[pinky77]

today just fitted the av lead to the white plug on tv tuner then connected a dvd via av leads then turned unit on av but no sound or pic sat nav ok and radio ok but no tv seems to search ok ive checked all connections inc aerial leads all good any ideas please

[Sanj]

Confirmed that the DVD player is working?

The leads used, are they phono both ends or jack one side to 3 phono on the other?

the leads are the same i used 1 video (yellow) and 1 audio (red) i looked on the back of the head unit its got 2 plugs 12 pins on both connected but theres a small plug on loom and dont seem to go anyware

The small plug on the loom sounds like the aux extension. You need the aux extension lead from the dealer to plug into this.
One of these:



and i've added the pins/connections for both plugs on the tv module for you to check against

i taken the tv tuner out today to find it corroded at the bottom especially where the aerial leads are (water damage) im thinking this is main prob im tempted to get another analog tuner cheepish as digi bloody expensive and fit freeview and see if i can get this to work

fitted tv tuner in today and got pictures but very little sound just hear it when i turn vol fully up and same on cd player i fitted radio and sat nav all good confused on this one ??

Did you refit the damaged tuner or a new one? Perhaps there is some damage to the wiring that feeds both the tv tuner and the cd player given the corrosion that you found on the tuner. Have you checked the connections at the rear of the CD player? I'd take the CD player out and clean the connections well and refit. The tuner as you said, may well now be faulty with the corrosion - did you manage to clean it up completely and spray with electrical contact spray (NOT WD40)?

hi condor fitted another tv tuner that was tested ok. binned the old one wireing seems good im wodering if the tvtuner got wet did the radio tuner as well ?? as i think the tv goes through the radio tuner for the sound ..cd plyer plugsconnections ok with this no sound whatsoever the tv if i wind the vol well up i get a little but not enough to hear good ive been mechanic 40 yrs m8 but when i seen in the boot of the x5 the wireing looks like a behind dash of a aircraft bloody complicated to me

Maybe theres a problem with the dreaded BM54 module or whatever its called - Sanj and others know more about this fault than I do, and I think Jason from Chiptune who is on this forum offers a repair service for it..... sounds like one of these dry joint problems or whatever it is that the pc board of the radio module suffers from..... perhaps a PM to Jason ???
