I really didn't want to start a new thread on it, but I hate to rob someone of their precious star (R-O-F-L).. so here goes.

The problem which appears to be almost common enough to induce a recall (Toyota?) is the following:

You are playing for some amount of time and the amp starts reseting.  Sound cuts out.  Lights turn off.  Takes a couple of seconds.  Comes back on just long enough to repeat the process all over again.  In my experience, if I turn the amp off, cool it down, turn it on... I can play for a while before it does the reset thing.  Also, if I set the head up so that an air conditioner vent is blowing cold air on the backside, I can apparently play for as long as I want.

Smells like overheat, right?

Please respond if you have first hand knowledge of not only the problem, but the solution.  And I'm really, really wanting to give the holy star if you can tell me the following:

A) What is the true cause?

B) What is the component(s) to be replaced?

C) Is the replacement component redesigned to fix this issue?  In other words, do we just stick the same part in and keep repairing these heads every few months (G0D I hope not)?

Please respond if you are a consumer of SV MK1, and has taken the problem cradle to grave, or you are a Line 6 tech or engineer who can expound intelligently on the repair.  You need not respond about your "best guess" or electrical fundamental relationships or any other nonsense.  Please stay focused on A-B-C above and only respond if you are (once again) owner with the issue or Line 6 dood. I'm not trying to be a d*ck... I just want a real answer. I only need one.  I don't need a life story.  One paragraph will probably do.  If it's any longer than that, we have failed and have most likely entered the realm of "best guess" and "life story".  You will not get star (one again ROFL!!! the star... I love it!).

For what it's worth, my head is already at authorized repair center (Inner Sound - Portland, OR), and to them it's almost a forgone conclusion that it's DSP.  But once again... Why? And Is the next DSP redesigned to avoid overheat conditions under normal use?

Thanks and sorry for the duplicate post.  I hate doing that.
