I used a 12v@3A laptop battery and the screen refused to display video, what should i do?

Could be several things, camera not working or hooked up, how about common ground, use the 2sd video to test for bad input fault. Sorry can't think of anything else.

I was able to use this with a 7.2v battery running at 2.2 amps, are you sure the video feed is working? if it is then you must have a faulty screen.

Did it power up? Mine cane with a power source and I successfully used a 3S Lipo battery.

I had the same exact problem, I don't know specifically what it is but it requires a higher amperage.

No, you would need a new LCD screen. Additionally, you might have a damaged main-board, this is something you have to test for.

I would check the voltage required for that laptop including the amperage needed. The one I bought is still working but it's low amperage. So it runs very hot and sometimes the screen will flicker.

We installed the new battery and when we started pedaling the display came on. If you've tried pedaling and it didn't light up, I'd start by checking to see that the voltage at the battery is good and if it is, there may be another problem.

make sure it is connected to a video source, yellow plug. other than that i dont know. maybe defective? i would try a few different things before sending it back. turn it off then on, letting it warm up, etc

I have a similar issue. Although it worked fine on Christmas day, batteries lasted for 4 hours only. Put a second set in later the same day. Screen has been flickering ever since. Yesterday, tried to turn it on and blank screen. It is still working as you can tap the screen and it moves on, however, nothing can be seen. After and 10 minutes, it seems to come on but it seems like there is a loose connection in the display. And when connecting via the USB connection, it is not recognising the unit. My problem is that I purchased the unit in US while on a business trip, but live in Ireland! I am going to contact Vtech in the UK to see if they can help. I have a similar issue.

Unplug the lcd connector and plug it back, but if that doesn't work probably is the lcd problem, try with different lcd

Yes and no. Check to make sure the wiring "thingy" is properly connected where the screen is being attached. It was hard for me to connect it back. Hopefully the wire isnt damaged. If u were to plug your old screen back I and it comes on then thsy may have sent a bad screen/wire "thingy". Hope this is helpful. Sorry I don't know the correct terminology, but I was able to successfully replace two of my laptop screens. Good luck!

If the refresh mode does not do it the battery may be be young hope. You can always try flashing a battery. For that procedure, check out tube videos

Possibly the display is frozen. Removing and reinstalling the battery is worth a try.

What exactly is your question? Check your power supply. Make sure you have 12v. If you can confirm that then meter the ends of the longer 20 ft cable to find 12v as well. If confirmed there then may be an issue in the camera

Could be a bad screen, do you have anything else to tested it with? Also double check the cord on both sides is secure, one side going into the new display other side going in motherboard/graphics card.

Buy a new one. It cost about the same for a new screen. Hopefully you bought the warrenty

Did you put the battery in? The meter on mine quit working after a year or so but unless you record your mileages and times ii's no big deal at least to me. Otherwise call the company and request a new monitor

We didnt it wasnt neccessary, but i also knew that it was only my battery that was bad. You can use the old power supply cord if you didnt have problems with it like a short in the wire or something, otherwise replace it too.
