[Kenwood] TS-930SAT: Intermitent on air / autotuner LED

[YU1WC Vladimir Ljubojevic 'Fric']

Hello,

The "On Air" and "Auto tune" LED indicators (red/green) on my TS930S/AT 
(ser.no. 4xxxx)  are working intermitently. Recently, they stopped to light 
on during transmit / auto tune. All other functions of the radio seem to be 
OK. However, from time to time those LEDs resume working properly for a 
short time, then turn off again. So the LEDs themselves are not dead at 
least. The third LED indicator at this position (Notch) is working OK.

I can live with this, but I am worried if this can be a signal of a greater 
problem. The On Air / Auto Tune LEDs are activated from Signal unit board / 
Auto tuner board respectively, but I supose that in the root they share a 
common signal for activation somewhere in the PA section, TX relay or simmilar.

Anyone has an idea where should I check for a stuck relay contact, bad 
connector or some other faulty component?
