ça te fait sur tous les jeux? dvd originaux et back up?Ps1 et Ps2?
tu changé de média ,récemment?tu graves en combien?
si sur originaux aussi , vérifie tes coils de ta lentille ensutie donne nous les valeurs en ohm
pour verifier ton bobinage
Taking the Measurements
There are 3 locations that can be used to measure the resistance of the coils. Although this is usually only required or performed when the laser or BA / LA chip is already damaged - I have included it anyway so that people can fault find their dead stations.
One of the locations is on the edge of two surface mount capacitors on the PS2 main board near the BA / LA controller chip. I wont discuss that location as it is measuring the coil resistance in circuit, which can provide false readings if say the controller chip is itself damaged.
What you are looking for:
1) Approximately 4.5 ohms across coil 1 & 2 = Good laser coils - check pots or clean.
2) Less than 1 ohm across coil 1 & 2 = Very Bad laser coils
3) Approximately 4.5 ohms across coil 1 & less than 1 ohm on coil 2 = Bad laser
4) Approximately 4.5 ohms across coil 2 & less than 1 ohm on coil 1 = Bad laser
Location (1) - requires the complete removal of the lens from the PS2. Also requires the removal of the plastic shroud covering the lens

Location (2) - Preferred location! - Requires only access to the rear of the lens. 400B laser shown,
