LME tech support-
I almost can give a conclusion for your problem.
You checked the voltage around LME2510C and it is good. and picture shows that the VID_0000 and PID_0000, it means taht the LME2510C doesn't work.
Please check the voltage of Pin18 (RESET) during you plug in the USB TV BOX, normally it should be 0V after a short time 3.3V. but maybe it is difficult for you to test it, because it only can be captured by oscillograph. if you don't have the oscillograph. you can directly change C314 and R310 and check again to see if the TV BOX works. if you did all and it doesn't work yet, there is only one result: LME2510C is broken. and I will send you some good LME2510C , you can replace it yourself and I think the problem should be solved.
OP- note you find this by clicking on "Unknown USB Device" and following path to "Device Instance Path"
Seems strange to have bad Xtal and uP on same board. |
