FT-901DM loss of digital display and audio

Postby KE0BK » Mon Sep 26, 2016 1:39 pm

My recently acquired FT-901DM (vintage 1978) sent a curl of smoke from the left side while I was monitoring the 40 meter band. I immediately powered it down. and removed the top cover. After powering up again, the digital display and all leds were dark and there was no audio. I removed some boards for examination and noticed that the large electrolitic caps on PB-1717 & PB-1708 had an amber colored substance encircling their base. Is this a sign of leakage or was an adhesive used to hold the upright? I've ordered a cap replacement kit. Any advice would be appreciated.
