Panasonic Y-Sustain Board TNPA5335

This specific board is designed as a direct replacement for the Panasonic TC-P55GT31. We recommend verifying your TV's model number on the back panel sticker to ensure compatibility, as circuit boards are often model-specific.

A faulty Y-Sustain board typically manifests as a complete loss of picture while the sound remains, or the presence of vertical lines or dark patches across the screen. If your TV powers on but the display remains black, this component is a likely culprit.

This is a genuine, authentic Panasonic replacement part. It is manufactured to the original specifications required to restore your television's visual performance.

Installation generally requires basic hand tools, such as a Phillips-head screwdriver, to remove the back panel and secure the board. Please ensure the television is unplugged from the power source for several minutes before beginning to allow the internal capacitors to discharge safely.

No, this board is a plug-and-play component. Once installed and properly connected, it should function immediately without the need for additional firmware updates or software calibration.
