What capacitor do i need to replace the old ones in DMR-E85R to fix the problem with "please wait"
Best bet is to replace all of the electrolytic capacitors in the power supply one by one, noting original capacitance values, and voltages (capacitance values are marked in µF as well as their voltage on their jackets), uprating the value/voltage where necessary, and observing polarity (the negative pole is marked by a stripe down one side of the cap, and replacements should have this opposite the + symbol on the board) when fitting new ones in the PSU.
It may also require replacement of IC1, a 12V 5 pin IC regulator, since this may have been partially damaged by the increased output voltage of the failing electrolytic caps in close proximity to it. This device has its type number (prefixed by STR) on its face, and should be available from Panasonic. Make sure if you order a replacement, that it is for THIS MODEL only, and that it is for the power supply in this unit.
Before you go out and buy a whole bunch of new electrolytic capacitors (available from most electronics stores including Radio Shack etc), take a visual look at the power supply (unplug unit from power point, and carefully remove the power board.) Examine it carefully, and note each capacitor that you can the value/voltage of - write it down, and obtain the closest replacements of each. Don't panic if you can't get a 20V 680µF, use a 25V 1000µF instead.
The total cost depends on how many electrolytic capacitors require replacing, but it is best to replace ALL of them one by one, to ensure reliability of the circuit they are in, in this case, the power supply. Don't worry about the IC regulator or any other parts just yet, do the caps first, as these are not terribly expensive, before taking any further action.
