3- Capacitor Verification
Electrolytic Capacitor:
All electrolytic capacitor can be verified visually, values are written on the capacitor.
C29, C30 are 470uf/25V.
Ceramic Capacitor:
C1, C2, C3, C4, C5, C6, C7, C8, C9, C10, C11,C12, C13, C14, C15, C16, C17, C18, C19, C20, C21, C22, C23, C27, C31, C32,
C33 are 0.1uF capacitor randomly de-solder 2 capacitors and measure the value with the help of LRC meter and for
other just visually verify that they are of same package.
C33 are 0.1uF capacitor randomly de-solder 2 capacitors and measure the value with the help of LRC meter and for
other just visually verify that they are of same package.
C26, CE1, CE2, CE3, CE4
are 10uf tantalum capacitor randomly de-solder one capacitor and measure the value with
the help of LRC meter and for other just visually verify that they are of same package.
In the same manner check all the ceramic capacitors, if it is used in multiple location than only de-solder one
capacitor and other visual verified.
capacitor and other visual verified.
4- Connector verification
Check all RJ45 block connector used in main controller PCB (PT0012M), inside of all connector “GLG” should be
written as shown in the figure below.
written as shown in the figure below.
RJ45 Block Connector used in Main controller PCB
Make sure on the programming connectors of Main Controller PCB should be 2.54mm pitch as shown below.
