CD 304 , Tray and some tracking problems , has had some repair attempts before.<\/p>\n

\"\"<\/p>\n

Is this a orginal modification..?!<\/p>\n

\"\"<\/p>\n

Somebody added some extra tin to the Griplets<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Replaced Capacitors<\/p>\n

\"\"<\/p>\n

JD capacitors.., neverheard off<\/p>\n

\"\"<\/p>\n

Also -6 volt regulator has been replaced<\/p>\n

\"\"<\/p>\n

Repaired griplets , replaced belt, re-adjusted focus-offset , Focus Gain , Laser , Disc Height , checked eye pattern ect .<\/p>\n

\"\"<\/p>\n

 <\/p>\n

After Hours off playing, the problems starts again, when i apply some presure to the PCB the players loses track..i can’t find a broken trace, maybe a small crack in a SMD component is causing the issue. when i use a spare servo board the player is working fine again.<\/p>\n

 <\/p>\n

\"\"<\/p>\n

I can’t find the broken SMD or trace , so i took an old servo board and did \u00a0some refurbishment<\/p>\n

\"\"<\/p>\n

My very badly crashed test cd ..deep and wide \u00a0scratch<\/p>\n

\"\"<\/p>\n

Tracking and Playing Fine…<\/p>\n

\"\"<\/p>\n

Playing a \u00a0CD with lots of small scratches<\/p>\n

\"\"<\/p>\n

a closer look at the old board, when i touch the SMD with solder iron it fell apart<\/p>\n
