After I received a lot of my protech2u.com subscriber asking about service manual and how to repair dell e151fp LCD monitor, so I decided to write this repair note to you.

Last year until now, I had repaired many of this model LCD monitor. But most of the problem is no power or power on about 3 second then power cut off. Actually Dell E151FP Lcd monitor are made from Acer (Acer FP553 Chassis). Mostly, the component need to changed are same, when I first time repaired this model LCD I used about one and half hours to solve this problem. After I have these repairing experiences on dell e151fp LCD monitor, I just used about ten minutes to solve this type of symptom.

Below are the list of common defective component at the Dell E151FP LCD Monitor, Normally have the same parts are damaged, please take these useful notes.

Symptom: No Power or Power Come Up a while then no power

1) F601: 2A Fuse

2) C605= 68uf 400v (must change)

3) R615= 0.68ohm 1watt

4) Q601= SSS6N60A

5) R613= 1Kohm 1/8watt (value changed to 2.3Kohm)
