Re: e153fpb brightness goes down in 2 secs

Fuse PF751 was tested and found to be good. Thank you Bobdee, the link with schematic helps (how did I miss that - my bad - sorry). I have what I need, to investigate. I will post what I find.

Re: e153fpb brightness goes down in 2 secs

PCBONEZ and FIXITNOW - thank you for your response. The only fuse F601, I could find, is good. It was marked as T2AH/250V, near the power connector CN601. Are you sure there is an F1 fuse and an XA connector? Any other suggestions please?

I have a 15" Dell lcd monitor e153fpb that I am troubleshooting. Turn on the monitor, display looks fine for 2 seconds only and the brightness goes down to almost none. But display is there it is very faint. Turn it off and on, again it looks bright for 2 secs only. Same thing happens when I connect to my laptop and keep toggling from laptop to monitor. Every time the display stays bright for 2 seconds only. Did anyone saw this problem?

I opened the monitor and apparently all components and solder joints look fine. Does anybody have the schematic? Any suggestions to identify...
