Replacement Touch Screen Cable for Studio 1749

This cable replaces the touch-screen flex assembly in a Dell Studio 1749 notebook with a 17.3" touch display. It carries the digitiser signals between the panel and the mainboard. The part is not the main LCD video ribbon and will not work on non-touch variants of the same chassis.

Dell Part Number D655T Fit and Finish

The component is a genuine Dell OEM piece identified by part number D655T and listed as a working pull in excellent condition. Its connector layout matches the factory routing inside the Studio 1749 hinge area, so installation follows the original service manual steps without adapter cables or pin-out changes.

Low-Power Signal Link in Daily Use

The flex carries only low-voltage digitiser data, so it adds no measurable heat or audible noise to the system. Power draw is negligible compared with the display backlight or GPU, and normal laptop operation remains thermally unchanged after the cable is fitted.
