NEXTBASE
MODEL:NB-785
DVDPLAYER
No power problem and solution.

Initial Troubleshooting:

1. Totally deadset unit.

2. There is an output voltage at the filter caps 350V.

3. No DC output voltage like 9V and 5V this means that there is a problem in the smps circuitry.

4. I visually inspect the board and I found out that there is a burned resistor near the filter capacitor.

5. Using ohmmeter I test the 220k ohms resistor but it was infinity open circuit.

6. I replace it and test the unit and it works like a charm. DVD is working and it is playing now my favorite audio CD.
