Epson projector not work HDMI

[3cxmostar]

The Epson projector EH-TW9200 does not work with hdmi input. hdmi cable is correct, I tried a lower resolution. What is the key combination for hard reset projector?Itryed reset all option on menu ,but nothing. VGA port analog has correct function.If I have motherboard Hdmi controller broken motherboard is changed along with the optics, steel that means that come paired serial numbers?
Should I'm any Epson software to change the motherboard and optics?

How I can reset only HDMI ports ?

you have to take it to epson service centre if its under warranty if not then,

If you are qualified service person,then you can open the case and see if the hdmi connectors are loose and require resoldering,if all is well then better show it to some technician you can guide you in right direction,he may even replace the motherboard only if he has similar projector which is dead for some other problems.

thanks

I have a peculiar issue with my Epson 8100. I have to switch on the projector before the AVR. The pj does not get any input if I switch on the AVR first.
Long shot but I thought it would be worth a mention.
