Fixing the "Self Checking" problem of Panasonic DMR-E55 DVD Video Recorder

I have Panasonic DMR-E55 DVD Video Recorder and suddenly it start to get reboot when the system performs “Self Checking”. Because of this reboot problem I may not be able to record DVDs and need to put some extra effort to eject the disks. Most of the times this reboot occurs in cyclic pattern and to break this cycle I need to be eject the DVD disk manually from the system.

While examine the system my primary attention moves on to the “Digital RAM card” of the system (Because it actively involves in to the DVD burning process). But after the 2 weeks of continues inspection I found that the problem is in the SMPS primary chip - STR G6535.

After replacing the STR G6535, system starts to work in an order.

Replacement of this chip is not a complex process but while doing that it is necessary to put some attention about the SMD components located nearby.
