After my eye surgery two weeks ago, I was doing some simple checking of equipment this afternoon,
I can do this with one eye, but no detail work possible for a few weeks yet

I have just noticed that one of my Tx22s LEDs flashes really rapidly when switched on.

Is it broken?

May be.

I had a similar issue last week with my old transmitter.

Could only fix it by now by replacing the Tx2 board.
It was one of the very first Tx2 boards.
Had no time to look for the reason more seriously.

Nevertheless you should make sure first, that battery voltage is ok.

Thanks Juergen,

I checked the battery and it was OK.

I feel like an idiot, because the problem was the inertia pot was not completely off.
I checked the grub screw and it was loose.

All working OK now - doh!

Ah, interesting.

I use a profile without inertia.

So maybe there was a problem with the profile setting on my Tx,
as I have a toggle switch on Ch2 that is normally in the middle position.

I built my Tx's from kits

(yes it was that long ago)

and I built them without the Inertia control....

There are several possible reasons

- low battery voltage
- dirty or bad inertia pot
- broken wire / bad connection to inertia pot


Does the Tx still work or appear to be dead?

Thanks Andy,

the problem was the inertia pot was not turned completely to the left,
and the Tx LED flashed rapidly when it was switched on.

I have not checked the Tx for normal operation,
so will try it out with a couple of locos.
