请问怎么联系Ti的售后维修

购买的DLP6500FYE，主机与EVM连不上，确认USB线没有问题，怀疑是电路板的问题，请问怎么联系TI售后维修，或者请教怎么将主机与EVM连接，软件是3.0的，主机系统是win7，都连不上。电路板各指示灯都正常亮，上电以后DMD自动运行，说明DLPC芯片正常工作。

您好！
感谢您使用TI的DLP产品。这是DLP6500的start顺序，请问是否完全满足？

Power-up the DLP LightCrafter 6500 or 9000
The DLP LightCrafter 6500 and 9000 are ready to use, out of the box. Steps 1 through 6 show how to
power, display an image, and connect the EVM to a PC.
1. Connect a 12-V DC power supply to the power supply connector J17 in Figure 1-5 or J20 in Figure 1-7.
2. LEDs — D8 and D9 on the DLP LightCrafter 6500 and D5, D11, and D12 on the DLP LightCrafter
9000 — light up green to indicate configuration and power is normal.
3. LEDs — D6 on the DLP LightCrafter 6500 and D7 and D9 on the DLP LightCrafter 9000 — toggle on
and off, indicating DLPC900 is operating normally.
4. After 5 seconds, the DLPC900 displays a continuous pattern sequence.
5. Connect a USB cable from a PC to connector J7 on the DLP LightCrafter 6500, as seen in Figure 1-5
or J8 on the DLP LightCrafter 9000, as seen in Figure 1-7. The first time the cable is connected on a
PC, the DLP LightCrafter 6500 and 9000 enumerates as a USB composite device with humaninterface
device (HID) class. No drivers are required since these are natively handled by all operating
systems.
6. The DLP LightCrafter 6500 and 9000 EVMs can be controlled with the free GUI
是否尝试更换USB口，重装GUI，或者更换PC的情况？
