Ouverture Tuner Board Type
in General Discussion & Questions · Apr 14, 2018 00:31I recently purchased an Ouverture. Everthing appears to work except the radio. The person I bought it from said that the radio suddenly stopped working. It will only tune from 76.0 to 89.0 Mhz. Hmmm that looks like freq …

Beocord 7000 Capstan Motor issue
in Imported Content (Unmapped) · Jan 3, 2015 05:08I have a Beocord 7000 where the capstan motor often fails to spin when pressing play. If you give the spindle a gentle flick, it will start to spin. The unit plays ok. Even with no drive belt in place the same fault occu…
BM7000 issue after Lithium battery replacement
in Imported Content (Unmapped) · Jan 17, 2014 08:49I can confirm that point is indeed TP1 . BM indicates 88 when test mode is initiated. I've gone through the different test functions. Test 5 (RAM/ROM test) produces code 37. That is not in the list of codes in the servic…
BM7000 issue after Lithium battery replacement
in Imported Content (Unmapped) · Jan 17, 2014 04:48Here is a photo looking at the back of the CPU module. Lithium battery is located directly on the other side. Is TP1 in the upper left corner surrounded by the ground plane ( just above where the metal shield would cover…
BM7000 issue after Lithium battery replacement
in Imported Content (Unmapped) · Jan 16, 2014 08:13Thanks. That worked. However, I'm still wanting to get the BM into Testmode. I cannot identify from the drawing which pin to short as it only shows the area and not which pin to short. Here is the article that I'm lookin…
BM7000 issue after Lithium battery replacement
in Imported Content (Unmapped) · Jan 16, 2014 05:28With a scope on CPU pin 12, IR input, I can see data when pressing a key on the remote. So I'm hoping that your suggestion of setting the option is on the right track. However, I'm having trouble identifying TP1. The cir…

Beolink 7000 back light and recapping.
in Imported Content (Unmapped) · Dec 23, 2012 21:18Great advice. Also, I store any boards I'm not working on in anti-static bags. A computer shop is often a great source for these.

in Imported Content (Unmapped) · Dec 23, 2012 02:59The battery is a Sanyo Lithium CR2430 (24.5mm diameter by 3mm thick). I bought some replacement batteries locally that have the solder tabs. I definitely wouldn't recommend soldering directly onto this type of battery. T…

in Imported Content (Unmapped) · Dec 22, 2012 07:34Disassembled my next BL7000. Here is the reason why I remove the CPU board and replace the battery. I've desoldered one leg and bent the battery back on the other leg exposing the underside of the battery. As can be seen…

in Imported Content (Unmapped) · Dec 21, 2012 07:55Hi, I also have a couple of BL7000's that have fairly weak back lights. After reading this thread I decided to have a go at replacing the backlight as well as full recap and battery replacement on both BL7000's. I ordere…
What Are You Working On Now
in Imported Content (Unmapped) · Nov 15, 2012 00:36I agree. Differing opinions can be a good thing. You both provide a wealth of information to this forum and it would be a sad day if the forum lost you over something like this.
