Finally figured out why my projector had an internal error. After inspecting the top board, I finally took the under board hardware/rails off, and long an behold a burnt SIL HDMI chip, and what looks to be a burnt eeprom chip.
It is clearly burnt off HDMI input 1, although the connector, and other traces appear well. I'm not sure if this was a random power surge/component failure, or if the heat from the bandwidth these things run caused it to fry, but it looks dead. Epson doesn't release schematics, so it maybe tough to fix, but I've ordered the burnt Sil chip, and have yet to figure out what type of IC the 8 pin burnt chip is. Any idea?
Of course I will check all the traces, and other components in the chain, but hard without schematics. I bought a refurbished projector with a warranty and will use that board to do my comparisons to.
I'm concerned that if this was not a random failure of a component (none that I could trace) to the power supply, why would it die/burn this bad?
Could this be a result of the heat from maxing out the HDMI input 1 - linked to both Sil chips (Burnt one is SIL9679CNUC)?
Hdmi 2 does not appear to trace to the burnt Sil chip
Just a caution to all of you that are maxing the bandwidth/HDR/etc and pushing the projector to its max.
