Just because you got the screen from the same seller does not mean it will be the exact same display others got.
If you did everything right and it does not run on 5v, try 12v and if this fails it is DOA, if only 5v does not work,
it is not broken but rather another version.
The chinese manufacture a lot of those displays and if a shop buys a lot of them, they order from several factories, because most of the time they only produce small amounts and can't produce large quantities.
Thus some sellers offer the same display with different boards.
Check if you mixed up some wiring and try 12v. If this does not work, maybe post a good picture of the board.

Re: BW var 2. Broken out of box or am i missing something.
All good advice. Just adding a touch to it. Do not open the casing, don't look at the board, don't do any modifications until AFTER you've confirmed that it does turn on and work. Find an A/V output (I use my wii) and a 12v power cord. Check to see if it runs. Then, after you confirm it turned on. Find a 5v power cord and repeat the test. If it doesn't turn on, that's fine. It just means you'll have to figure out how to make it run on 5v (if it even supports it). The emphasis here is that you checked that it would turn on before you modded it, so if it was DoA you could return it for a refund/replacement.Fleder wrote:Just because you got the screen from the same seller does not mean it will be the exact same display others got.

Once it runs on 12v, open it up and have fun either getting it to work or breaking it (hopefully the first).
