Title: 2nd gen Jazz 2012 - Radio digital display faded, is there a fix?
Post by: Jazzmeister on July 28, 2020, 09:08:55 PM
I went and looked at a nice 2nd gen Jazz 2012, the radio display was faded. The numbers on either side of the digital display were very faint, is there any fix for this or must the whole radio be replaced?

Could it possibly be from a low battery?
The one rear window winder would only work with the car running, then the winder worked right after turning the car off again, which may mean the battery is a bit weak.

Just so we are on the same page I am referring to the digital display in the middle of the dash just above the CD slot and below the air events.
Like so:

If the display was not restored to correct function when the engine was running, I would say that that particular problem isn't battery related.

If the radio is faulty, it may be repairable, but you can buy a used, complete replacement head unit for around 30GBP over here in the UK. It certainly wouldn't put me off buying a car anyway, especially if you can use it to bash the price down further.

Even if you couldn't find one at a breaker locally, you could probably find someone on eBay that would ship internationally - I've shipped items to SA without any problems.

That's a good point about the display should be fine when the engines running if it were a low battery issue.
It's the first one I've seen with issues, the stock radio and digital display seem pretty robust on the Jazz.

My clock has the same issue with the RH digit.

Happened after a very hot day with car in sun.

As far as I know, placing in freezer for 24 hours may solve the issue with the display.
I have not bothered.

I have also seen people mention heat on another forum, I think on the Civic digital display.
Is yours also on a Jazz?

Hi, Don't know if you have resolved problem, but I wondered when you saw car, were the headlights turned on?

Reason for asking is that (also wonder if this happens with other drivers) when I turn lights on, even just side lights, the digital display above the steering wheel goes fainter (but now having to think if the radio display does the same) but is still readable.

Gonna have to double check & come back. But am certain about the 'car computer' readout above steering wheel column and also the lights/illumination around speedo & other 'dials'.

Is this the same for others?

Mines faded whether the headlights are on or off.
The behaviour you mentioned seems correct, the dimming when the headlights are on. Apparently the zeroing/dimmer knob at the cluster also affects the radio backlight.

I'm only picking up the car tomorrow but I'll post a pic of exactly what I am referring to

Likely to be one of two problems;

i) deterioration of the connection of the ribbon from the LCD. These are ususally bonded to the pcb using a special (and very expensive) conductive tape made by 3M, which conducts through point to point, but not sideways. It's very difficult to repair successfully, and requires some heat and a way of clamping the joint. Carefully clamping and re-heating the existing joint is sometimes successful. Specialist job really.

or...

ii) The polarising filter in the display has become damaged by sunlight. You can check this by holding a polarising filter sheet in front of the display, and rotate it to see if the digits magically appear. If it works, you can disassemble the unit and affix a piece of the filter to the front of the lcd display, cut at the correct rotational angle. You can buy the sheet on eBay, or a good source is scrap LCD displays from laptops - if you pull one apart, there's a polarising sheet inside.


I would go for the latter as being most likely where you are, and easier to check anyway.

The polarising filter being damaged from the sun sounds like a fair call because from googling plenty people mentioned getting the fade after very hot weather.
Could I troubleshoot using some polarised sunglasses?

Might work using the same technique, try it!

If it works, it really is like magic.

There is a fair chance that the sun in South Africa could easily damage the polarising screen. Not much chance here in Scotland. Water damage more likely.

I tried using polarized sunglasses and it didn't help, I would imagine though if the displays polarizer is damaged you may need to remove it before testing with a known good one.

It should work when you rotate a sheet of the stuff in front of the existing display. It has to be close to the lcd though, not sure if you would have any joy with the sunglasses, or if they would work at all.

Personally, I think I would just shove a good secondhand unit in.

I'll find out how expensive they are 2hnd at a breakers, how big of a job is it to swop the factory radio?

Sunglasses are horizontally polarised and if you rotate a pair of sunglasses in front of display the display should get darker and when sunglasses are 90 degrees to their normal position when you are wearing them the display will go black.... same happens when you rotate one pair of sunglasses in front of the ones you are wearing - all light will be cut out when lenses are at 90 degrees to each other.

That's more or less what happened, if the digital displays polariser was damaged should the sunglasses bring the numbers up again in the damaged areas?

It is probably the LCD display that has failed rather than the polarizing filter in front of it.  I lived in Johannesburg for 5 years and left a thermometer in the car,  it went up to over 60 degrees C ( and also had a tin of boiled sweets on rear parcel shelf melt into one solid mass ) it gets pretty hot inside a vehicle down there.

60C inside the car also happens on my driveway in Buckinghamshire.

Hasn't affected my radio display yet but not very good for dogs ;)

I always keep a thermometer in the car to show people what temperatures can reach in a modern car and how very dangerous it is to leave dogs in cars even with all the windows open.

It sounds like the lenses were doing what you would expect them to do, you should see some action on one of the edges of the clearest part when you rotate them. Probably not that then.

Possibly the ribbon cable bond, that's another part that can be permanently heat damaged.

As Culzean says, the actual liquid crystal matrix in the lcd can also be damaged by sun/heat. Not common, but can give the same fading symptoms on reversed backlit lcds (like the Jazz radio), and is unfortunately terminal.

I have noticed this extreme angle thing with other faded digital displays, I think it's the connector to the display because the numerals are darker in the morning and as the day goes it fades more.

That's probably from heat expansion increasing gap at the connector to the display and hence the resistance which then reduces the amount of current reaching that segment and resulting in it looking faded.

LCD displays are sensitive to temperature,  and the highest rated ones go up to 70 deg C...  I suspect in summer in countries like SA and Australia ( and middle east ) the temperature inside modern cars with large area of dash and sloping windscreen could exceed that.

I was up really early on a cold morning and the display was significantly less faded, almost looked "fixed" so I doubt this issue is related to the polarizer. Once a polarizer is damaged I can't see how cold temps would fix it.

As I said earlier. Perhaps the display is warping as op said it works properly viewed from an acute angle. Maybe as the cabin temperature rises.

My 2012 Jazz has the identical problem.  I live in Cape Town and when the sun gets on to the display, the clock disappears.  I can still read the radio station (It says FMR 101.3) so it’s mainly the right hand side

It’s a big mission changing the radio.  You can get a small stick-on LCD clock which looks reasonable

From looking out for it I've seen quite a few of the facelift Jazz Mk2 get faded displays, obviously a factory manufacturing defect of some sort. The MKII pre-facelift radio displays don't appear to have this issue and from my research they are compatible with the facelift Jazz.

I opened mine up in the hope it was just the LCD ribbon pins or contacts that needed cleaning and unfortunately they are all fixed/glued to the board and can't be accessed. It is quite easy to get the radio out and to open it up though and you could possibly strip the lcd assembly from a MKII pre-facelift radio and fit that so the radio still matches the black facelift dash.

Other than taking a good LCD out of another radio there is no fix. I'd go aftermarket because I see you are also in South Africa and I couldn't find a 2hnd radio from the used spares places for under R2500.

An aftermarket radio will also get you USB and Bluetooth but they aren't easy to find in South Africa if at all, you'll probably need to order one from ebay or Aliexpress?

Not to start a new topic, this idea to install a different "smart" radio unit is on my mind for years. Anyone from this forum who installed and uses it? How good is it? They will charge you 400 euro here in Ireland to do the job (job done by Ukrainians/Lithuanians, not dealers garages of course). It will be the one like from Ali, will have a direct USB for MP3 music (without adapters), a Navigation (Android! with he feature to find addresses thru Postal Indexes(codes) like GoogleMaps which I am used to), a Bluetooth, and a radio of course.

That is quite pricey for what is a relatively easy job, the radio and new fascia/surround can't be more than 200 euro incl shipping and duties if you order from Aliexpress or eBay?
Just make sure you order the correct fascia for left or right hand drive because they are different
