Hello,
I have a problem with BBB + BB-View + LCD7.
OS: TI-SDK from element14 site
HW: BBB “PCD Rev B4”, Element 14 BB-View cape, 7" LCD “LCDX000-70T”
- Colors are strange. Looks like not enough color depth or wrong blue color intencity
- When I place my hand near the cable, didn’t even touching it, blue color noise appears.
I’ve checked all connections. Everything is good.
Board powered from 5V 0.5A DC adapter. I know that it’s not enough, but it works.
Have somebody met such problem? What can I do to fix it or just to find the reason?

I’ve reconnected internal LCD cable. Blue color appeared and blue noise disappeared. But there is still not enough color depth.

Just so people can help you, can you tell us the revision of the board? PCB Rev B4 is the PCB, not the board. The revision is either on the expansion headers or the RJ45 connector…

There is no revision like “A5” or similar on board. I have BBB from Embest with XAM3359AZCZ100 processor. There is nothing on ethernet header. And it has barcode and code “1001024” on expansion slot.
OK. So now everyone knows you have the Embest board. Interesting that they have no revision number on it. I don’t know what revision that board is equivalent to on the BeagleBone Black.

After 5-7 reconnections of BB-View in expansion slot it looks better, but not 100% ok. I think, the problem is that expansion connectors on BBB and on BB-View has bad electrical contact. Is it common situation for BeagleBone Black, or just for Embest replica, or maybe for my device only?
Stupid Terraelectronica sells crap 
Can somebody suggest board manufacturer which have no such problems&
Original bbb does not have such problems
