Dell 2007WFP Constant On/Off

Re: Dell 2007WFP Constant On/Off

Hi, this sounds EXACTLY like my problem with the same monitor.
I can say for sure that its Power that keeps cutting in and out. the power LED does not go orange, it goes from green to off, it cycles like this over and over. approximately 30 seconds On, then 5 minutes off. splashes the DELL logo, and we start all over again.

it looks like nothing has happened with this post lately. I'd like help!!

Re: Dell 2007WFP Constant On/Off

thanks for the help, thought I had an easy one.

When the monitor goes off, I meant it goes into sleep mode. When it constantly goes on and off, I meant that the screen goes off and the next second Dell logo pops out. This loop continues with a random interval.

Attached the pictures.

What do you guys think and where should I start?

Thanks.

Nice picture! That's glue, and there's probably a component underneath it. Those Elite capacitors are a known bad brand, but probably not to blame for the monitor not working.

Please give more detail about what the monitor does. When it goes "off", does the power light stay on? Can you see a dim image by angling a flashlight or sunlight at the screen?

Please take pictures of the rest of the boards, top and bottom, and post them.

Attached the suspect.
Is this glue or leak?

Thanks for the reply.

White is usually glue holding down components. A leak will be from the top vent or out the bottom, often rust-like or black. It's best to post high-quality pictures of your boards. Attach them with the Manage Attachments button.

Nevermind :P
I actually found a cap with leaks (white stuff coming out). Should've done more research before posting.

Hey Guys,

This is my first post here and I have to say this site is quite awesome for the amount of information I could find.

To my problem, I have a Dell 2007WFP and it is constantly turning on and off. Occasionally it works for a couple minutes without flashing and sometimes it stays in sleep mode for a while then comes back and so on.

The pictures of the boards are similar to here

To you experts, what are your thoughts about this problem? If a cap is bad, how can I find it??

Thanks!
