Texas Instruments Original DMD Chip – Model 1910C9140
This is a 100% brand new, original Texas Instruments DMD chip, identified by the part number 1910C9140. The DMD (Digital Micromirror Device) is the core imaging chip inside your DLP projector – when it fails, the resulting white dots (“starry night” effect) multiply until the image looks like falling snow. Replacing the old DMD with this genuine Texas Instruments part is the only way to restore a completely clean, dot‑free picture.
This specific part number, 1910C9140, is an older, discontinued Texas Instruments model. Due to its age, detailed technical documentation and specific compatibility lists from Texas Instruments are no longer available[reference:0]. It is a pin‑type DMD but does not belong to the widely used 0.47‑inch or 0.65‑inch 4K/1080p chip families; it is a more niche, legacy part.[reference:1]
The 1910‑series DMDs were used in various professional installation and engineering projectors from the late 2000s to early 2010s. Before ordering, you must carefully check the part number on your existing DMD. Do not assume “looks similar” will be compatible. Incorrect DMD substitution will cause the projector to fail its self‑check or display permanent image corruption (wrong colors, no display, or severe artifacts).
Part Number & Compatibility Notes

Why Your Projector’s DMD Fails – And How to Verify You Need This Chip
Each DMD chip contains millions of microscopic mirrors that flip rapidly to create an image. Over time, heat, dust accumulation, and normal wear can cause individual mirror hinges to fail, permanently locking a pixel in the “on” or “off” position. On the projection screen, this manifests as bright or dark dots that appear and multiply — the classic “starry night” effect. Once this process begins, it’s degenerative; more mirrors will eventually fail.
Replacing the DMD with this 1910C9140 chip is the only way to resolve severe pixelation and restore a perfect picture on a compatible projector.
Critical Note – Read Before Ordering
This chip is a pin‑type DMD and is not interchangeable with flat‑contact (non‑pin) DMDs. There are many physically similar DMD models (within the 1910 series and other series) that are not compatible. Using an incorrect DMD chip will not work.
Before ordering, you must visually confirm and match the part number on your original DMD chip. If you are 100% certain your chip says 1910C9140 on it, this is the correct replacement. If you are unsure, please remove your faulty DMD and send us a clear, well‑lit photo of its top surface. We will confirm compatibility for you personally.
Restore Your Projector – Not the Whole Machine
Replacing a failed DMD chip is an advanced repair requiring specialized tools and soldering skills. However, for a qualified technician, swapping this single component can bring a dead, white‑dot‑ridden projector back to perfect working order at a fraction of the cost of replacing the entire optical engine. Do not scrap a perfectly good lamp, color wheel, and DLP optics — change the one part that wears out.
Note: Texas Instruments has officially discontinued this part number and no longer provides technical support or documentation for it[reference:2]. This listing is for the physical component only — we provide no technical support for circuit integration or projector repair. If you are not an experienced electronics technician, please do not purchase this chip.
