Ruth's sister Internal Power Cable for PSR S500 S550 S650 S670 DGX-520 DGX-620 DGX-630 DGX-640 DGX-650 mm6 mm8

SKU CH-15Z3-MVGE5

An internal power cable compatible with multiple Yamaha keyboard models

  • Replacement screen fits PSR-S500, S550, S650, S670 models
  • Compatible with DGX-520, DGX-620, DGX-630, DGX-640, DGX-650 keyboards
  • Works with mm6 and mm8 synthesizer modules
  • TFT panel technology provides clear display output

Compatible LCD Panel

This replacement LCD panel fits a wide range of Yamaha portable keyboards including the PSR S500, S550, S650, S670 and the DGX series models 520, 620, 630, 640 and 650. It also supports the mm6 and mm8 instruments. The component is a TFT type display sourced from Mainland China and listed as new condition. It restores the visual interface on compatible arranger workstations and portable grand pianos.

Replaces Damaged Original Display

The panel serves as a direct swap for a cracked, dim or non-functional factory screen on the listed models. The upgrade is worth it when the existing display shows dead lines, backlight failure or physical damage that prevents menu navigation. Installation returns full visibility for voice selection, style browsing and parameter editing without requiring a mainboard change.

TFT Screen for Listed Keyboards

The display comfortably handles the graphical menu systems and notation view used across the supported PSR and DGX product lines. It runs out when a keyboard model falls outside the specific series names and numbers provided in the compatibility list. Buyers needing a screen for other Yamaha series or different manufacturers should verify fitment before purchase.

Questions about this item

What physical space does the cable need inside the PSR S500?

The internal power cable fits the existing connector routing in the PSR S500, S550, S650, S670 and DGX 520, 620, 630, 640, 650, mm6 and mm8 keyboards.

How is the cable installed and which step is often missed?

Disconnect the keyboard from mains power, open the chassis, unplug the old cable from the main board and display inverter, then route the new cable through the same clips before securing both connectors.

When will this cable need replacement?

Replace the cable if the display flickers, shows artefacts or loses power intermittently, or when servicing the TFT panel in any of the listed models.
