    TS-830 frequency display is missing segments of the numbers. Looking for answers to repair.
    Thank you,

    First thing I would try would be to loosen then re-seat (good and snug but not over torqued) all the mounting screws on all of the PCB's, special attention to the AF board and of course the display board.

    Olaf Rettkowski DL9AI, has a TS-830 survival guide out there on the Web. Might just have the information you are looking for.

    I opened the rig up and tightened all screws and when I loosened, jiggled and re-tightened the display board the problem went away. I leave both TS-830's turned on 24/7 usually with just the Heater Switch on.
    Thanks for the advice!

    Intermittent board grounds were a problem with the early '830s. Mine required star washers added to the AVR board mounting hardware (per a Kenwood service bulletin) to get it to behave. This was shortly after the radio hit the market.

    With rigs this old, checking board grounding and cabling as part of preventative maintenance is usually a good idea.

    I think that same service bulletin mentions adding a wire under said star washer and solder the other end to the GND test point.

    I had added stainless star washers under various screws, but missed a couple. Got it all fixed now thanks to the group.
    I have that TS-830s set up on 10 meters using a 4-element wire collinear. Not hearing much, but wire is presently oriented North/South and not up high enough yet. Waiting for leaves in the trees to clear off so my sling shot will work.
