Style mode LED turned off permanently

Hello everyone,
today I loaded some oriental SET into my PA2X-Pro device. It was running perfectly until I noticed a steady note playing in one of its containing styles. I decided to do a factory reset and load the SET again but after I did so, any of the styles are working anymore. Even the factory loaded styles.

What I noticed is that Style mode LED can't turn on anymore. The LED indicator for style banks 11/20 suffers the same problem. I am pretty sure that these LEDs are not burned. This has something to do with the problematic SET that I had loaded at first I guess.

I have even formatted my device using "Pa2X_Format.pkg" and then loaded the "Pa2X_os_res_v201.pkg" immediately afterwards, but still the LED problems are there and the factory styles do not work now and when I try to load some oriental styles via the USB or hard disk, they suffer from the same problem although the display shows me the style is running but I can't hear anything from drums, percussion, and automatic accompaniment. The upper right hand sounds are OK and I can play normally though. Interesting is that, when I stop the style, I can hear lower (left hand) chords when I play something.
I fell like I have lost my instrument now. I appreciate any help.

Kind Regards,
Manu

I just tested the song-play mode to check if I can get any sound out of it but it does not function either.

I checked all my audio output settings to make sure if they all get routed to Left+Right and everything, including drum kit output is set so.

Here is a video of how do I do the factory reset and it doesn't help at all:

Hi guys,

after replacing the burned LEDs, the device functions normally again. Under the youtube link above I have explained more.

I had To replace my blue LEDs twice since I owned my pa2x. First time through the official korg assistance, free of charge, but I had to stay 1 month without my keyboard. The second time, guarantee expired and old keyboard, I asked my cousin who is an electronic technician. He suggested me to change all the blue LEDs with red ones which are supposed to be much more resistant. I did it and since then it works perfectly. Please consider this option in case of future malfunctions. Simone.

Hello Ritchie_Blackmore,

The red ones that I have already replaced, I found in the company that I am working. I am an electronic engineer and we have lots of different components but I was lucky to find some because we have mostly SMD components and for this Keyboard I needed the very old 3mm LEDs.

The blue ones for which I am still waiting, I have ordered from ebay, below link and then select 3mm Blue LEDs.

I am not sure if they are appropriate ones because some LEDs have a bigger flat circle at the buttom. When you open the keyboard, you notice that the LEDs are surrounded by a black housing so that their light does not go through everywhere but towards top. This black housing has to cover the whole LED fully. This is what I noticed after I ordered the LEDs. Let's see if they match. If not, I have to look for new ones or as "simondrake" maybe I consider RED or even white ones.
Somebody has done a great job with white onse. You can check it out here:

Hello simondrake,

Thnaks to share your experience with us.
I got my blue LEDs today and I just replaced them. They are ordinary 3 mm LEDs and I had no problem to fit the black housing around it.

Moreover, I eventually noticed what was the reason of audio problems. If you are interested to know, please read the explanation underneath my own video.
