Having problems with your Dell E172FP 17" LCD Flat Panel Monitor ?

My monitor turns on momentarily but immediately goes to black streen. There is a padlock icon on the back don't know if this has been accidentally activated.


Answers :

It sounds like the their is a problem with the high voltage side of the tft this will let it turn on and sometimes display an image for 2/3 seconds then turns off, its a simple fix if you can use a soldering iron and you can find 4 transistors to replace them ( sorry can not remember the ones you need). But in relation to the padlock symbol on the back, this is a hole to attach a kingston security chain so it can not be stolen and not a password feature as other people have advised. Hope this helps
Sounds like it password protected to keep other people from using check your manual about changing that or call the manufactor usually going online wont tell you the information you need because of security reasons thell need all the info about it good luck
