DIY Lighting Repair Using LEDs - Instrument Cluster
Excellent video published by MBCluster titled "Mercedes S-Class W220 Lighting Repair / LED Upgrade" Published on 30 Aug 2012.
Summary The W220 S-Class, has an interesting lighting architecture, incorporating LEDs and fluorescent tubes to generate illumination and back-lighting on the gauges. The tubes eventually flicker and die, causing this malfunction to be a recall notice with Mercedes. Recognized for up to 10 years from MY, for registered owners, Mercedes will honor the recall, with enough coaxing. For everyone else, repair is the only option. Chinese made substitute transformers and FETs may do the trick, they may not. With this set of instruments, repair was not an option, so an experimental LED substitution was attempted, and turned out successful. An LED driver circuit replaced the 4000V transformer, retained the dimming ability, reduced current draw, and provided ample lighting. White LEDs were grafted in place of the fluorescent tubes, and blue LEDs behind the LCD displays.
DIY Missing Pixel Repair - Instrument Cluster
Excellent very detailed article by BenzWorld Member Dantus on his how he fixed his W208 2002 CLK430 Instrument Cluster which had missing pixels. Should also apply to other M-Bs including W220.
