hey, I have a Sony D-EJ715 Discman. The problem with it is that the buttons on top of the case dont work anymore. Pic here. The remote that came with the player works at times, but i would have to replug the power supply to get it working again. The volume buttons on the side of the player also on works at times, but when i press either the (+ or -) buttons, it would automatically reduce the volume all the way down. Any ideas? I would get it repaired, but I'd rather use some of the money to get a MP3-CD Player.
Hi everyone!
I've been over the repair threads here and there and wonder if anyone with the Sony D-303 has service manual or have saved the actual resistance measurements (or plans on getting them any time soon) for the focus/tracking pots 501-505 on all points of measurement. This is one of the players with zero end points on the pots - 360 stuff. If I can get the resistance values, I can "ballpark" the settings and get really close without a scope, kinda like comparison checking an amp (R channel OK - L channel Dead) would be. I'm in the Philippines and the local Sony Service Center has no service info on this model and won't even consider looking at it. I'd like to thank ya' now!
Have you ever had the player open? - my very basic understanding of your problem would (to me) indicate that one of the connecting ribbons has come out of place...

I think the service manual would be your best bet... from understanding vwaps plight with his D777 when he messed with his pots, they are set up according to the transport... each one differs ~ so any results gathered from us here, with multimeters probably wouldn't really do you much good

Thanks for your insightful reply, but the values would give me a 'ballpark' to start with, albeit not optimum conditions. Another model could be used for comparison, but with results even more likely off the mark. There's a Sony Sony Service Center down the road but no manual or service available.
Does anyone with a D-303 know/can obtain the EFM test point(s) so I can 'Scope it out?
Further comments invited as always .. thanks again!
There's a problem with the ribbon thing-a-majigger, except it wasnt out of place, it broke. Maybe I opened and closed it too much so it broke; like bending a metal clothes hanger back and forth until it eventually brakes. O well. Thanks anyway
Okay, here's the problem. I just received a Sony D-5. I plugged a Radio Shack 9V adapter into the DC jack, and the unit started to smoke. I pulled it, and a few hours later tried the D-5 with it's docking station. It turned on, but nothing else happens (ie the disk doesn't spin, the LCD doesn't change it's display, no response to any button presses). Also, the unit doesn't turn off when I turn the power switch off (yes, there is an on/off switch on the D-5). I opened it up and found that not only does the motherboard surrounding the DC jack look slightly charred, but the ribbon cable leading from the laser unit to the motherboard is severed.
So my questions are these:
1. If the unit powers on, does that mean the dc jack is still functioning properly?
2. I know I need to replace the ribbon cable, but could that also be the reason why the unit will power on, but won't power off until I pull the dc adapter out, or is that problem the result of a fried motherboard?
3. Lastly, if I need a new motherboard, plus ribbon cable, does anyone know where I might be able to find these?
Any help is greatly appreciated. I only got to enjoy the D-5 for a few songs, but what I heard was by far the best I've ever heard. Please help me get this legend back on it's feet...
If the unit worked for a little while, then I really don't know if the severed ribbon connector is at fault...
I'd have thought you'd need a whole transport transplant... in that case... bye bye D5
Strange that you say the unit is ON, even when it is switched OFF...
