New 4K UHD DLP DMD Chip for BenQ TK700STi Projectors – DLP471TE
If your BenQ TK700STi 4K gaming projector has started showing white dots that slowly multiply until the image looks like falling snow, the DMD chip is almost certainly failing. This Texas Instruments DLP471TE DMD chip is the heart of your projector’s display system – a genuine replacement that restores a clean, dot-free 4K picture and brings your high-performance gaming projector back to life.
This is not a refurbished pull from another machine. It is a brand new, genuine component manufactured to original specifications, designed to restore your BenQ TK700STi to its original image quality and performance.
The 0.47-inch DLP471TE is a digitally controlled Micro-Electro-Mechanical System (MEMS) spatial light modulator (SLM) that enables bright 4K UHD display systems. It is a core component of TI’s 0.47-inch 4K UHD chipset, which must always be paired with the DLPC7540 display controller and DLPA100 power management IC for reliable operation.
Typical applications using the DLP471TE include laser TVs and enterprise projectors.

Real‑world Signs Your DLP471TE DMD Chip Is Failing
- White dots that multiply over time – The classic “starry night” effect. Starts with a few scattered white pixels, and they gradually increase until the image looks like falling snow.[reference:5]
- Black or stuck pixels – Individual pixels remain black or permanently “on,” creating a distracting pattern on the screen.
- Flickering image – The picture may flicker or show intermittent artifacts, especially at the beginning of a session.
- No image despite the lamp working – The projector powers on, the lamp lights, but the screen stays dark – the DMD has failed its self-check.
- Color distortion or missing colors – Affected DMD pixels may fail to flip correctly, causing tint shifts or unnatural color patches.
These failures are often caused by thermal stress, prolonged use in high-temperature environments, or simply age-related wear of the microscopic mirror hinges. Replacing the old DMD chip with this genuine Texas Instruments DLP471TE is the only effective solution to restore a clean, stable, dot-free 4K picture.
Restore Your BenQ TK700STi – Not the Whole Projector
When a DMD chip fails, the symptoms can mimic a full optical engine failure. However, replacing just this single component is often the only repair needed to restore complete functionality. If you have already ruled out the lamp, power supply, and main board, the DMD chip is the prime suspect. Replacing it with this genuine Texas Instruments DLP471TE part ensures compatibility, reliability, and long service life. Don’t scrap a perfectly good DLP optical engine, color wheel, and lamp – just change the one part that wears out. Bring your 4K gaming projector back to life and get back to low-lag gaming and movie nights.
Note: This is a genuine Texas Instruments DLP471TE DMD chip, manufactured to original specifications. We strongly recommend verifying your existing chip part number before ordering. Send us a photo of your existing DMD if you need confirmation of compatibility.
