No it don't
Expert:  Anthony_Infotech replied 2 years ago.
Well you need to check all the voltages coming out of it to the mainboard thats the one with all the input connectors on, what this will lead to is replacement of a board its either the power board or the main board that is the problem
Let me know if you can do this
Anthony

Ok on the right side of the power board you will see all the plugs with voltages stamped next to the pins of each plug let me know you see this
Anthony
Customer: replied 2 years ago.

Expert:  Anthony_Infotech replied 2 years ago.

Expert:  Anthony_Infotech replied 2 years ago.
You will have AC or DC on the meter you need to set the meter to around 30volts DC
Customer: replied 2 years ago.
It's ok
Expert:  Anthony_Infotech replied 2 years ago.
What is OK?you will have about 3 to 5 voltages to check?
If you don't know how to use the meter please just say
Anthony
Customer: replied 2 years ago.
Yea I don't my meter is newer then this much easier to use I have things to do right now ill worried bout it some other time or have it fixed
Expert:  Anthony_Infotech replied 2 years ago.
Its likely to be the powerboard you need to get the part number from the board and try www.shopjimmy.com for the board or google the part-number for suppliers.
