BrianRP Posted March 30, 2013 Share Posted March 30, 2013 Has anyone experienced problems with this combination. HST with standard chip works fine, the sound chip works perfectly. After a few days of inactivity the HST when fitted with the sound chip will not work until the HST is run for 5 minutes with the standard chip. Customer service from both Hornby and SWD has been excellent but they are both stumped by this problem. Link to comment Share on other sites More sharing options...
brando Posted April 19, 2013 Share Posted April 19, 2013 Hi, this is not a fault , it is the nature of sound decoders.All sound equipped locos do this. Link to comment Share on other sites More sharing options...

2e0dtoeric Posted April 20, 2013 Share Posted April 20, 2013 None of mine do, either! (presently 10 in number). Link to comment Share on other sites More sharing options...
walkingthedog Posted April 20, 2013 Share Posted April 20, 2013 Are you saying you have to remove the sound chip, fit the standard one, then refit the sound one and Brando says this is normal? I don't think so. Am I correct to say that locos with sound chips have to go through a sequence before the loco will move? Link to comment Share on other sites More sharing options...
Fishmanoz Posted April 20, 2013 Share Posted April 20, 2013 I suspect Brando may have missed the change of the chip bit and is referring to your start up sequence requirement, which I think is correct. The idea that a sound chip, on fitting to a loco, can tell if the loco has just run 5 minutes with another chip or not, sounds far fetched. But then I can't explain why the chip would not work on a cold loco, then later work on a warm loco whether it has had another chip fitted or not. Brian, can I suggest you try this for the purposes of elimination. Take out the sound chip, fit a blanking plate and run DC for 5 minutes, then refit the sound chip and see if it works. And does the chip work after just removing for a short time then replacing without any 5 minute thing? Does making the remove/replace time 5 minutes make any difference (I'm struggling here but thinking capacitor leakage discharge time here as a possible effect that allows the chip to reset and start up again). In summary, subject to what you find from my suggestions, I'm thinking faulty sound chip here - return to supplier for replacement under warranty.

brando Posted April 24, 2013 Share Posted April 24, 2013 All the sound chipped locos at my club all take about 5mins to respond to control. We do not have to remove the decoders. Link to comment Share on other sites More sharing options...
Fishmanoz Posted April 24, 2013 Share Posted April 24, 2013 So Brando, is this 5 minutes during which nothing happens, or is it 5 minutes during which the loco runs through a startup sequence of sounds before it will respond to throttle? Link to comment Share on other sites More sharing options...
