The OP photo is not of sufficient clarity to see if there was a solder bridge or stray wire strand across those 2 pads, but likely something was conductive at the gap.

There are 2 x CL66 loads for the HM7K, the normal one and the KC3 one that plays the National Anthem.

Is it showing as connected in the app - blue icon.

Surely they would just send you a straight replacement. No need for refunds and repurchase.

V3.6R ?

Hornby are asking what revision state your LZV100s are running. Their units are very old but they intend to have one updated (to v3.6?). They think this affects availability of functions over F12. Can anyone confirm this please versus revision states.

if you want to blow the decoder you can try - against all published advice.

Nothing you did wrong - there is a glitch loading multiple TTS profiles. Use this convoluted method until it is fixed. If it is a regular HM7K profile you are talking about then load from the profiles page rather than the loco page.

I use 4 digit addressing from an Elite without problems. A couple of glitches that have been seen with long addressing. If you load a new or reload an existing profile you have to over-type your long address again in loco settings even if the address is showing correctly, then refresh CVs in the app editor and check CVs 17 and 18 have written the correct numbers for your chosen address. Some have been translating wrongly, in either case the decoder will not respond. The other glitch currently under fettle is CV 19 (consist) address can shift from default zero to any number (often 16), meaning although sound works independently the loco thinks it is in a consist and will not work on the decoder home address. If you can confirm those possibilities are not in play then I can escalate the LZV100 case up the ladder for investigation.

F24 toggles the steamer on/off, but I am not sure which is default on or off, - I would think the function mapping is such that F1 also turns F24 on meaning the next F24 action is turn it off. I will check. Ref the sound file - out of the factory it is loaded with the correct profile and default out of the box operation should be DCC. However updates are issued and it is wise to use the free app to upload the latest version if there is one. Your ECoS track power is fine to allow the app to work.

Is 10 seconds running time with motor. Lights and sound not enough, or is there a different reason you would need 2. Edit - charging time. The decoders have been updated to charge while static after a couple of seconds delay. This is to prevent a surge on start up and to cater for the DCC programming track case. A programming burst is over before the power bank gets its timer running.

I hope you didn't think you could now load TTS sounds. The facility for TTS profiles is purely for the function key mapping, not the sound. The sound is burnt into the decoder at the factory and cannot be reloaded onto a TTS or any other decoder. The import you are trying to do is simply to save you typing in the functions key allocations again. When you go to that profile that is the only option for that very reason. Edit - just to reiterate the process for a dongle operated loco. 1. Set up that loco in the engine shed. This includes importing a function key map for TTS locos. 2. Go to manage dongle and assign that loco to the dongle. 3. Rinse and repeat for other locos. 4. Each such loco will appear on the control screen ribbon with the dongle shown as its 'decoder'.

My 108 2-car pair ran great on DC but since adding a decoder (old Uhlenbrok pair) running has been unreliable, stopping on bends for a moment being typical. At some point when I am brave enough the top will come off again and a HM7K decoder will be fitted with stay alive to the motor coach. The dummy can stick with the old decoder as its only for lights at present, unless I want twin motor sounds.

Be aware F24 turns the steam unit on/off independant of F1. Obviously F1 is required for the noise but F24 is the atomiser power. CVs 211 and 212 alter the steam volume at chuff and idle.

Some decoder boards do have C+/- solder pads but the manual says these are for development purposes. I would think they are suitable for hard wiring, but why do so when a plug-socket is provided. DIY or other make stay alives are unlikely to work as they will not have the additional components found in a Hornby power bank.

This has been covered before on this and other forums. The dongle will work if your controller has an RJ port that supports Xpressnet. Some controllers have a port but it is for Loconet which does not work with the dongle. There are other controllers that support Xpressnet but have a Din socket and these may work via a suitable Din-RJ adaptor.

Wrong - anywhere a loco can leave and come back to the same place is classed as a reversing loop. This may be a tear drop or Wye configurtion. The trick is finding a simple common track to control polarity/phasing in.

The dongle is a simple relay device. It passes along what the app coomands but if the controller is restricted in ability to send those instructions they are ignored. You cannot expect the dongle to magically enable a basic controller to work outwith its spec.

As previously reported there is a glitch in the app whereby DCC control is lost. This can either be lack of response, usually because a consist address has bern invoked by the bug (reset CV19 to zero to fix it) or there is runaway due to CV2 (kickstart) being corrupted to a high value - (reset it to 0 or 1 to fix)§. It is thought the decoders may see variable track voltage (grubby rails, etc) as programming commands and corrupt certain CVs.

Since Gaugemaster took over the Train-Tech product range links to my review and the smart screen writer have been lost, but this gets you to the writer files, the .exe file being the app and the others info documentation, etc. https://1drv.ms/u/s!AhG7bX4H0NOt_VTPajMM54kI0dUt?e=SfCkf2 and this gets you to my review (video clips can be slow to load on some browsers). http://www.halton96th.org.uk/smart-screen1.html Edit - note the latest writer is slightly different to the earlier version shown in my review but functionally the same end result.

The Power bank (stay alive) will cope with the dead spots, but several folk report using the decoders with dead rail. Just ensure you build in adequate short circuit and charging protection as LiPo batteries burn easily if abused.

Final testing, so should be available soon. Keep an eye on the app as it will just pop up.

Reminds me of those on line pleas from folk doing a degree/masters/phd asking for other folk to supply them with enough material so they can throw a thesis together to pass their exams.

That has been identified as a memory problem in the app that was slowing scrolling of the profiles, so the logos have been greyed for now. I have just now used the camera in both iOS and Android live apps without any problems. Have you given the app permission to use the camera.

Glitch covered many times on Hornby 7K forum, power down app and loco and power up again, decoder will become linkable.
