MD1488 Posted October 22, 2018 Report Share Posted October 22, 2018 Hello, I have a MDS-JA333ES that I had not used in several months, when I turned it on, none of the buttons lit up and the screen was dead, but it did accept and play a disc then after about 10 seconds the screen lit up and flicked then the machine shut down and now will not come back on and is completely dead. The power relay click once when I power it off after its been on but does NOT click when I first re power it. I opened it up and found nothing obvious, damaged or burnt etc, are there any fuses or things I could check? anyone had these symptoms before? I am in Perth Australia and there are no service centres for MD in my area, any help appreciated. Quote Link to comment Share on other sites More sharing options...
kris01 Posted October 23, 2018 Report Share Posted October 23, 2018 I would check all connectors, flat wires if not broken. Quote Link to comment Share on other sites More sharing options...
sfbp Posted October 24, 2018 Report Share Posted October 24, 2018 I can't remember if there is a FUSE on the power supply..... seems possible. But Kris is right, a damaged ribbon cable seems likely. Quote Link to comment Share on other sites More sharing options...
kris01 Posted October 24, 2018 Report Share Posted October 24, 2018 Check connectors which are accessible from the bottom, under loading tray. Once I forgot to put it back and symptoms were quite similar to your case. Quote Link to comment Share on other sites More sharing options...
PhilippeC Posted October 25, 2018 Report Share Posted October 25, 2018 External old cables can give those symptoms, specially when a very little mouse is implied. A rabbit also if you have one... High level of humidity in the air tend also with time to destroy slowly the plastic of the cables. Quote Link to comment Share on other sites More sharing options...
cosmolv Posted October 27, 2018 Report Share Posted October 27, 2018 From sympthom i see that problem is on display power section at regulator/reset gen IC. But it need inspection to say for sure. Maybe some solder joint cracks - thats normal for old units. Maybe solder joints on power transformer. Maybe some capacitor went bad. But first is visual inspection, then measurement inspection etc... Quote Link to comment Share on other sites More sharing options...
