DLPLCR65EVM: DLPLCR65EVM error

Part Number: DLPLCR65EVM

Dear Team 

Good day!

Our customer order 2 DLPLCR65EVM 2 years ago , recently , one of them went error  .

When they want to  output the desired graph, it displays failed!

When they want to choose "normal" and "pattern on the fly mode", it will jump back to "standby"

Another one work fine , they had compare the LED state when they power on , they are same

They want to confirm that which component broken could cause this happened , how to check it , I found this product had been sell the Controller Board and the DMD/DMD Board separately , I can't find the original instructions.

Could you provide any suggestions?

BR,

Leon.liu
