I have replaced a couple of blown electrolytics including the 2200uf one. Now the combo runs but with issues. For example, the power supply runs scorching hot. The hottest spot being the rectifier diode mbr on the heat sink, just behind the 2200uf electrolytic that bursted (not shown, already replaced). Also the unit continues to display "finalizing" on the screen after dvd burning, even if the finalized disc is ok. To get rid of the "finalize" i have to turn the unit off and let it cool for five minutes. It is challenging for me because i don't have a schematic. Here are some pics.

I think heat is usually caused by underpowered caps. Even if rated high, they can still be too weak.
Sometimes the PCB is just rated too low, so bump it up.
