The board has gone out and I cannot find a replacement board anywhere. I've searched and searched and have attempted to contact AOpen multiple times with no luck and cant seem to find this board anywhere. I was hoping maybe someone here knows where to find one. The model on the board itself is JT198AP 2202126501.

Its very simple Solution.. simply open cabin cover and take ram out and clean ram slot and ram and wait for 5 min and reinsert ram into ramslot.. and switch on computer... if same problem continues repeat it 2, 3 times.. still problem continues contact me email@example.com
It may be worth a shot, but before you give it a go, I'd scrounge up any info you can on your florescent backlight (power rating, input frequency, ect.) Take it out carefully and see if it has any markings. Then you can use a multimeter to test the output of the MV176. If you end up ruining the light you have, you could always try and obtain the MV176's bulb and attempt to install it along with the inverter.
Check the power supply first for bad caps, then check to see if you do have the 5v (for logic circuits) and the 12v (for back ligjts inverter).See example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
This is a common problem on these monitors. There are three or four
capacitors in the power supply, three on the inverter board and anywhere
from 2 to 6 on the main board that go bad.
The number on the main board depends on how long the monitor has been
having problems before it was serviced. The longer the wait, the more
capacitors will have gone bad.
The power and inverter boards are easy to repair, the main board is not.
As mentioned, it is a multi layer board so removing the old capacitors
and the old solder can be troublesome. I would suggest you have someone
experienced at soldering repair the main board.
Btw, our shop would charge $60 labour plus $2 for each capacitor.
This is most likely the power inverter board in the monitor - this is
common in many monitors. If it started taking longer and longer to
display an image, and the power light is blinking on-and-off, that's
most likely the problem.
You can confirm that it's actually the monitor and not your computer
or the cable by plugging in another monitor if you have one to try. If
it's under warranty, send it back, if not, there are inverter boards
for many common models of LCD monitors that are replaceable. The board
can run anywhere from $50 on up. Depending on how old your monitor is,
and how much you've invested into it, you may find it better to just
replace it with a gently used one from ebay.
the capacitors are bad those are the only thing that need replaceing, the componenets on the board are likely fine if you like we can arrage a deal and you can ship me the boards to repair them let me know
Your inverter board is bad. They run anywhere from $30 - $80. They are very easy to replace. I have had this problem with three monitors and replacing the inverter board fixed the problem. Hard to say where you will find the part. Just do a search for 'inverter board' with your model # on any search engine.
