***HQ SILVER cables with VIDEO repair manual ***
Several Land Rover and Range Rover models have the common disappearing pixels on the instrument cluster (also on the board computer) - on the large LCD display that shows valuable data such as the mileage and the on board computer messages. The pixel problem lies with the ribbon cable that connects the LCD display to the circuit board of the instrument cluster. The pictures below show the instrument clsuter's LCD display before and after the ribbon cable replacement (just an example of several board computer / dashboard instrument cluster types):

Why do the Rover speedometer LCD displays fail with pixel failure? DIY Pixel repair helps with pixel failure? Well the Rover speedo manufacturers have a few minurtes only to produce a complete Rover speedo with LCD dispay and silver or carbon ribbon cable. Because of this, VDO Instrument Cluster manufacturer decied to assemble the Rover LCD display and the silver / carbon ribbon cable with heat bonding procedure. This Rover speedometer assembly design makes the contacts of the LCD display and the ribbon cable loose contact very fast, most cases in just a few years. This means, the Rover LCD display show pixel failures, it needs pixel repair, but both the silver ribbon cable and the Rover LCD display work well - only the connection of them is bad, that is why you have LCD display pixel problems, and you need a pixel fix by a professional, or done DIY with an LCD display pixel repair KIT - a silver or a carbon cable. How can we improve the quality of the LCD displays and the ribbon cables? Well if you assemble the Rover LCD with the ribbon cable with pressure, no heat bonding, then the pixels of the LCD display will work for an unlimited time. Dashboard LCD displays work on high temperature, so it is the best to avoid using the heat bonding procedure. Pixel repair DIY, or pixel fix by a professional?

No worries, this symtom can be due to a bagatel problem which can be fixed easily. If there are no pixels on the Rover instrument cluster's display at all, that MUST be due to one of the followings:
- the contacts of the Rover LCD display or the panel are not perfectly clean - this case there is no contact between the Rover LCD display and the panel of the speedometer
- either the Rover speedometer LCD display or the silver ribbon cable was mounted in the wrong direction, so the contacts are on the wrong side
- the alignment of the silver ribbon cable is not good, so the pads of the silver ribbon cable do not match the pads of the Rover LCD display or panel.
