Thank you for your good wishes and compliment.

If I had "great skill" I wouldn't be doing this, I'd be working and earning some money hehe

On a day when I thought I wouldn't touch the Rangie I got a bit sucked in.

I wandered outside and thought the old Lexus IS250 needed a wash. It's a lovely car and was clocking 25K a year for the first couple of years I had it but down to just a couple of thousand the last 2 and it may yet be sold if SWMBO decides she doesn't want to drive the Rangie and I decide to keep it for myself.

I gave her old Jazz a wash (Ooer matron!) too and then attention turned to Nelson.

Initially I cleaned up some of the bits from the centre console that I'd removed yesterday and decided that rather then leave them hanging about to get damaged I really should put them back so I hopped in and did a bit more cleaning under in the underparts of the centre console (grim). Then I remembered that the power socket (or fag lighter to those of my generation) hadn't been working and it was still attached to the parts I was about to reinstall. A quick shufty inside the socket showed it was quite rusty in there (unsurprising with the amount of MucCoffee that seemed to have been spilled into the centre console area). I decided against trying to remove the socket from the plastic surround in case the brittle plastic broke so I retired to the garage and got a small wire brush out on the Dremel and cleaned up the inside of the socket until it was nice and shiny again.

I checked the supply and earth to the fag lighter with the meter and, once reinstalled, I tested the power socket and Bingo! it works.

Whilst sorting the centre console bits I missed having a bit of music and wondered how difficult it would be to get the radio working again. A friend who had joined me tried turning on the radio and although I'd thought it wasn't coming on he notice a feint hiss from the speakers. So, it had life but was probably locked out after having a duff battery and needed the code entering. But there was no display. We tried entering the code without the aid of a display but it clearly wasn't going to work so, after a bit of googling, armed with a pair of thick cable ties we set about removing the radio.

When we thought we had disengaged the locking pins I gave the radio a good tug (ooer) and out it popped. Only afterwards did I realise we'd pulled the bracket that the radio mounts into with the locking pins out with the radio. The mounting bracket only clips into place! very secure rofl

Once the radio was out I unclipped all of the electrical connections ...



... and began to take the outer covers off the radio

It wasn't long before I believe I found the issue:



I don't think all that gooey stuff is supposed to be there and it looks like the capacitor has leaked.

micro farad Electronics is definitely a weak area for me but i know enough to recognise a capacitor and I can read its a
volt item so looked it up on Ebay and they're about £ 1.50 (plus the usual £3.50 P&P of course). So the question is, do I stake a fiver and an hours work on trying to replace the capacitor and hope that resolves the issue (bearing in mind my rudimentary soldering skills, or do I opt for a secondhand radio cassette off ebay, or even upgrade it to something newer? (there is a 6 CD changer and a huge OEM amp in the boot BTW). I shall ponder this.

Having sat in the driver's seat and seen a few drip coming down from the headlining I had to take a look at SWMBO's discovery of Nelson's attempt to turn himself into a fish tank. After removing the driver's sun visor and the A pillar trim and top of the driver's door seal, poking about above the headlining it initially appeared that the leak might be from the sunroof drain tubs. However, after poking my head out the sunoof it was evident that the tubes were clear and further probing around found that the leak is from the top of the windscreen so, assuming we gain MOT status, the screen will have to come out and be resealed.

I'm supposed to be doing stuff other than the Rangie tomorrow but that's what I said today so we shall see.

Thanks to everyone for the good wishes and kind comments.

If you want an original P38 stereo that fits the dash properly then they're fairly pricey on Ebay, plus may not come with the code.

You could go aftermarket, and then you'll need the 2 little plastic filler panels to hide the gaps either side of it: https://www.ebay.co.uk/itm/234387633602

I would probably have a go at fixing that, given the skills you've got. Not much to lose!

Is that gooey stuff still gooey? It looks a bit like the anti vibration mastic that gets squirted on automotive PCBs to stop the larger components fatiguing their solder connections...

Thanks Norbert. Was going to buy a second hand unit but looks like they are between £120 and £250 used and around a grand new!!!!! I could put a modern unit in I suppose.

My soldering skills may need some upgrading to try and fix the original though.

Good question, so I Googled "what does a bad capacitor look like":

Did you read it though? That goo is not bad capacitor.

No I didn't, but now I have frown

Thank you for helping me to avoid wasting my time.

Anyone know a good car radio repair person near Cardiff?

Mind you, the local car group I organise meets on Wednesday so I'll ask the various members there.

It's the bulging top of the cap they're highlighting here I think.... Definitely worth having a good look for burn marks though

First things first - is the fuse at the rear of the radio ok?
Does it have12v supplies where it should? Ground(s) ok?
Is there an aerial? Does the cassette work? (may need an antique shop for that)

If you read my comments earlier I said that we can hear a faint hissing from the speakers which would suggest that the amp is working.

In order to obtain ANY output whatsoever, the code will need to be entered. I have the code and know how to enter it

There is, however, NO DISPLAY so it's nigh on impossible to put the code in.

I don't know, at this point, whether it's just the display or something deeper that's the problem.

I read online something which I had not considered which is that, being an LCD display, if the backlight fails then the readout is invisible. So, I may put it back together again (I pulled it apart again to see if I could access the backlight) and plug it in and see if I can see the display with a strong light shone onto the display (as suggested in the post i read online).

Oh, and I won't need an antique shop for a cassette. I was a DJ in the mid to late 1980's and every record I bought I put onto tape so I have bucket loads of 80's music on tape. 80'stastic!

If you do need it professionally repaired then contact Maple Audio in Bath, I've used them for car audio repairs for more than 20 years and always found them very reasonable.

Could it be the speakers themselves that are faulty? I, errm, somebody else left both front windows fully open on my van for a weekend a few years back during which we had record levels of rain. All those speakers would do would hiss whether the stereo was on or off.... When things had fully dried out they'd still hiss with the occasional crackle but they were toast.

Granted this was on a Transit with only two speakers in the doors, so quite a basic setup compared to the P38!

Appreciate the attempt to help Warren but on the basis I can't even get the display up then I think the issue runs a bit deeper than wet speakers.

What I have discovered is that shining a light into the display with the power connected and the unit turned on does not show any display letters. HOWEVER, turning the sidelights on does illuminate the radio display scratchchin

Thanks, I'll bear that in mind.

Would quite like to get it to someone local if poss for obvious reasons but could always post it I suppose.

Sounds as if an internal supply has failed or the processor is failing to start.
Have a look for dry solder joints.
Are any of the buttons stuck?
