Topic: Hair dryer fix how does it work?

Good evening/day

this is my first post and been reading thru the awesome topics here..
i bought a Wii-U in mint condition from a guy that said it was Blinking red ,did alot of reading on on fixes i thought the hair dryer fix was a bunch of rubbish but i was very wrong lol.

But i come in need of help something that goes against my understanding of electronics,
How does heating up the Wii-U cause it to boot?

Please if i can get answer so i can maybe do i permanent fix that would be much appreciate

Ps the console is spotless even still on 1.x.x Firmware

@Orry What's blinking red - the light on the console or the light on the gamepad?

Hope you didn't pay much for it. A console that doesn't work is not 'mint' condition in my book, however shiny it looks.

Hi bud thanks for the reply

no the console blinks red not the game pad

The guy probably talked about other thing. You call it "hair dryer", but its' actually "soldering station hot air blower". Google for how it looks like. There is no way hair dryer can help you to repair console.

To understand why hot air blower can fix you console you need to understand why it's broken.
There is no guaranty that you console is broken exactly in a way that hot air blower can fix it.

Now about what it can fix. Due to ecology care most electronic parts makers use lead (plumbum) free soldering. In time from constant heating and cooling such components loses electrical connection (that solder destroys if say it easy) and chip stops to operate. Most of such components we meet in PC motherboards (south / north bridges), in consoles and somewhere else.
So what hot air blower can do with it? It can HEAT it! That leadless solder will melt and restore connection. This operation must be performed on a chip that lose connection that way.

Words from me. This is very bad repair method. After half year it will break again. And to use it you must be sure what is broken and which way. Not just randomly heating every chip in your console.

P.S. Yea, chips has enough heating protection to stay undamaged from such heating... but it's still bad and should be made by proffi only.
