I had the same type of problem had to replace the tdc sensor i tried to clean it but it still failed so had to replace, search on here for
Where is the tdc sensor? might be worth checking
well it took 3 weeks and 3 different garages but the sat nav is now working, they had to replace the cdrom reader in the boot and the screen came back on. At last a working car and the garage i brought the car from covered all the costs
the checker i have reads
Engine OFF Battery Check
12.5V GOOD
12.0V LOW
5.0V FLAT
ENGINE RUNNING Alternator check
15.0V High Output
14.0V Normal Output
13.5V Low Output
the screen is completly dead no faint display just like no power to the screen, i have checked all the fuses in the side of the dash ,not sure if the screen has its own fuse anywhere else.
can you explain the rest? i was going to disconnect the battery but not sure now to enter radio code it i cannot see the screen? is is difficult to remove the screen?
Hi,
The central display on my 172 has stopped working it should disply the sat nav, clock, radio but it is completly dead just stays blank.
The radio still works but no display on the main screen,
Any one got any ideas i have checked the fuses on the side of the dash and they all look good.
thanks for the info, brought a 2002 172 on Saturday and it would intermitantlyly start, taken the sensor out and rubbed a couple time on wet and dry to get the shine back now cars starts first time.:)
