Hello gents. The RC backlight of my Crystalio 2 video processor does not work and it's a bit annoying in the dark. Actually, it never worked. I've got it like this, as my Crystalio 2 was a second hand purchase. Normaly, it should look like this:
On mine, only the "crystalio" logo is lit and even that it is not uniform:
Does
anyone have a clue what might be broken ? I did opened the remote and after a close inspection with a magnifier, i could not find a bad contact or so. I also cleaned it up with isopropyl alcohol and no improvement. It seems like it is drawing too much power too, because the intensity of the lighted logo decrease quite soon even with brand new batteries.

Can you post a picture of the other side of that board?

Sure. No components on the other side other than the luminiscent adhesive-film ( don't know the real name ). However, when i lifted a bit where the power comes in, i noticed that the tracks are gone. Should i solder two thin wires there ?

yeah, that does not look good. I don't know if you will be able to solder to that. Stuff may just start to melt. Another option is automotive rear defogger grid repair paint. You goop it up at the contact points with the stuff, push the film down and put something with weight on it until it dries.
Otherwise, soldering is a gamble that may ruin the film. Let us know what you try.
There may also be some type of conductive adhesive but I never really looked. But I have used the grid repair paint.

Great. Now i know what should i look for.
I'll make a visit to my car dealer and if they don't have it, the bay is a good option.
Thanks for searching that for me.

The automotive stuff is a bit more expensive and is epoxy based. Maybe take your remote with you to the dealer and maybe he or she will put a dab or 2 on there for you.  Just be sure that the grid on your remote where you put the repair stuff is not coated with something that will prevent contact. Sometimes the entire film has a clear plastic coating to protect from shorts. If it is coated you may have to scrape it lightly to the conductive material and try not to scrape that off. You can test with your meter probes set on ohms or diode scale for contact. |
