the external monior. If everything looks fine on external monitor then you can get the LCD replaced.
In case system does not power up and there are no indications of power.
Here are the steps:
Connect only the AC Adapter and take the battery out.
Check if you have a green led lit on the AC Adapter.
If AC Adapter does not has a green led please replace it with a known good AC Adapter.
If the AC Adapter has a green led but still no power it can be the system board which has gone bad.
Remove the battery and unplug the AC adapter. With the AC adapter unplugged from the system, plug it into the wall, see if the power LED comes on. If it does, plug it into the system and see if it goes out. If the LED never comes on, or goes out when connected to the system, replace the AC adapter.
If the LED stays one, see if the system will power on and give any indications of power at all (Flashing Caps Lock, Scrool Lock, Num Lock LEDs) If no power indication with a good ac adapter connected, then the motherboard is the next item to replace.
Either item listed above can prevent the battery from charging. So the battery is the last item I'd replace unless the system turns on with the battery out of the system.
If it flashes ON and OFF when simultaneously unplugged from both power and the computer then it's trying to communicate with you.
Mine flashes code to me. It tells me what to do. Last night it told me to get it $5,000,000 in unmarked bills.
Seriously, turn the monitor on without connecting it to a computer.
If it flashes ON and OFF continously, then you have either a bad monitor or a bad AC/DC power adapter/brick (you know, the rectangular black corded adapter you plug into the wall outlet).
If it only flashes ON and OFF when connected to a computer, try the monitor on another computer.
If the monitor is 3-4 years old, it may be time to replace it since a replacement AC/DC adapter might be very hard to find.
Let me know what you find out, if you need more help.
