After you recover from that, you might check or have your mechanic check all the connections to it and especially the ground connectors for the dash.
Leading evidence: 'Check connections' (no explicit attributable resolution; this is a reported action or suggestion).

If that doesn't work, then a plan B would be to check the connections, etc.

The guy who said disconnect the fuse and let it sit for 10 minutes is a genius!

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I recently purchased a used 2005
Boxster S
, which after investigation I am pretty sure has
PCM
2.1 (with
Bose
)
After only one week of ownership I got into the car, turned on the ignition and the screen lit up in a very strange and garbled way (lines and general messy looking appearance) and then went black.
There is a backlight on, however the screen is black and has various 'lines' going vertically. Radio and music and CD changer works just fine, however I can't see anything on the screen, so it's pretty disturbing.
Any ideas as to what may have gone wrong?
Thanks!
Hmm being an 05 +4 yrs of warranty that's 09! I hope the car is still under warranty!! if so, take it to the dealer... if not, take it anyway
and they should be able to tell you and give you a quote.
Hmmm... You could follow Alfred's advice. I'm thinking they'll tell you you need a new unit for $2K or something.
After you recover from that, you might check or have your mechanic check all the connections to it and especially the ground connectors for the dash. Lots of scary problems can be solved with something simple if you just poke around and look for things wrong. I've seen a lot of odd things occur when the ground straps corrode on cars about this age. I'm not sure where these are on Boxsters and
Caymans
yet...I'm still new to the breed, but I'm sure I'd check for that and for loose connections before spending the big bucks on a new
PCM
..
..and before I'd let the dealer replace it, I'd buy one off one of the members here or from a reputable boneyard and either replace it myself or have a good non-dealer mechanic do it. So far as I know, it's not typical for these to fail, so I'm thinking it's a connection somewhere.

sixisenuff is right, you can check the connections. Here's the link to Ken's article on how to remove the
PCM
unit.
PCM 2.1 Install (CDR-24 Radio Removal) - My Articles
First thing, look through some of the posts here in the electronics form and determine which fuses run the
Bose
and
PCM
systems - pull them and let the system reset for about 10 minutes...
plug
them back in and see if this changes things - this seems to have fixed many
PCM
/non-CM
Bose
problems - especially then ones where ASDS (audio sudden death syndrome) appears. If that doesn't work, then a plan B would be to check the connections, etc. as described by the other posters.

Well.....I am sitting at the dealership drinking their free coffee (I'm assuming nothing else here is in that category) while they "check it out". Based on my description of the issue, without seeing it they jumped immediately to the "the LCD is probably blown" conclusion. So, I will wait to see what the tech says when he actually looks at the car.
Thanks for all the posts so far...I will absolutely be trying out these 'quick fixes' before dropping serious $ on a new system.
Maybe I will just live with the lack of screen and NAV for a while if it proves to be a dead LCD screen....I can still listen to all my music, which really is my main focus in the car. To be honest the
PCM
NAV is pretty crummy having used
Garmin
's and Tom Tom in the past. The
PCM
is pretty, but not as good as the others...IMO.
I'll let you know the outcome!

Good luck. You're starting in the right place. I'm sure they'll try and suck you wallet dry. They don't get as much money from
Porsche
as they get from you for a repair, so they always try to squirm out of a warranty issue. I doubt that the
PCM
is "blown", but if they want to put a new one in for free, I'd definitely let them.
The guy who said disconnect the fuse and let it sit for 10 minutes is a genius!
The point of my post was "Always try the simple stuff first." and "If there is a chance of a mechanical failure in an electronic system, it's likely that the mechanical item (connection, switch, fuse etc.) failed and not the sealed electrical device.
Exception to that rule is any item where "Yeah, they all go at 55,000 miles" sort of items.
PCM
2.1 is not one of those.

Two hours later and I still dine on free coffee and TV.
I sincerely hope they are actually doing something back there........ my afternoon meetings have been 'blown' so far, so I hope to have a positive result at the end of this!
I hope it worked out for you. I just saw this thread. The screen went on my '06 CS
PCM
in a similar fashion except it gasped a few times over the last few times. I was lucky that it was dead when I got to the dealership since so many things work only for the mechanic. He knew right away that it had to be replaced and they ordered one for me and replaced it a few weeks later.
Hopefully your experience was as good. :cheers:
