Hi All, I’m having the scan twice no selection issue again with this DS100. Using the troubleshooting chart and the test terminals, it leads me to test K where the test lamp doesn’t lite and tells me it’s a write-in issue. Taking some voltage measurements, a few odd things are, the selenium rectifier in the tormat receiver is supposed to measure -25 vdc, I’m getting -40 vdc. On the test points, points G-H should measure -300vdc. I only get that when a record is playing. When idle, it’s only a few millivolts. I have Mike Zuccaro’s DVD Repairing the tormat selection receiver and when I see him testing that point I don’t hear a record playing so I’m guessing that these voltage test are when the mech is idle. The battery trick works and every selection plays. Does that eliminate the detent switch and anything else? All contacts on the tormat selector and in the pricing unit cleaned and checked including the relay which I know is important. When the mech is scanning, the OA2 tubes flicker like they should. I have checked all the caps and resistors in the receiver. All caps are good including the .05 in the pulse amp. I would really appreciate any help or suggestions. I’ve been trying to figure this out on my own for the last few months and don’t have much hair left to pull out. Thanks, Doug
Hi Doug, Since the battery trick works, that proves that it is a write-in fault that you are dealing with (detent switch etc OK). The "K" test that you have performed with the test lamp narrows the fault down further within the write-in circuit - the obvious first thing to check is the trigger switch in the credit unit (is it clean and the contacts in good shape?). There is a simplified write-in schematic on page 1437 of the service manual.

Doug. I recall having this same issue once with same model. Ron Rich coached me through some troubleshooting and it ended up being a one watt resistor in the receiver that was out of tolerance Unfortunately I can’t find my notes about which specific one it was.

Well.... I thought I may as well check all the caps and resistors again. It turned out to be the .068 cap. I had replaced that one when I checked them the first time and I always check the value before I install them. Not sure why but the value went from .068 to .03. It's working good now. Thank you so much. I am happy to get this done!!

I thought I may as well check all the caps and resistors again. It turned out to be the .068 cap. I had replaced that one when I checked them the first time and I always check the value before I install them. Not sure why but the value went from .068 to .03. It's working good now. Thank you so much. I am happy to get this done!!

I recall having this same issue once with same model. Ron Rich coached me through some troubleshooting and it ended up being a one watt resistor in the receiver that was out of tolerance Unfortunately I can’t find my notes about which specific one it was.

I pulled the pricing unit out. cleaned every contact. I used an ohm meter to make sure they were making good contact. The problem is still there.

Hi Doug, Since the battery trick works, that proves that it is a write-in fault that you are dealing with (detent switch etc OK). The "K" test that you have performed with the test lamp narrows the fault down further within the write-in circuit - the obvious first thing to check is the trigger switch in the credit unit (is it clean and the contacts in good shape?). There is a simplified write-in schematic on page 1437 of the service manual.

Using the troubleshooting chart and the test terminals, it leads me to test K where the test lamp doesn’t lite and tells me it’s a write-in issue. Taking some voltage measurements, a few odd things are, the selenium rectifier in the tormat receiver is supposed to measure -25 vdc, I’m getting -40 vdc. On the test points, points G-H should measure -300vdc. I only get that when a record is playing. When idle, it’s only a few millivolts. I have Mike Zuccaro’s DVD Repairing the tormat selection receiver and when I see him testing that point I don’t hear a record playing so I’m guessing that these voltage test are when the mech is idle. The battery trick works and every selection plays. Does that eliminate the detent switch and anything else? All contacts on the tormat selector and in the pricing unit cleaned and checked including the relay which I know is important. When the mech is scanning, the OA2 tubes flicker like they should. I have checked all the caps and resistors in the receiver. All caps are good including the .05 in the pulse amp. I would really appreciate any help or suggestions. I’ve been trying to figure this out on my own for the last few months and don’t have much hair left to pull out. Thanks, Doug _______________________________________________ Jukebox-list mailing list -- jukebox-list@lists.netlojix.com To unsubscribe send an email to jukebox-list-leave@lists.netlojix.com %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Searchable Archives: http://jukebox.markmail.org/ _______________________________________________ Jukebox-list mailing list -- jukebox-list@lists.netlojix.com To unsubscribe send an email to jukebox-list-leave@lists.netlojix.com %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Searchable Archives: http://jukebox.markmail.org/
