[Kenwood] TS940S Display Error

[G3OOU@aol.com]

Hi All

For your information: I have just acquired a TS940 that had the apparently well known blank display problem - just a row of decimal points. Having followed up the "faulty ROM socket" line of thinking and found that to be OK further investigation showed that the 9MHz oscillator using transistor Q1 on the carrier board (X54-1840-00 A/2) was running at 6MHz and the device voltages were very unusual. Replacing the transistor with a close UK equivalent solved the problem and the transceiver is now running fine. Not an easy beast to work on though and requires careful juggling to run with some of the boards folded out.
