Installation requires technical disassembly of the optical engine; ensure you have the necessary service documentation and skills before ordering.

Questions about this item

Does the DMD/DLP chip come with any installation hardware or do I need to buy screws and cables separately?

The listing covers the genuine OEM DMD/DLP chip only; mounting screws, flex cables or thermal pads are not included and must be sourced separately.

How do I match the chip to my Ricoh PJ WX2130, WX3340, WX4130 or WX4240 model?

The chip is tested for all four models — WX2130, WX3340, WX4130 and WX4240 — so select the one that matches the projector’s exact model label.

What does the “tested at least three times” claim mean for image quality once the chip is fitted?

Each chip undergoes three separate test cycles to confirm a clear projected image with no dead pixels before it ships.
