Hello!
I'm so sad right now, because my beloved Panasonic DMR-EX84C is failing me, despite many hours of replacing each and every electrolytic capacitor inside, an effort now proven to be completely unnecessary. Why then, some might ask, did I bother going through with mentioned procedure in the first place? Well, in order to answer that I must first describe the symptoms my device is displaying:
Digital channels (DVB-C, haven't got a DVB-T antenna so I haven't tried that) have poor signal quality (but high signal strength) resulting in loss of sound and picture.
The same signal appears completely fine on TV connected to the device's antenna loop through jack.
The signal quality is poor no matter what cable I use.
If the device is unpowered for a few hours or more the signal quality is improved, only to become worse again after a day or two.
Analog channels are retrieved as normal.
All other functions are working fine.
There are some threads regarding similar units (in particular the DMR-EX75) that mention that these symptoms are caused by a failing capacitor (680 uF). No such capacitor exists in my unit, and no capacitor looked swollen or appeared to be leaking, so that's why I replace all the capacitors.
Sadly enough, this did not solve the issue, so now I'm turning to you in hope for some other possible solutions, before I admit defeat and upgrade to a blu-ray recorder.
