First and foremost, thanks for the fantastic tutorial!!

I took my laptop apart and put back together in about 3 hours this past Friday and everything still works (well, atleast what was working previous)

But, here is the problem.

I have the issue of the black screen on boot up. Everything works fine (hard drive, fans, all power lights, etc). But, the monitor stays black (or just simply does not power up)

Now, I have connected the laptop itself to an external monitor and everything works and boots up just fine. it is just he lcd that does not power up at all

My question: Before I go buying a new lcd or inverter, is there any way of checking to see if the inverter, cable or lcd went bad?? If there is no way, I might end up taking it to a local shop to see if they can test it for me

Thanks much

Greetings Laptop Tech,

First, many thanks to you for a great tutorial.
I was able to change the LCD screen on a Compaq F700 without breaking anything.

Unfortunately, after changing the screen and then (later on) the inverter, the laptop still doesn’t turn on. At this point, I’m at a loss as to what’s next in line to troubleshoot.

The screen is a brand new replacement and the inverter was pre-tested.

Any guidance to move forward in troubleshooting would be greatly appreciated.

Thanks!

jeff ellias,

my compaq presario f700-the display goes 3/4 bad with grainy lines, but If I wiggle the lcd it goes full.
I have ruled out the computer via connecting an external monitor.
How can I diagnose which one I need- the screen, lcd cable or inverter?

This is not inverter related problem, that’s for sure.
I really doubt that this problem is related to the video cable failure either. A bad video cable would affect image on the entire screen, not just 3/4 of the screen.
To me your description sounds like the LCD screen failure.

I have taken apart my Presario C700 to see why my display does not illuminate. I found a lose wire
(#1) which connects where the display and base are hinged, but cannot find where it should be connected. Also, I cannot find the connection for wire (#2) which had disconnected.
I am hopeful connecting all wires will fix the problem.
Can you direct me to where I can see pictures to guide me..

These instructions were very helpful and key to a successful LCD replacement on my Presario F700. First the tip on the cost and source of the LCD was very good. Mine was $87.33 with shipping and handling from ebay, and was specified specifically as compatible with the F700. The first site I got on a Google search wanted over $200. I got the matte finish screen, so this was actually an upgrade for me.

I was able to easily remove the screen bezel without removing the keyboard. Once the inverter and the LCD cable were removed I unscrewed the four screws holding the hinges to the screen and the screen came right off. The replacement went very smoothly. The only concern I had was that the top bracket was not included on the replacement screen and the screw holes did not align so I couldn’t reuse the old one. A sheet of paper included with the screen said that the top bracket was not really needed, so I went ahead and assembled without. The completed install seems very secure – so I don’t have any concerns.
