Can't we just delete such time-waster topics if people aren't qualified enough to start threads with some kind of minimum informations we need in order to give support, like:

- model?
- what issue/symptome?
- is it permanent/sporadically?
- already performed measures?
- PM status of the machine (in case it might be relevant)

Maybe, after some public brainstorming, a mod can write a little guide and make it sticky somewhere so at least we don't need to teach pre-school basics and re-invent the wheel all the time. Maybe it's just me thinking that these insufficiant threads are a growing phenomenon.

Most people ask for help at Yahoo or Fixya first...where you can remain annonymous,ask your question and still leave just as clueless as when you went in.
I think people forget that the vast majority of replies here are coming from actual techs in the field....unlike Yahoo or Fixya etc.

You might want to consider checking the start date of this thread dude, and then perhaps browse the history and input of the contributor that you're so pissed off at for NO reason, and then tell us what makes you so damn awesome with your 4 big posts in as many years.

apologies as this was not directed at those who leave great info . but rather to the one who had earlier posted about the time waster type of threads. Keep on helping each other that's a god thing.

DOES anyone know how to fix this code?Pcu's and dv's are not old.Thanks

Before you replace anything execute reset.
Press yellow key, 107, red key for 5 sec pressed . and at the control panel select copy sp . Turn off and on machine .
If error code remains we had to know the model.
