No. I kept the ribbon cable attached and just tightened the torx screws. Just tight enough so I wont' strip out the plastic mounts.

only thing you did was to tighten the screws back of the HU, does it really help to get the HU show perfect digits?

koich

Yes. All I did was tighten. It's really a quick job. Just tightened the 6 or 7 torx screws and that was it. They all turned about 1/4 to 1/2 a turn and that made a huge difference.

If you're doubtful, just give it a shot. Worst case scenario is it stays the same.

KJI3jflarryfe93

if these are plastic torx screws maybe should be careful not overtightening and messing them up?

let us know if you get iffy digits for the next few days
many thanks for the info

koich

The screws themselves are metal. But the base is the plastic display frame, so I would be careful when tightening. Did might tight, but not to the point where it would strip.

I'll keep you posted. The weather here is rainy now, so generally I think the temperature is a little up, but will keep an eye on it.

KJI3jflarryfe93

this might be a cheap solution to tighten the screws and not having to buy an expensive replacement unit.

i wish you good luck with your display it will work now.
i will try this next spring when i take my car out from her winter beauty sleep

koich

Just an update. Climate control is working fine. The display is fully working.

KJI3jflarryfe93

do you stare at your lcd display all the time while you're drivin?
it's great it worked out for you, I will try to tighten the bolt when I have the time.
thanks

KJI3jflarryfe93

what's going on with your lcd?
is it still in shape without pixle problems after you fixed it?

It is starting to do the disappearing act again, time to take it apart again...

KJI3jflarryfe93

all this time after you fixed the lcd, did the display work perfectly?
maybe your suspension is to stiff and bouncy giving your panel a hard time?

maybe this shop sells ribbons for lcd?

My LCD is getting blotchy again. Time to take it apart....

I would just call this company in the UK and see if they can send a replacement ribbon. Makes more sense to me to replace than just doing a temporary fix and having to take the unit apart several times to fix it.

koich

Yeah, mine is all screwed up again....

Same issue with the fading numbers. I just ordered a climate unit off ebay for $50 shipped. Didn't see this thread though...

Is the quick fix working? Maybe some electric grease on the connections and locktite on those threads would hold it in better.

Mine does it when I switch off the auto A/C

KJI3jflarryfe93

hey mickey
if you bought a used one off ebay you're likely screwed, this HU looks good and works while junkman strips the car in parts but the problem mostly occurs when you drive the car, then you will notice if it's good or bad from vibrations when you drive!
we will all eventually suffer from these inferior quality head units!
buying a new one for high price at stealership is the only way to go if you can't find a cheaper vendor?

mickey13

I dont like to be screwed unless its by a skinny blonde swedish, dutch or german. wait...mb is german right????

KJI3jflarryfe93

swedish blondes are known for the swedish sin back in the 70's, still the same behaviour from them today
there are no limits in the sack from them

Climate Control Unit came in the mail a couple of days ago, $50 shipped. Popped it in and works beautifully. Let's keep our fingers crossed. I guess I'll play with the old unit when I have some time.

mickey13

OK so the new unit doesn't have an issue with the LCD, but the backlight is flashy. I'm going to pull it out and replace the bulb (think I read somewhere I can do that), but otherwise works fine. I can probably just use the bulb from the unit with the bad LCD/wire.

KJI3jflarryfe93

yeah, you can replace bulb, no problemo

fading lcd shows from vibrations, maybe you got your self a good unit?

DRBC43AMG

Check the connection to the bulb first. Could be the plug, but keep a spare bulb around.
