hi peeps. i have searched through the other threads and haven't found a problem quite like mine. i've got a 919 here that i suspect was dropped, or subject to some other physical shock. (big dent in the side of the case)
when i turn the unit on, the bottom pickup slides towards the back of the unit and then begins grinding loudly. the laser lens itself is vibrating while it does this. i only let it happen for a few seconds before i pull the plug.
if i reset the pickup by hand by coaxing it to the front of the machine and turn it on again, it does the same thing: slides to the back, very loud grinding.
FYI, before this, the unit was mostly dead. i replaced C116 on the power supply plus the main filter cap for good measure so at least it's showing more signs of life. but i am still not getting a blue power LED and nothing appears on the display.
any idea what's going on with the pickup? i am strongly suspecting that something has been shaken loose or out of alignment, but not necessarily broken off, as i haven't found any loose bits inside the machine. thanks.

yes that's gone. rein-o wrote: Not sure what you mean by power LED, it should be on or lit as standby I think, or that's how my 503 is, its always red then the front display lights up. from what i understand, when the machine is on, the standby LED is supposed to be blue, right? on my machine, it turns red when the power is off, and does not light up when the machine is on.

P213 also blown. shocker. exact same fuse. weird looking Littelfuse knockoff green 125V/1A. the other pico-fuses on this board are yellow and made by someone else, and they still all test good. both trays now work. bottom pickup and assembly moving up and down and around, until it got jammed. getting closer.

Light is supposed to be red and off like you said, never saw blue, must be something else I can't remember. Sounds like you are doing more than I know of Good luck with it and enjoy the player once its back up and running. Also that second laser is for the DVD playback, if you can't get it to work I wouldn't worry, these older DVDs aren't really worth bothering with, keep the LD parts going
