A 54 Furuno & ICOM screen problems

Dear Laurens,
disassembling is not that difficult. Taking the old film off is the trickiest part by far.. You get different polarized films (with/ without adhesive) easy on amazon. E.g.: https://www.amazon.com/-/de/gp/product/B0793PYDF7/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 Best regards Stefan A54 #119 Lady Charlyette, currently Panama City |

To bring this story to an (good) end:
It is possible to repair this displays with a new polarizing film. But it is tricky. Main steps: 1. disassemble the device so that the screen is freely accessible (be especially careful with small devices like VHF, which are very delicate and small) 2. remove the old polarizing film (sticks extremely well - you need a lot of patience and alcohol - to clean and remove the glue:-) 3. Important: now reassemble (without a new film!) and connect the device in order to determine the correct orientation of the new polarizing film. 4. Now disassemble the device again and mount the new foil in the correct position, then reassemble the device. Good luck and be patient! It is best (at least for the first try) to use a film without adhesive, since it is extremely difficult to remove if it is positioned incorrectly. Don't be surprised if the film does not have to be arranged at right angles to the edges of the display. With my Furuno display it was an angle of about 52° or so.

Thx a lot to all of you.
So it is the polarization film which is „burnt“ and need to be changed. I will try to get and do it. Best regards Stefan A 54 #119 Lady Charlyette, currently Aruba |

I had similar problems with the LCDs. There is no sensible repair for the display-panels themselves. You can replace them but you need to ask yourself if it is worth the trouble.
I replaced my M505 with a M506, a much nicer unit with much improved user friendliness. For the plotter you could have a look on eBay to find a replacement. In Aruba you can use eZone (https://getezone.com/locations/aruba/) to order stuff in the USA at relative good rates. I used eZone extensively when residing in Curacao and Saint Martin with almost 100% good results. The LCD are mainly affected by heat, humidity and UV, the tropics are a killer for these things. I had a Navnet 3D LCD looking horrible after years in the tropics. I replaced it with a used unit found on eBay looking much fresher and with a good display. Regards, Arno Luitjen SV Luna A54-121

I found this article on another FB site when investigating changing the MMSI number (yet to be done). It is about replacing a ICOM screen, which might give you enough information to allow you to try it on yours.

Dear Amelians,
maybe you have/ had the same on your boat - regarding the Furuno NavNet VX2 screen on the helm station and the ICOM VHF on the nav table. Both screens show something like black or significantly darker spots/ areas - on the inside of the screen glass. It seems to be related to heat (4 month on the hard in Aruba). Since this time the signs have been very clear. IMO UV light etc. can't be the cause as both devices are very protected most of the time. Do you know if it makes sense to open the devices and try to clean it or what ever? Do you know other solutions? Or is this discoloration irremovable? Thx a lot for your appreciated hints and ideas.
