how can i fix my panasonic dmr-e55eb/ebl dvd recorder?

The reason your player will not record correctly and keeps self checking is because there is a faulty regulator on the power board. It is easy to fix and parts are available online, but you need to be able to use a soldering iron and take the board out to fix it. This is a common problem especially if the unit is two or three years old, but as I say it's easily fixed.
