Some repair hints for TS-430

1. no display, no TX/RX with certain modes
   
   I read the article of Colin Robertson and I would like to tell you that my TS 430 S had exactly the same problem a few years ago soon after purchase. The solution was to replace the excessively leaking Diodes D3 - D7 but that meant to remove the front pane. It took the Kenwood dealer quite a long time to repair it. Meanwhile the exact replacement might not be available anymore. Therefore it might be a good idea indeed to add the diodes in series as you have described.
2. Low/intermittent RX After a few years of usage I faced the Low / intermittent RX problem. The problem were the Fujitsu print relays on the LPF board. I got around this by replacing all of them. Lucky enough I was able to find them with a major electronics parts distributor who has Fujitsu relays in store.
