 ## Blue light repair
 
 I am subscribed to a few mailing lists and recently I came across this one here:
 
-[PA500 blue bypass light][1] - as
+[PA500 blue bypass light][1] - as the title suggests, it is about the blue bypass light.
 
 [1]: https://groups.io/g/diy599/topic/pa500_blue_bypass_light/110888256
+
+I am pretty sure the blue light lit randomly, I think I've seen it when I changed the
+PA500 operational mode back to full automatic.
+
+Anyway, the blue light was off for a while now and I wasn't sure what I should do with it,
+just ignore it or send the PA500 back for repair - none of that was a satisfying option to
+me as both would nag on my mind :D
+
+When I found the article mentioned above I knew I wasn't the only one with this problem and
+I joined the conversation and asked about the blue light when Oliver suggested to send me one.
+
+Now what?
+

+
+Right! I changed the blue LED last saturday (today is Sunday, 3 March) and I had the chance to
+test it today -- it is perfectly fine!
+
+{{< figure src="pa500-leds.jpg" caption="Soldering the LED with the LEDS attached to the aluminium housing so it will get the correct alignment to fit into the hole later" >}}
+
+I figured that out after I soldered the LED -- luckily I only had to push the LED a bit down to get it
+into the hole.
+
+Although I used a 1mm tip I thought I might got the board too hot already (350°C).
