1910‑50BBM / DLP470TPFQQ – 4K DMD Chip for Laser TVs & X3 Projectors
The 1910‑50BBM (DLP470TPFQQ) is a 4K DMD chip designed for laser televisions and X3 series projectors. When this chip fails, you’ll see white dots that start small and gradually multiply until the image looks like falling snow – a classic sign of a dying DMD.
If your 4K laser TV or X3 projector is showing these symptoms, replacing the DMD chip is the most effective fix. This chip restores a clean, dot‑free 4K image and gives your display a second life.
Before ordering: Confirm that your original DMD part number matches 1910‑50BBM or DLP470TPFQQ. There are many similar‑looking 4K DMD chips that are not compatible. If you’re unsure, send us a clear photo of your existing chip – we’ll verify for you.
