Need help! Ford 6000 CD radio blown ?

[m3mpower]

Hi
I hope someone can help
I have a Ford 6000 CD radio / CD player, i connected to the battery but i wasn't paying attention and i connected the + and - the other way around and within 2 seconds there was a bit of smoke, i disconnected and reconnected the right way but now the radio does not power ON !
There is no fuse at the back of the radio!
I removed the PCB and i can see there is a "cracked" IC ?
Anyway, i would appreciate is someone could help to bring this radio back to life!
What should i replace ?

Thanks in advance

It has reference:
420 2BA
Not sure what this part is and where it can be bought...
Any ideas?

Thanks

hi its just a power diode
cpc or farnell or maplin ebay

Hi
Thanks for your help

I have a damaged RCD200 and i looked on the PCB and found a similar diode, exact same size but different numbers, i guess i can use this..?

Hi
I have replaced the power diode and the radio still does not power up !

I have checked with a multimeter while the radio is connected to the battery and there is power coming to the diode

Any other ideas please?

Thanks

[willywonker2010]

dont forget u need both lives
and both earths
for radio to power up
earth x2
ign 12+
batt 12+

It looks like a quadlock connector so you should only need 2 x earth and 1 x live for this radio. Either way, check if you have supply voltage to MCU. Also check voltage to on/off button. Whats the exact part number for the radio.

Hi
Yes i know, i have a pre-made connector for Ford radios..

Any ideas how to fix this?

thanks

Hi
Willywonker2010 is right, it needs 2 earths and 2 lives, but it is still not powering..

The model number is Ford 6000 CD, Visteon PWB14672, VP6S6F-14A608-CH

i have checked the voltage to power diode and most fuses and they seem to be OK..

How do i check MCU and power button ?

thanks

[Dunker]

Voltage meter on the 2 pins that short when power button is pressed. Usually one is earth and other is 5 volts. 5 volts will drop to zero when button pressed. Also find 5 (or maybe 3.3) volt feed to MCU - there will be a reservoir capacitor near it. I suppose you can check voltage to MCU xtal - use a digital voltmeter. Usually 2 to 2.5 volts (its a sine wave but a digital voltmeter will give you a clue if its oscillating.

Hi
Thanks again for your help
I don't have much experience with these boards so could you please show me where the 2 pins are on the board for the ON/OFF button?
And where to check voltage to MCU?
I do have a digital multimeter
This is the photo of the board

Thanks very much

m8 the diode which has blown provides protection to the pcb, what happens if there is a short,this diode will blow and cause a short which then will blow fuse in the vehicle, so i would check you fuses and your power feeds first.


dont forget to press thanks

Hi
The radio was not connected in the vehicle, it was connected on a bench...
So something is not right in the PCB and not on the vehicle

Thanks

Hi
Any other help guys?? i'm still trying to fix this..
Does anyone know what to do please ?

Thanks

ON TOPIC:-

a long long long time ago had a car in, the bloke was a vicar, his radio was dead.

Was unable to see why it was dead, so told him it was ~~~~ed and sold him a new one, buggered if could find the fault - the only thing on the board was a piece of foam rubber ripped it off, and there laughing was a blown track.

Also, as you have the board out it might use the case as a 'link wire'

if possable can you 'join' the case solder points to neg or put back in the case.

as a rule the diode is across the suplly rather than in series WHY? - so in theroy everything should be ok.

Now it might be worth looking around the processe area, look for capacitors and chips with 3/4/5/6 legs use google the numbers on them untill you get regulator then use the datasheet to test for power.

OFF TOPIC & AGAINST DK RULES:-

Will send a PM to a DK member who skanked a ford radio off me, see if he can sell you it.

(that will pay my hotel bill for my next vacation!)

HTH

Meat.

Hi everyone
I have looked at this stereo again today, after giving up for a few weeks!!
I have compared the circuit board with a "working" headunit..
While connected to power, i have tested every fuse and every capacitor...
Here are the differences between the working headunit and the non working one:
On the faulty one, there are 2 capacitors and 1 fuse and 2 main points that are showing 0 volts
On the working one, these are live +
Please look at the photos below
Do you think if i change the capacitors the headunit will work?
( yes i guess i can try but i need some advice...)

Thanks in advance

just strap a bit of wire to the 'live' (dead) point, join to power - stand back.

sounds like it a multilayer board and something internal has a blown track.

Would be worth folling each 'dead' track back see where it goes.

Should i change the capacitors circled in red in my previous photo?
Or, should i somehow test them ?

Thanks mate

Should i change the capacitors circled in red in my previous photo?

Under the circumstances, i would just solder a wire to the big capacitor - the positive one.

End of day on face value it had for a split second bacwards charge up it's arse.

would be more conerened about the amplfier chip being fried.

Use your other radio - figure out if that capacitor is B+ or IGN fed - conneect it to which ever, stick the lid on, then mix some concrete up, seal it good, let the concrete go hard for 24 hrs - then try it if it works great, if it don't it's ~~~~ed, you need an new one.

OK, so i should solder a wire to the big capacitor and/or run a + wire to the power point ..? what if the radio works then, what does it mean?
Sorry about all these questions but i want to save this radio, it'll be a shame to throw away !!

1) If you had a telly that was in the river for 6 months - would you try
and repair it, or chuck it.

2) The working radio - plug it in the car, jab your favorite voltmeter on the POSITIVE side of the capacitor - take note of the reading

3) Turn ignition on - see if it changes.

4) *GUESS* it will be live all the time - which ever, solder a wire onto it - dremal the case if you have to and connect to B+

if it works job done, if it don't

a) solder links here there and every where to that pos

b) Stick on ebay - as 'un tested'

Hi
Can it be a faulty semiconductor? the Multiple voltage regulator NXP70966FB? i have looked at the board and i can see the + of the big capacitor is connected to this part ( it is the IC that looks like the amplifier IC ), and then also this NXP IC is connected to the rest of the fuses....etc
I have searched on google for a seller but can't find this part, found a link where it says the equivalent could be TDA3683J .

Has anyone ever fixed this kind of problem ??
Here is a photo
Thanks

think the best thing you can do - although against DK rules is ask if anybody has one that is "13 locked" for sale.

rob the bits to your hearts content.

Just going to send a DK member a PM - no user names - that MIGHT have one of them for sale - with history :roflmao::roflmao::roflmao:

Here is what i found out today about that semiconductor:
