Furuno 582L lcd has become blurred and appears burned/foggy. The unit has been discontinued for years and Furuno wants $1000 for a replacement LCD however the working units value is only $450 at best. Removed the LCD and determined the LCD has a smoke color vinyl coating glued to the LCD screen which is the damaged item. Where/what could I use to replace this coating? Polarized window tint maybe??
Re: LCD coating needs to be replace or LCD REPLACED
Since you have little to loose you can attempt to remove the protective coating and not attempt to replace it with a substitute material. It's not required to operate but is intended to enhance viewing in certain light conditions. Might try a window cleaner with ammonia and a little "elbow grease". Remember though, your end result could be worse than what you have now if you're unable to completely remove the film or damage the JCD panel in the process.

You need to determine if it's moisture or damage to the protective coating on the LCD glass. If the screen coating is damaged it will have patches or discoloration that resemble water spots like you see on windows and glasses exposed to hard water. If it's moisture between the glass and LCD you should be able to make out the tiny water droplets that are evenly spread throughout the screen. The only proper fix for a glass with damage to the protective coating is replacement of the bezel assembly. If it's moisture you can try inserting a few silica gel packs inside the unit. Don't try to disassemble the bezel (LCD/Screen) assembly. Just but the gel packs inside the 1650 chassis and give it a day or two. Otherwise, you're looking at factory repaire.
christian204, Your unit may be 5 -6 years old, and may have developed a problem with it's internal "switch-mode-power-supply" and will need good CCFL backlit lcd monitor tech to repair it. When strange and wierd things start to occur on lcd screens the first place to look would be the SMPS. 12fixlouie
First off it could be the backlight bulb or the LCD inverter. I would try the LCD inverter first it will cost about $25 and is easy to get to Take the face plate off around the monitor and the LCD inverter is at the bottom. It looks like a strip of circut board with plastic coating over it. Most of the time it is the LCD inverter.
But if its the Backlight bulb you might be able to take it to a local tv repair shop. you can order the backlight bulbs online but they are gragile and tricky to replace. you have to seperate the layers of glass on the screen abd the backlight will be at the top inbetween the layers of glass. If you do decide to do make sure to wear rubber gloves because the oiles from your fingers will get inbetween the glass layers and cause foggy spots when you put it back together.
you need an MB1100 matching box
has the 10 pin pigtail for your sounder and accepts bare wire input from your ducer
this will also ensure that all power from sonar get to ducer, but it from me if you like
