You can buy a lead for about £10.
Close the straighteners and tape together.
There's a rubber band by the flex, roll it off.
Loosen two small screws with a fine crosshead screwdriver and remove the flex holder.
Simply pull out the whole flex from the circuit board and replace with new one.
Put the appliance back together and you're good....till the next time.....it's a common fault on these.
