The biggest issuse is that the circuit board appears to be cracked or have a dry joint. You have to apply alot of upward pressure on the power connector to get it to come one and even then it's intermittant at best.
I've checked all the wiring and connections and the plug is fine, the problem is either with the connection to the socket, or the PCB.
Any ideas as it is going to cost me a fortune to return it, I live in the UK.
Secondly, can you change the 1" display to English? I assumed it was only in Korean but someone on here has it in English and said it came like that.
