To-do

SOT89-3 transistor or power regulator Q701 (labelled ‘DC’) is fried. Must find a service manual or a donor unit with a working display to determine the specifications of Q701.

• The SMD components marking codes database – Starting with ‘DC’
• DC SMD marking code, cross reference, replace part, description Pag. (6/14)6
