Dell 4210X DLP projector bulb has some i2C sensor or chip?

Hello good fellas!

I ran into a problem and thought maybe some people here in diyaudio have experience on that hand to share.

So I was retrofitting an Dell 4210X projector (I got it without an bulb module) to work with a LED. I guess I did bypass the lamp ballast already, tried different pins also just in case. So next I was looking at some strange board I found in the lamp module hole. It reads "LAMP TRANSFERRING BOARD". There are 4 pins that read GND, SCL, SDA and 5VSBY (standby?). There is no components and wires run back to mainboard.

The board looks like this:

So my fair guess it, that basically, it seems that the lamp module as some sort of a chip that is connected to the mainboard via i2C interface. Maybe it's temperature sensor? Not so likely as there is one already. Probably a chip that stores hours that the lamp has worked? So when lamp is changed the counter is reset.

Now, buying a lamp is expensive and I would not like to go that way. It would be great if I had a broken lamp or even just the chip to probe it and somehow bypass that also.

Does anyone have experience with that lamp chip?
Could you please help me bypass it?

Thank you!
