Korg Forums

Hello,

This Sunday we were practising with our band in our local. The temperature was low, i think 5-10º Celsius our lower.

Then the LCD screen of my brand new Korg TR 76 loose contrast. When i change from one program to another there's like the characters are overlapping themselves.

I raised the contrast to 28 or 29 and it solved the problem.

The sound was all right, all normal, but i was scared that the Keyboard was broken or something like that.

Do you think that low temperature can cause this or is a defect of the keyboard ? Should i claim Korg to replace it ?

As you may know, during the week i'm working outside my town and can't play my Korg until weekend, since then i will not see if it's allright or i have to raise another time the contrast.

During the week i play an old Yamaha to practise myself not to lose ability.

Thank you!

PS: We suffer cold of the winter in our local because the heater consumes too much electricity and if we raise the temperature it may blow the entire electricity system and then the light and all the things connected to electricity may be blown up (our preciate instruments and amplificators!).

Both my Korg keyboards act the same way when subjected to cold temperatures, but always recover when they warm up, so I wouldn't worry.

All LCD displays become "slow" in low temperatures - this is perfectly normal.
It'll go back to normal when it's warmer.

Curiously there is no Operating temperature indicated in both manuals...

...but electronics normally works well between 15°C and 35°C...

It must get pretty cold up there in Norway.

Thank you for your anwerss !!!

That solves my problem, i'm not concerned any more.

Fatalmaster, I'm not the real Mustis! Actually i live in Spain. But, despite the topics in winter there's so much cold here!

keep playing!

I know... just joking

I heard that it's not so good on the electronics when a cold instrument suddenly powers up. Plus any condensation that can build up on the electronics isn't good for it either.

The other day I had no choice but to keep my Triton in my car while at work because I had to drive direct to rehearsal that evening. The temp was about 9 degrees all day long. I had a stroke of genious and loaded a bunch of those hand and feet warmer packs that are suppose to last for about 6 or more hours into the case and then covered the case with a heavy blanket. When I got to the parking lot of my office I pushed my heater to about 80 degrees and let it run for about 5 minutesjust before I turned it off. i went out at lunch and fired it up again. The result?...don't try it....it didn't work...it was ice cold when I got to rehearsal.
