Texas Instruments 0.47″ 4K UHD DMD Chip
This is a 100% original, brand new, Texas Instruments DLP® DMD chip. It is the exact same chip found inside many popular 4K projectors and is used as a direct drop-in replacement when the original DMD inevitably fails.
A failing DMD shows itself with a unique “starry night” effect: white pixels start appearing on the screen. Over time, these multiply into a distracting, snow-like pattern that ruins the image quality. Replacing the DMD chip with this genuine part completely restores a clean, flawless picture to your projector.
The chip is part of TI’s advanced 0.47-inch 4K UHD chipset. It has a 5.4‑µm micromirror pitch and a ±17° tilt angle, which helps produce a bright and sharp 4K UHD image (3840 x 2160 resolution).You are citing: the datasheet line “true 4K UHD resolution, 5.4-micron pitch, ±17° tilt” It is designed to work with the DLPC4420 display controller and the DLPA100 power management IC.You are citing: the product description line “together with the DLPC4420 display controller, the DLPA100 controller power and motor driver” If your main board uses those supporting chips, this is the correct DMD replacement.

Replacement Notes
This chip is a physical and electrical drop-in replacement for many older “1910-5xxx” series part numbers, including but not limited to 1910-553AB, 1910-5532B, and 1910-5537B. In fact, Texas Instruments has directly replaced these older orderables with the DLP470TE (DLP470TEAAFXJ) in their production inventory.
Important compatibility note: It is also fully compatible with a wide range of other models that use this chipset. Alternate part numbers that this chip can replace include:
- 1910-553AB, 1910-5532B, 1910-5537B
- X1910-553AB, X1910-5532B, X1910-5537B
- DLP470TEAAFXJ, DLP470TEFXJ
These chips are used in a long list of 4K projectors from brands like BenQ (UHD30, HT3550, TK850, TK800M), Optoma, JVC (LX‑NZ3, LX‑NZ3W), and Hisense laser TVs (100L5F, 120L5F).You are citing: the JasperTronics product listing line “UHD30 , HT3550, TK850, TK800M, LX-NZ3, LX-NZ3W, and the Hisense 100L5F, 120L5F”
Restore Your 4K Projector, Don’t Replace It
The DMD chip is the “engine” of a DLP projector.[reference:0] While it is extremely durable, it is also the one major component that is prone to failure over time as its microscopic mirrors will eventually seize. White dots, stuck pixels, vertical lines — these common issues are almost always a sign of a failed DMD chip, not the entire projector.[reference:1]
Replacing a DMD chip is considered an advanced repair and requires specialized tools and skills. However, for a qualified technician, it is a simple component swap that can restore a 4K projector to perfect working condition for a fraction of the cost of a new unit.
Before ordering: Please confirm the part number on your original DMD chip. If it matches one of the many numbers listed above, this is the correct replacement. If you are unsure, please send us a clear photo of your existing DMD chip, and we will verify compatibility for you personally.
