The final video in repairing a viewers BenQ W1070 that was hit by a power surge via an HDMI port. It originally seemed like a color wheel error. However after deep troubleshooting and measuring voltages, I found a bad HDMI chip (ADV7612BSWZ). After installing the HDMI Chip, I found some bad parts in the HDMI 2 channel. I referred to the schematic and was unable to determine one of the chips but decided to try it without the chip. It worked! I suspect the chip is for HDCP compliance but I am not sure. I am sure however that the input works with most video devices. Also the HDMI 1 channel is fully functional with its own unidentified IC. If you need a lamp for this model you can get one here. https://www.purelandsupply.com/benq-l... Part 1 • BenQ W1070 DLP Projector Repair / No ... Part 2 • BenQ W1070 DLP Projector Repair No Li...
