    Re: Computer Monitor Conversion AC to DC

    Something fishy in the spec, it says 5V, 500mA USB powered, but the power consumption shows "Power Consumption: 4W-5W " How can you get that much brightness and power to run all the logic at 2.5W (Max power for one USB port), unless it uses one of those USB Y cable to use 2 USB ports to get enough power to run it. You may be able to get car adapter that convert 12V to 5V for it.

    The on/off control of the backlight can be done by using a switch and a pot for adjusting the brightness of the backlights.
    Does you monitor look like one of these ACER?

    Thanks for that. I've order the inverter today. I will give it a go.
    The monitor is anAL1716 A and version AL1716Ab whatever that means.

    Have you seen these? I couldn't find anyone who retails them.Only two wholesalers in China. You can get 8" and 10" versions as well.

    Had a bit of a goosey gander under the bonnet and realised it's out of my league. Maybe I should track down a 12 volt monitor. Anyone know of such a thing, brand etcetera. I did a google without much luck. Surely boaties must use something along this line other than a 12 volt TV.

    This one is internal and I was hoping it would be a matter of bypassing a 240V external supply and attaching to the internal power supply and hoping it would be 12 volt. I have made a couple of 12 volt variable power units which knock down to 3 volts by turning a 20k variable type resistor. So really I need to open up the Acer Screen and take a look inside. I really wouldn't know where to start looking but I will give it a try.Any advise would be grateful.

    I'm trying to avoid an inverter and make by whole internet system 12volt Unfortunately my system is too small by converting with my 150watt inverter.
    I checked out the Acer screen and it takes 1.2 amps DC when its plugged into the inverter. I can measure amperage usage with my home's 12volt regulator's display, and which is connected to my small battery bank.

    Computer Monitor Conversion AC to DC

    I have an external Acer AL1716 A 240 volt AC monitor attached to by wee netbook computer which I was wondering if it can be converted to a 12 volt DC powered monitor. I haven't pulled the Acer monitor apart yet and thought perhaps I should ask here if anyone knows a little bit more about the unit before going to the trouble to see what's inside.

    Aorus 17G YD laptop, broken display, could not switch to external monitor
    by ArchangelGabriel
    Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have

    How to force Acer Aspire Series to bootup BIOS/UEFI on external Monitor?
    by maralexbar
    I ask this question in general as there are many Acer Aspire models with UEFI Insyde BIOS that do not boot to the BIOS on an external monitor (VGA, HDMI, etc) showing only the Internal LCD (LVDS, eDP etc).
    It's a pain to work on Acer notebooks with a broken screen and not being able to access the BIOS using an external monitor.

    If anyone knows how to force the external monitor as primary for Notebooks of those models

    HannStar Hanns-G HC194d LCD monitor repair
    by momaka
    Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

    external hd Seagate, broken down the +12 volt and USB 3.0 SATA board
    by gabri2211
    Hi to all 😎
    I'm looking for any useful information to repair this interface (I have attached the image).
    On this board I read E3215-1215A_4D.
    This is the small plate inside the HD enclosure that allows to connect a 12 volt power supply, interface the disk with a USB 3.0 socket and is connected to the HD with the SATA connector.

    If any of you have found a burnt or short-circuited component in a circuit like mine​, if you have useful diagrams for the repair, or even better a description for the tests at the test points, I would be very grateful.
    in particular...
