Nextar-mp007 portable dvd

Hi,

Appreciate the "Ask Me". I am assuming that you tried the flashlight test.

Fixing the old one would of course require familiarity with electronic circuitry and components, use of a DVM & a soldering iron as well as availability of discrete components (your friendly neighborhood electronics part store may have them in stock). Normal culprits would be dried up, blistered or leaky capacitors. Rarely do the semiconductors break down (switching transistors) in an inverter circuit (but they would also from time to time). Often, it would be a case of cold/open solder and repairs involve is simply re-application of heat with a soldering iron and a dab of soldering lead. In instances where mostly everything checks out OK, it would be a resistor that has opened or gone up in value.

A replacement would be available (easiest to do). Most inverters used by portable DVD players are also used in laptops, GPS, depth/fish finders and other electronic devices that uses LCD display. That being said, the inverter would be manufactured by another company and would have their own part number not necessarily that of the player's manufacturer. Doing a Google for "inverter P/N" where P/N is the part number and you might be lucky.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
