Radio and HVAC screen

MDK · Post by **MDK** » 26 Jun 2018, 11:42

Hey all..MDK here. I just bought a 2005 V50 T5 and the screen for the radio .. well the bottom part is black.. you can see the top half so I guess the screen is cooked. I went to the scrap yard today and I pulled one from a 2004 S40 T5. Everything plugged in but didn't come on. So do you guys think it's a mating to the car thing? A dealer programming thing? Or should I pull another one...any comments will be appreciated... thanks

Mating/programming issue? Probably (near certainly).

Bottom part of the screen not working could be something as simple as an internal loose ribbon cable or a backlight LED(s) out. If it were me I'd be disassembling both and transferring the LCD display elements from the new one while keeping the main circuit board(s) from the original which would be the parts containing software that is specific/matched to the vehicle.

THANKS Mr Brian . I'll give that a try. I'll keep you all posted as to what I come up with...MDK .. rolling on!

Hey Mr Brian... I have the vida/dice 2014 D with a Dell 4G laptop built exclusively for the Volvo's... could I program / update that new radio screen with it? ... I'm a pretty good mechanic... when it comes to computers... I might as well be living in the 70's I actually hate computerized anything....rah !!they're evil

Performing a software reload to the used module would require a 3-day subscription at the least ($$$) to do it yourself... if I'm not mistaken.
The best way to get around this is to keep the parts that are mated/programmed to the car (main circuit board) and just repair/replace the screen as already mentioned.

Any cell phone/laptop repair outfit with techs that can replace phone/laptop screen would probably roll their eyes at this relatively 'easy peasy' little job compared to what they're accustomed to working with.

Be aware I have not ever taken one of these apart: you'll need to be highly observant during disassembly. There are several ways the screen might be attached/connected to the board (plugs that snap into a socket or slide onto rows of pins, flat cables can be secured by either a flip-latch mechanism or individual wires soldered through holes etc). I'm not sure exactly what you'll find inside there aside from no less than one circuit board and the LCD screen in question.

Yeah I hear you mrbrian... If it's not at least a 500$ repair... it's not a Volvo. Sheesh. Anyway, this is what I did. I disassembled both units and swapped the screen out. As I took it apart it had a crack in it ... now I just got done assembling and re installed it in my car and working good. I figured all the programming would be in the circuit board. I bought the one from the junk yard for 10$ .. I'm sure Volvo would have charged considerably more...

Not sure how to do the arrow thing yet but mission accomplished..

What you did is considered a component or 'board level' repair. ASE techs aren't trained to do this type of work as a general rule. The rule they follow is 'if an electronic module doesn't work right, replace the whole thing'. So no, a dealer (and the vast majority of independent shops) aren't going to do what you did - so yes, I'd say at least $500.

BTW: Thank you for reporting back

Many people ghost once the car is fixed and leave us hanging/wondering whether our advice/recommendations worked or not.

I hear you about the "ghost" thing. I'm pretty new to the form But I spent 3 yes watching an old man who had an independent shop. He actually started with Volvo in 1975 . Old Tom is a biker . He repaired Volvo's exclusively but could fix just about anything that came in the shop. I have a slight advantage myself as I use to assemble electronics for the military. So, I try to advise the people here from what Tom taught me. We fixed alot of Volvo's....MDK rolling on
