Touch screen dim and flickers (Korg Trinity- original)

[Yawar94]

Hello everyone. I hope all is well here.
I'm new here.

I'm having problem about my Korg Trinity. The touch screen is dim like faded and it flickers when i change the preset. I've encountered this problem today. Last i used was like a month ago and screen was perfect, all colors and everything. The synthesizer is overall very well working regarding sounds and other technical stuff. I'm just worried about the touch screen. Also, wanted to add my room gets very hot in summers and synth is in my room. Maybe the temperature has got something to do with it? idk.

Please help if someone has a solution and information regarding this. Thanks.
