  • Power on for too long?

    I leave my TD20 module on because I'm getting the low battery warning and I don't want to lose my settings. Then I get a warning after about a week or two saying the power has been on too long, please power off, anyone else see this?

    Heard about it before... I'd worry about the LCD screen going out more than anything.

      I guess not all the settings can be saved to a CF card?

        Yeah, I guess I could do that. I just find it weird that you can't leave the module on forever if you want to.

          It may well be for the LCD. It doesn't have a screen saver mode so images could easily get burnt onto the screen. Also, there'll be one heck of a heat build up. I'd say backup and replace the battery asap! If you're quick enough with the battery, you shouldn't even loose your settings. If the battery is going, I'd guess your module is out of warranty anyway, so what've you got to lose?

            LCD doesn't suffer from 'burning'.. I don't really think that the LCD is going to cause you a problem at all.. Think of the products on the market wich have LCD screen which are on all the time.. Look at a digital watch for example. If anything the backlight might suffer, but I don't even believe that.. There are 1000s of commercial product which have a backlit LCD screen which are run for decades without problems.

            To be honest, I don't see why the unit can't be left on 24/7.. In electronic devices, its the constant switching on/off which does the harm in the first place not leaving it on all the time. Infact, I would guess that switching the backlight on/off regularly shortens its life more than leaving it on around the clock..

            The only thing which generates heat is going to be the internal PSU.. But again, I just can't see this being a problem.. Just look at a modern 'set top box' for your Satellite/cable/TV system.. They stay powered on and run forever without a very low failure rate!

            But thats just my opinion and shouldn't be taken as fact!

              Well, if Roland think its best, who are we to argue? Good point on the LCDs. I know the problem is more with older CRT displays. I know my laptop gets a bit dodgy after running for a very long time, though that might also be to do with the pityful amount of free space on my C drive atm!

              However, to counter your point about set top boxes, quite a while back we had a Freeview box that ran really hot and eventually killed itself. Funnily enough, it was made by the same people who were making Sky boxes at the time....... Also, in my student house, we have a BT Homehub for our broadband. That regularly crashes from the fact that it gets too how when we all try to use it at once. Seriuosly, over heating with 5pc's using the WiFi, what a joke! Bloomin useless pile of cattle droppings.

              Anyway, back to the original topic........

                I would agree with the suggestion to change out the battery (back-up first if you can for peace of mind, either by memory card or midi-to-computer). However, it makes me ask, how old is your TD-20? I'm surprised the backup battery would go out so soon, considering there are a lot of 8-10 year old TD-8's and TD-10's out there with the original battery still going strong. What specifically increases or decreases the wear on a backup battery? Perhaps your original battery was a bad one??

                  It's only a couple years old if that. Do I have to send my module off to Roland?

                    Nah, just undo the screws on the base, pop the battery out and stick in the new one. If it does it again, you might have the 'other' problem. If its less than a year old, you might have a more pressing issue.

                      I know there's a thread on this but where do I get the batteries?

                        It's fairly well documented that the vast majority of electronic failures occur during power up and power down - datacentres run 24x7x365 and so do recording studios (the big ones) to avoid such issues......
                        It would be really interesting to get Roland's take on this regarding the TD-20 - there might be some "hidden" reason for in in this module......

                            That sounds about right for me. How long has it been since you replaced yours? See this is what's wrong with e's, a's don't have this problem. Hahaha.
