Genuine Dell 17" LCD Ribbon Cable

This genuine Dell OEM ribbon cable carries the Dell part number DY656 and is built as a direct replacement for the display interconnect in specific Dell laptops. It is intended for owners of a Vostro 1700, Inspiron 1720 or Inspiron 1721 who need to restore the video link between the motherboard and the 17-inch LCD panel.

Verify your exact model before ordering

Confirm that your laptop is a Dell Vostro 1700, Inspiron 1720 or Inspiron 1721 with a 17-inch screen. The cable is not compatible with other Dell series, different screen sizes or models outside the three listed. Match the part number DY656 to your service manual to avoid a mismatch.

Designed for continuous panel operation

Once installed the cable maintains a stable video signal for as long as the laptop remains powered on. It is engineered to handle the constant flex and thermal cycles of daily lid movement without signal degradation. This part does not add external video outputs or support multi-monitor setups beyond the internal display.

Questions about this item

Does the Dell DY656 ribbon cable arrive with any brackets, screws or adhesive strips, or must those be sourced separately?

Only the 17" LCD ribbon cable itself is included; no brackets, screws or adhesive strips are supplied.

The cable is listed for the Vostro 1700, Inspiron 1720 and Inspiron 1721 — how do I confirm which one matches my machine?

Check the service tag on the bottom of the laptop or the model label inside the battery bay; the part number DY656 fits all three models listed.

What does the 17-inch figure mean when the cable is fitted inside the laptop?

It identifies the screen diagonal the cable was designed for, ensuring the conductor length and connector pitch match the 17" panel used in the Vostro 1700, Inspiron 1720 and 1721.
