Hello. I just finished replacing all the electrolytic capacitors and all the lamps on my Beomaster 1900 and the repair went well regarding the issues to be fixed: before completely achieving the re-assembling, I tested the amplifier and everything was fine: no more hum, good sound and all the lamps operating as expected. However, when I went further in the remounting, the Beomaster could not be operated as explained below.

With the Beomaster partially remounted, i.e before mounting the front panel, everything works fine: selection of program (phono, tape, FM), volume adjustment, on/off switching work perfectly by directly touching the pins on PC-board with my finger. However, with the front panel in place (with the sensitive keyboard), nothing happens: the amplifier is in stand-by and it is impossible to switch it on, only the stand-by LED is on. I dismounted and remounted the front panel again and I carefully checked that all the bronze forks grip their respective pins (not easy and quite long): the problem remains the same, the amplifier perfectly responds to any programming action by directly touching any pin while there is no operation possible through the front panel. I probably missed something but I cannot see what. Any help or suggestion would be very helpful. Many thanks.
