Other Parts Discussed in Thread: DLPA2005, , DLP3010
Our projection products have normal working well using DLPC3478+DLPA2005+DLP3010LCFQK.
But only one that domestic customer returned has a question that the product project checkerboard all the time after power-on.
We had to disassemble it and found only the chip of DLP3010LCFQK is unusual. It appears the pattern of checkerboard on the top without power supply and as shown in the following figure.
We have to change the DMD chip many times and this product normal work all. So we question our OEM factory about this product. the record of this Mainboard display that it replaced DMD, and the phenomenon is same as the one that customer returned.
By the way there were 3 pcs in Europe that have the same problem.
we want to know :
1) why the checkerboard phenomenon occur?Now, the DLP3010 chip is destroyed or gets into the special mode?
2) how do we solve this problem?
