Common TV Symptoms Fixed
A diagnosed main-board fault may cause startup failure or repeated restarting, missing picture or sound, or unresponsive inputs. These symptoms can also have other causes; confirm the faulty board before purchasing.
Fitment & Ordering Guidelines
Verify the white-sticker part number A-5077-527-A, PCB/board identifiers, full TV model suffix, and any version code on your original assembly. Model compatibility alone does not guarantee the correct board. No specific supported version codes or substitute parts are confirmed in this listing.
Disconnect the TV from power before servicing. Use ESD protection and handle the board by its edges. Internal TV components can retain dangerous voltage; installation should be performed by a qualified technician.
