marconi 2386 RF unit
« on: July 09, 2017, 05:18:10 am »
Hi
Recently I got an Marconi that it is separate in two part
1-   Display 2380
2-   RF Unit 2386
First it had overload error that I could solve by service manual Page 33 chapter 5-3 (short TP12 to TP1 on AC2/1)
But after I connect rf unit again   it shows overload error
I surf on internet all sites that mention on it https://www.eevblog.com/forum/repair/repair-documents-and-links-sticky-me-please-mods/
But I couldn’t find rf unit service manual if anyone had have experienced about this problem I am so glad to hear from you.
