Hi Vincei, I don't know if you remember me, but we corresponded on the subject of ES gear a while back. I'm writing to you to inquire if you discovered any solutions for 7 series ES players with dying lasers. I have an X7 with this issue. I know the lasers are no longer made, but I keep hoping that one day someone will make replacements, so I can fix this player. Regards, wu6fiend
For the resistor, the voltage going to the lamps was 8v, so I used something like a 680ohm to drop it enough.
