Quite many possibilities. Since you replaced the IC, I'd figure you have a little understanding of electronics and ESD procedures. You now need to troubleshoot the driver for the display. Do a little research with your DVM... make sure the display is getting V. Should the unit be a uP type system, you are probably looking at the uP display driver circuitry [all in one] being bad and no way around the replacement should you desire a display. Should the unit be slightly older, you may get lucky with finding a cap or transistor problem for the driver. Moreso trans than cap.

Wish it were here.. always easier to take a peak and find the problem when it is in front of me.

Why won't dmr e85h pick up all the digital channels the tv attached to it will? Is it outdated technology? Do you need a digital set top box or completely replace the unit? Anyone...?


You most likely will need a set top box connected to this recorder in order to receive digital channels, Assuming the DVD recorder works besides this detail, you should not need to replace the unit. Only replace it if it DOESN'T work.

The DMR-E85H is a 2005 model so it is more than 5 years old.

Pan. dmr-e85h turned itself on, self-check


Open case and look for failed capacitors, which are cylindrical and will have a bulging top and a yellow/gold substance leaking out. If this is the problem, search for previous solutions that mention "solder capacitor C1260" for the DMR-E85. I had a similar 'no power' problem with my DMR-E55 and my son and I were able to fix it Sunday. Not hard to do and mine is working again!

Panasonic dvd video recorder dmr-e85h is dead


I had same problem. I replaced two bad capacitors on the power supply card. See http://vassfamily.net/projects/DMRE85H/dmre85h.html The capacitors I replaced were C1260 and C1261 slightly different from the one on "vassfamily.net". Everything works now for me...

Good luck.

Also for those interested, I found the "commands" listed on http://www.dxcc.com/dmr-e85h.htm useful when operating the DMR-e85h to correct problems.
