Part Number: DLP3000
Hello sir!
I would like to introduce, my name is Ngoc Tu, I work at the Photonics Center and I am a researcher. I would like to ask you about my problem. I have a kit light crafter 3000 bought from EKB, the more than a year my circuit has problems with the IC switch power from 5v -> 3.3V, I bought components from TI to replace but not have resulted. I used an external converter circuit replacing the switch from 5v3.3v. Initially light crafter 3000 worked well, but some time later came a lot of dead pixels. Today, I conducted the test for 3 hours light crafter 3000 operating, I found that the DLP3000 chip appears more dead spots (with attached images). I would like to ask you what is the cause of this problem, can I buy a replacement DLP3000 chip and the problem of dead pixel still appear? (I also bought a DLP4500 kit from TI) Thank you for your help. (My email: ngoctu2312@gmail.com)
Thanks to Paul Goedeke for the answer. I know it is difficult to predict the cause of the problem. Maybe I still have to risk a new DMD chip. I would like to ask more questions, if I wanted to buy a light crafter 3000 driver board instead of a broken electronic circuit, would the company provide it?
Last time the IC U15 was broken and I bought 2 new ICs, after replacing there was no 3.3v and I bought the circuit as shown below to connect to the general output P3P3V and GND, I think this is normal and no matter what? So the cause of DMD corruption is still unknown!
