Maliview Gauge Screen

Recommended Posts

My 2011 VLX Maliview gauge screen has gone dim, almost like the night dimming is on constantly. During the day I cannot see the screen controls.  Malibu dealer said to try installing updates, replacing the video cable and if that doesn't work, then a new screen at $2,300.  OUCH!  Any ideas?

The screens are naturally dim, that's why they have an LED backlight.  The LED backlight is prone to failure.  One LED in the string going bad will open it and kill all the light from that string.  If there's one string - no light at all.  Also, and I hate to say this because it's my particular discipline, the power supplies for these things go bad.  It's nearly always the power supply or a part of it in electronics that "breaks" them.  Typically an electrolytic cap getting to the end of it's life.  

Lets hope you're lucky.  Re-seat the plug a few times to the unit to try and clean any corrosion off and get a good circuit again.  Trying a new cable all together isn't a bad idea, but seat it several times to scrape any crud that may be on the mating pins off before giving up on that.  Lastly... has it been particularly damp and/or cold lately?  That can play havoc with electronics if any voids opened up in the potted or conformal coated electronics and normal moisture got in there and condensed.  It may very well recover after it dries out.  Eventually that scenario will cause a permanent failure though.

Otherwise, a really cheap part in the glass module is gonna stick you.  In 2011 I believe Medallion was using the industrial grade glass (and when I say glass I mean the whole module: glass, circuit board, backlight, etc) which is supposed to have a guaranteed long life production run (so that you can buy that $2300 replacement rather than have no options at all) and be significantly more rugged than whats in your average TV or white goods device.  Try the cable and cross your fingers.  See if insurance will cover it as well.  Deductible might be cheaper than that bill.
