My E85H went totally out the other day. Had been experiencing the dreaded 'please wait' syndrome for the past month but started working again. I e-mailed Panasonic and they told me to send it to;
McAllen Service Center
4900 George McVay Dr.
Suite B Door #12
McAllen, Tx 78503
Said it would take 2 - 3 weeks, include a note explaining the issue. They do not need the power cord or remote. Also said charges would $50+parts+shipping. I assume labor will be higher after they determine what the problem is.
Have you looked at this thread http://www.fixya.com/support/t216825-dvd_recorder_frozen_please_wait_display
. I followed the well written advice/instructions, took mine apart tonight and found 3 bad capacitors which I will be replacing tomorrow. If I have the luck that the others have reported my unit should be up and running tomorrow night for under $10 and a little time. Hope this helps.
