Mercedes Instrument cluster pixel failure repair

*HQ SILVER cable with VIDEO repair manual *


Several Mercedes models, including C Class and E Class from 1995 to 2003 have fading or completely dead pixels on the instrument cluster LCD display.
This display normally shows the mileage, the temperature or the clock.

This missing pixel failure is very common at the following types:

MERCEDES-BENZ  

C Class W202 (1995-2000) : C180, C200, C220, C230, C270, C280
CLK Class W208 (1997-2009) :  CLK55 AMG, CLK200, CLK230 kompressor, CLK320, CLK430
E-Class W210 (1995-2002) : E200, E220D, E240, E280, E290TD, E300TD, E320, E420, E430

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 cluster's LCD display before and after the ribbon cable replacement (just an example of several board computer / dashboard instrument cluster types):

Why do the Mercedes speedometer LCD displays fail with pixel failure? DIY Pixel repair helps with pixel failure? Well, the Mercedes speedo manufacturers have a few minutes only to produce a complete Mercedes speedo with LCD dispay and silver or carbon ribbon cable. Because of this, VDO Instrument Cluster manufacturer decied to assemble the Mercedes LCD display and the silver / carbon ribbon cable with heat bonding procedure. This Mercedes 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 Mercedes LCD display show pixel failures, it needs pixel repair, but both the silver ribbon cable and the Mercedes 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 Mercedes 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?  


The LCD display repair ribbon cable KIT is available in silver cable and in carbon cable version. Once the Mercedes dashboard instrument cluster LCD display pixel failure was properly repaired, the Mercedes speedometer display will work as new, the silver ribbon cable and the LCD will work for good in the speedometer.


Questions-answers:

Is it really a pixel failure or just a dead bulb behind the display?

It is easy to distinguish:

- If the bulbs are out behind the display, then all the rows and colunms do work on the Mercedes instrument cluster's LCD display, but the background light of the LCD display is uneven, or some cases the display is completely dark. This case no need to repair the pixels, you do not need a silver or carbon ribbon cable, nor a new LCD display. This case you just need to buy the lightbulbs that provide light behind the Mercedes instrument cluster's LCD display.
- If the Mercedes instrument cluster's LCD display has really pixel problems, then typically lines or colunms of the display are missing. Several cases the characters are broken, numbers and letters shown on the instrument cluster's display are unreadable - the backlight is even. In case of a real pixel problem, when one or more pixels are missing from the display, you need to buy a silver ribbon cable, a carbon ribbon cable, or some cases a complete Mercedes LCD display. It really depends on that if it is a BMW, a Mercedes and Audi, VW, Saab or other make, and of course if it a MID display, a speedometer, a board computer or other LCD dipslay. Most cases, when you have a pixel failure, and you decide to repair it, it's really worth to buy a set of bulbs too, as bulbs tend to go out during repair - this is due to the massive mechanical shocks experienced during the pixel repair procedure.

Can I do the pixel repair of my Mercedes instrument cluster's LCD display at home? How about tools?

Well, most of the Mercedes LCD display pixel repair KITs we sell are designed to be simple and easy to use. The word easy should now be the subject of further discussion. An average Mercedes instrument cluster's LCD pixel repair is far more difficult then replacing a lightbulb. You definitely have to have good mechnical skills, and some household tools, such as nippers, screewdrivers, household tape, and other goodies to fix things around the house.

If you have to ask one of these questions, then you definitly should NOT do a Mercedes instrument cluster's LCD display pixel repair at home (we were asked these questions before, this is not a joke):

- Which way should I turn the screwdriver to undo the screw?
- What is a display?
- How do I find the LCD thing in Mercedes?
- How do I glue the LCD into the dashboard?
- Is it as easy as replacing a lightbulb?

Is it coming from China, or is it a high quality product coming from a proper factory?

Well, Pixelfix is an internationally registered trademark. Pixelfix only sells the highest quality Mercedes LCD display pixel repair ribbon cables, that are capable of lifetime operation. We sell most of our repairs with lifetime warranty, and you will find the exact same displays, cables, and other spare parts that we use for professional repairs. The silver ribbon cables we use for LCD display pixel repair are real silver, which is a very expensive base material, that is why the price is much higher compared to carbon ribbon cables. We also sell carbon ribbon cables, but the motivation to produce carbon cables for Mercedes dashboard instrument cluster LCD display pixel repair was only to be able to compete pricewise with the cheap chinese ribbon cables, which you may also buy for LCD dispay pixel repair on Ebay, but with a significantly worse or completely useless final result.

I replaced the silver ribbon cable of the unit, but still there is nothing on the instrument cluster display's screen:

No worries, this symptom can be due to a bagatel problem which is easy to fix. If there are no pixels on the Mercedes instrument cluster display at all, that MUST be due to one of the followings:

- the contacts of the instrument cluster display or the panel are not perfectly clean - this case there is no contact between the Mercedes display and the panel
- either the Mercedes instrument cluster 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 no good, so the pads of the silver ribbon cable do not match the pads of the Mercedes instrument cluster LCD display or the panel.
