DLP650NETFYE DMD Chip – Original Texas Instruments
The DLP650NETFYE is a 0.65‑inch 1080p DMD chip from Texas Instruments, used in many high‑brightness projectors and laser TVs. When this chip fails, white dots start to appear and multiply over time – eventually looking like falling snow. This is a brand new, genuine Texas Instruments DMD chip, not a refurbished pull, designed to restore your projector’s original image quality.
DLP650NETFYE is part of the DLP650NE chipset family, If your projector’s main board uses these supporting chips, this DMD is the correct replacement. It is housed in a 350‑pin CPGA package (35mm × 32.2mm) and is a through‑hole component – not a surface‑mount or flat‑contact type.

Compatible Projectors & Known Applications
The DLP650NE chipset (including DLP650NETFYE) is used in various 1080p projectors and laser TVs. Confirmed applications include:
- ViewSonic LS741HD – Service manual explicitly lists “DMD DLP650NETFYE” as the replacement part.
- BenQ i950L – Laser TV using the DLP650NE chipset.
- ViewSonic LC820 – Laser TV using the DLP650NE chipset.
- Various 1080p home cinema projectors – BenQ W1070+, W2000 series and other traditional DLP 1080p projectors use 0.65‑inch DMD chips.
If your projector uses a 0.65‑inch 1080p DMD and has a main board with DLPC4430 controller, the DLP650NETFYE is very likely the correct replacement. However, confirm your original part number before ordering – there are similar DMD models that are not compatible.
Critical Notes – Read Before Ordering
Important: DLP650NETFYE is a pin‑type (needle‑contact) through‑hole DMD with 350 pins in a CPGA package. This is not a flat‑contact (non‑pin) DMD. It is also not interchangeable with DLP650NEFYE – the “T” in the part number may indicate a specific packaging or thermal variant. Verify your original chip’s part number and physical appearance carefully.
Real‑World Signs Your DMD Is Failing
- White dots that multiply over time – Starts with a few scattered white pixels, gradually increasing into a “snow” effect.
- Black or stuck pixels – Individual pixels remain permanently off or on.
- Flickering image – Picture flickers or shows intermittent artifacts, especially at startup.
- No image despite the lamp working – Projector powers on, lamp lights, but screen stays dark (DMD self‑test failure).
- Color distortion – Affected micromirrors fail to flip correctly, causing unnatural color patches.
Restore Your Projector – Not the Whole Machine
Swapping a failed DMD chip is an advanced repair requiring proper desoldering/soldering equipment and experience with through‑hole CPGA components. However, for qualified technicians, replacing just this single chip can bring a dead projector back to full working order at a fraction of the cost of replacing the entire optical engine. Do not scrap a perfectly good light engine and color wheel – change the one part that wears out.
Before ordering: Verify your original DMD part number. If it contains “650NE” and matches the 350‑pin CPGA appearance, this chip is compatible. Send us a clear photo of your existing DMD if you are unsure – we will confirm for you.
