Thanks for all the replies. I will try these suggestions tomorrow (working today) and post my results to the list for future reference. I will try the heat test on the LPA finals and driver first as I have all the panels off and it will be a quick way to find out if that is where the problem lies (kind of leaning that way).
Fred, I read some of the same comments with regard to the firmware reload. I did in fact reload it a couple of times but not with the same power on/off/removal procedure you stated. If the LPA test is ok, I will try the reload again using your sequence. I always turn the K3/P3 off and then back on again after a load, but I have not tried the power removal technique. Thanks again guys and I hope to have some results early tomorrow morning. 73, Dave W8FGU On 6/18/2012 6:37 PM, Dave Van Wallaghen wrote: > Hi all, > > Before I contact service, I thought I might post my problem here in case > it is something fairly simple. > > I returned from a 2.5 week vacation a couple of weeks ago and sat down > to do the firmware upgrade to my K3.
