I don’t recall seeing a fuse on the board but will look again. Sounds like it will have to be replaced as well.

thanks,

Hello,
I’m a retired software engineer and chronic tinkerer. I started my formal education in Electrical Engineering and really liked the software/computing aspect of the curriculum so I ended up getting my degree in software engineering and have been in that industry for 35 years. I also enjoy building micro-controller (Raspberry Pi & Arduino) based IOT systems which has allowed me to bridge my software development knowledge with basic electronics interfaces. I hope to use the forum to expand my knowledge of electronics and help fill the gaps in my knowledge of electronics and...
