Backlight on LCD display of Alpine TDA-5747E car radio gone
LCD display works, ie text appears, but it does not illuminate, so cannot read at night. Back light must be broken? All other lighting behind buttons etc work.
Can that be fixed and if so, where would I take it in Melbourne Australia?

the alpine should recognize it as a "changer" when you select the source; ie: radio, CD, changer. Sounds simple, but have you turned up the volume on the iPod?
The Alpine adapter is $100, but works great, you can totally control all your iPods functions, and it displays all song info on the Alpine decks display.
I fixed my Alpine TDA-7563 with the same problem. My display was completely blank everything else worked. After checking that the LCD display is getting power and everything else in the face that I can think of, I thought maybe the rubber LCD contacts were squeezed down or something and not making proper contact, so I just pushed it back onto the board and pressed.
This was at night, so I had an external lamp and noticed to my delight that the display was in fact working, nothing is wrong with it.
I am embarrased to say that as a technician I forgot that an LCD display needs a backlight, duh.
So a simple connectivity test on the 2 lamps shows that they are both blown.
I have to source them at my local electronics store, I measured the power supply to them as 12Volts, so it is just a matter of getting ones with the right dimensions and bright enough.
Hope you have the same problem, then it will be an easy fix for you.
Yes, I'm sure Alpine will sell you another face but there is still the option of repairing the broken face at a good repair shop. Of course getting a new face is the easiest (read most expensive) way to get you going again.

Type tda into the search box and at the bottom there is the link to the manual for the TDA 7563. By all acounts they are very similar, so should get you started at least.
hope this helps :)
