Replacement LCD Kit for Autohelm Raymarine ST5000+ Control Head A12015

Restore the display in your Raymarine, Raytheon or Autohelm ST5000+ autopilot control head with this new aftermarket replacement LCD kit. It is designed to replace a faded, darkened, damaged or partially unreadable original screen while retaining your existing control head.

This listing is for the replacement LCD and conductive connector strips only. It is not a complete autopilot control head or autopilot system.

𝗣𝗮𝗿𝘁 𝗡𝘂𝗺𝗯𝗲𝗿 𝗜𝗻𝗳𝗼𝗿𝗺𝗮𝘁𝗶𝗼𝗻

• A12015 identifies the complete ST5000 Plus SailPilot kit; it is not the individual LCD part number.  
• Q220 is an early Raymarine display-kit reference used with Plus-series pilot control heads.  
• A18012 and A18012-P identify the later Raymarine Universal Pilot Display Kit used with several related Plus-series control heads.  
• The original factory display kits included additional parts such as labels, window inserts and an LCD surround.  
• This aftermarket listing supplies only the LCD and two conductive strips and should not be represented as a complete genuine Q220 or A18012 kit.

𝗥𝗲𝗹𝗮𝘁𝗲𝗱 𝗦𝗧𝟱𝟬𝟬𝟬+ 𝗦𝘆𝘀𝘁𝗲𝗺 𝗥𝗲𝗳𝗲𝗿𝗲𝗻𝗰𝗲𝘀

Raymarine catalog information identifies the following complete systems within the ST5000 Plus family:

• A12010 – ST5000 Plus hydraulic rudder kit  
• A12011 – ST5000 Plus hydraulic outboard kit  
• A12012 – ST5000 Plus sterndrive system, 1993 configuration  
• A12013 – ST5000 Plus sterndrive system, 1995 configuration  
• A12015 – ST5000 Plus SailPilot kit  

These numbers identify complete autopilot systems rather than LCD screens. Before purchasing for any application other than A12015, verify that the installed controller is marked ST5000+ and compare its original LCD segment arrangement, dimensions and contact locations with the listing photographs.

𝗖𝗼𝗺𝗽𝗮𝘁𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝗥𝗲𝗾𝘂𝗶𝗿𝗲𝗺𝗲𝗻𝘁𝘀

The replacement should be selected by the control-head model and screen configuration—not by the boat’s manufacturer, length, year or steering system.

Confirm all of the following before ordering:

• The controller is marked ST5000+  
• The original screen has the same segment arrangement  
• The LCD dimensions match  
• The conductive-strip locations match  
• The internal surround and contact-pad arrangement match the listing photographs  

𝗡𝗼𝘁 𝗖𝗼𝗻𝗳𝗶𝗿𝗺𝗲𝗱 𝗙𝗼𝗿

• ST5000 controllers without the plus symbol  
• ST4000 or ST4000+ control heads  
• ST6000, ST6001 or ST6002 control heads  
• ST7000 or ST8000-series controllers  
• ST1000+ or ST2000+ tiller pilots  
• Modern p70, p70s, p70R or Evolution-series controllers  
• Multifunction chartplotters or standalone marine instruments  

Some Plus-series controllers share related service components, but this does not guarantee that their individual LCD screens are interchangeable. Match the original screen before purchasing.

𝗦𝘆𝗺𝗽𝘁𝗼𝗺𝘀 𝗧𝗵𝗶𝘀 𝗞𝗶𝘁 𝗠𝗮𝘆 𝗖𝗼𝗿𝗿𝗲𝗰𝘁

• Missing or incomplete LCD segments  
• Faded or low-contrast information  
• Darkened or sun-damaged screen  
• Blotched, leaking or physically damaged LCD  
• Intermittent segments caused by deteriorated conductive strips  
• Display information visible only from certain viewing angles  

𝗧𝗵𝗶𝘀 𝗞𝗶𝘁 𝗪𝗶𝗹𝗹 𝗡𝗼𝘁 𝗥𝗲𝗽𝗮𝗶𝗿

• A control head that does not power on  
• Failed display backlighting  
• Damaged diffuser or reflector components  
• Circuit-board, processor or power-supply faults  
• Internal corrosion or water damage  
• Faulty keypad buttons  
• SeaTalk or NMEA communication faults  
• Fluxgate compass or rudder-reference faults  
• Steering-drive, hydraulic-pump or course-computer problems  

A completely blank display may be caused by a power, backlight or circuit-board failure rather than the LCD itself. Diagnose the control head before ordering.

𝗜𝗻𝘀𝘁𝗮𝗹𝗹𝗮𝘁𝗶𝗼𝗻 𝗡𝗼𝘁𝗲𝘀

Disconnect vessel power before removing or opening the control head. Carefully document the position and orientation of the original LCD, conductive strips, surround, diffuser and reflector during disassembly.

Clean the circuit-board contact pads using a suitable electronics-safe method without scratching or damaging them. Position both conductive strips evenly and reassemble the housing gradually so pressure is distributed across the screen.

Inspect the case seal and bulkhead gasket before reinstalling the controller. Damaged seals should be replaced to help prevent moisture from entering the unit.

The LCD is fragile. Professional installation is recommended if you are unfamiliar with electronic instrument repair.

𝗣𝗮𝗰𝗸𝗮𝗴𝗲 𝗖𝗼𝗻𝘁𝗲𝗻𝘁𝘀

• 1 replacement LCD screen  
• 2 conductive elastomer connector strips  

𝗡𝗼𝘁 𝗜𝗻𝗰𝗹𝘂𝗱𝗲𝗱

• Complete ST5000+ control head  
• Autopilot course computer or steering drive  
• Hydraulic pump or SailPilot drive components  
• Keypad, fascia or sun cover  
• LCD window, surround, diffuser or reflector  
• Case seal or bulkhead gasket  
• Wiring, compass, rudder sensor or mounting hardware  

𝗕𝗲𝗳𝗼𝗿𝗲 𝗢𝗿𝗱𝗲𝗿𝗶𝗻𝗴

Compare the original LCD and control-head markings carefully with the listing photographs. Do not rely solely on A12015, since that number identifies a complete SailPilot system rather than the individual screen.
