Μετά απο αιώνες ένας παλιός εφιάλτης (για μερικούς) ξανάρχεται.
Ο φίλος Peter απ την Σουηδία προτείνει τις παρακάτω αλλαγές
How to minimize mains leakage in switch mode power supplies
Generally, locate and remove any capacitor in parallel with the isolating HF transformer.
This is typically a ceramic high voltage capacitor, 470pF – 3.3nF, often blue.
This applies to CD/DVD players, TV set top boxes etc.
For Bluesky DVD players using the San Ji Electronics GL001-A1 power supply board:
• Locate YC1 just beside the HF transformer, 2.2nF blue.
• Remove YC1.
• Also make sure no YC2 or YC3 capacitors are mounted (normally not in European version).
• Use ferrite beads (or two turns on a bigger bead) on the power cord, or a good non-resonant power line filter.
Good luck!
