The infromation I have found states that the transistors responsible for this prblem are located on the power inverter board. This is the larger of the two main circuit baords, you know the one the power cord plugs into. These components are located on the side of the board farthest from the connector to the other circuit board near the center.

The transistors are Q739, Q740, Q759 and Q760. They can be obtained from Digikey, check thier website for part# 497-2574-5-ND. The transistors are $1.16 each. Information I found was located at the following link. http://www.dellcommunity.com/supportforums/board/message?board.id=dim_monitor&message.id=53441

The parts I found based on the information that is provided in that thread.

does anyone know details of how to repair the common problem with the dell E173FPC, i have found fixes for the E173FPb but the E173FPC inverter board and components are different,

many thanks

Hi, good luck on this repair, as the thread you posted shows, several of the people posting had the unit fail again right after repairing it. You have probably an 80% chance of the
unit failing again within a few days or hours, keep that in mind if you plan to do these repairs for others or repair units for resale. Prepare for warranty processing

Regards,

Mike
