Sharp Electronics Repair
The branch of physics and technology concerned with the design of circuits using transistors and microchips, and with the behavior and movement of electrons in a semiconductor, conductor, vacuum, or gas
Circuits or devices using transistors, microchips, and other components
the branch of physics that deals with the emission and effects of electrons and with the use of electronic devices
(electronic) of or relating to electronics; concerned with or using devices that operate on principles governing the behavior of electrons; "electronic devices"
Electronics is the branch of science and technology which makes use of the controlled motion of electrons through different media and vacuum. The ability to control electron flow is usually applied to information handling or device control.
Make good (such damage) by fixing or repairing it
Put right (a damaged relationship or unwelcome situation)
restore by replacing a part or putting together what is torn or broken; "She repaired her TV set"; "Repair my shoes please"
the act of putting something in working order again
Fix or mend (a thing suffering from damage or a fault)
a formal way of referring to the condition of something; "the building was in good repair"
a musical notation indicating one half step higher than the note named
sharply: changing suddenly in direction and degree; "the road twists sharply after the light"; "turn sharp left here"; "the visor was acutely peaked"; "her shoes had acutely pointed toes"
Precisely (used after an expression of time)
In a sudden or abrupt way
Above the true or normal pitch of musical sound
crisp: (of something seen or heard) clearly defined; "a sharp photographic image"; "the sharp crack of a twig"; "the crisp snap of dry leaves underfoot"
Step 3 - Remove the OEM focusing screen
OEM focusing screen comes out next.
I talked to the sales guy @ Vetco - the last local "Mom and Pop" electronics store. He used to work camera repair and said that their standard practice is to invert the camera and shake the dang thing out.
No thanks. Here I used the dental pick to very lightly nudge the edges of the focusing screen. Again, it will swing down toward the mirror.
I am using the tweezers that came with the focusing screen. They are metal, and have very sharp edges on them. Quite frankly, plastic ESD safe tweezers are better, but all the ones in my day job are covered with sticky resin flux residue.
Messed up fan blades. (Repairing a broken mixer)
The fan blades are really chopped up!
I used a sharp knife to trim down the fan blades a little, trying to make them as smooth as possible.
