Hi there all members Electro Tech,
I wonder if i can ask for your help regarding an electronic item,
It's a massager chair that had an Adaptor INPUT: 120VAC 60Hz 42W & OUTPUT: 12VDC 2A. I tried to connect this machine to UK Voltage Adaptor INPUT: 230-240V 50Hz OUTPUT 12V 1.67A 20VA. After that the machine stopped working and the Voltage Regulator (LM7805 MX511) was very Hot. So i tried to replace the Regulator with LM7805C & TS7805 but non of them work. I attached a photo of the circiut SORRY NOT VERY CLEAR PHOTO.
I really appreciated your input.
Have a nice holidays
Imad
