I found the usual c1270, c1271, c1272 capacitors bad and replaced them. I also had some other bad capacitors on the power supply board and a few on the video board and replaced them too. Now my unit powers up, goes though the self test, operates for about 1 minute and shuts itself down. Anybody experience this? Thanks
the fan connection seems to be fine. The fan turns on about a minute after the self test. the fan runs for 3-4 seconds then the fan and the unit shut down. I have 6.95 volts for the 3-4 seconds the fan runs. I disconnected the fan and it does the same thing with 6.95 volts at the pin for the fan power for 3-4 seconds then the unit shuts down.
Probably worth sending a message to mickinct about it to see if he's familiar with that failure mode, and what its likely problem source might be -- if it needs repair and you want to salvage its use, he's your man to properly take care of whatever ails it (this from personal experience with my E85H).
If you found out how to fix this, please let us know!
We suddenly had the same problem starting a little while ago after nearly 8 years of great use of the DMR-E85h
I, too would like to know if mickinct had any thoughts on this or was able to resolve the problem(s). None of my many Panasonics go back to the 2004 model year (like the DMR-E85H) but one or two more recent models have had the same problem. After considering all the possibilities I deemed that there was a problem with the Digital PCB.
For the affected models I didn't have any known good COMPATIBLE Digital PCBs to swap into the machines. Where I did have a close known good Digital PCB replacement on hand I swapped in that Digital PCB with somewhat better, but still unsatisfactory results.
I reported this experimentation over several posts, beginning here:
