Inspected tv and it has 206 watchdog errors..the tv has already had a new main pcb which I think was faulty, the original fault was tv freezing and not running wifi and control buttons not working..I tested all that today and they are all working, but now the tv is switching off after 5 minutes.
Although I told the customer that I think a new motherboard will repair it I'm not 100 percent as it's very rare for samsung to send us out faulty goods, and because of that I'm concerned another main pcb may go faulty overtime due to something else in the tv causing it to fail.(all fault errors point to main PCB though)
The customer doesn't want another repair as this has been going on since august and had 3 trips to her house and she is uncomfartable having more people into her house during these covid times.
Please contact customer and explain the next steps to her today please as she has an appointment tomorrow..
That was my last email today.: 50 quid into the back pocket
