There are usually 3 types of connectors , 1 you just pull the cable out, 2 you have to flip up the top of connector to open the socket to remove the cable, 3rd you push the 2 side tabs toward cable on the connector where the cable enters the connector.

How do I fix the constant flickering of the screen?


Take the lcd assembly apart, and disconnect and reconnect the ribbon cable on the back of the lcd. Also disconnect and reconnect the other end of that cable. If that doesn't fix it, disconnect and reconnect both cables that go to the inverter board (it's the small circuit board inside the lcd assembly- example in picture below). If still no good, then you probably need a new inverter board. Call HP and get a phone number for one of their parts suppliers. Inverter boards are cheap ($10-$20). Even if it doesn't fix it, it doesn't cost much to try. If still no good, then take it to a service shop.

Hope this helps!

I have a dell e198fp monitor con nected to a dell latitude d400. Got monitor from daughter who said monitor was working then went black and stayed same. I get a blinking green power button with a black...

I suspect you will find that there are bad capacitors on the power supply board. If you aren't handy with a soldering iron, however, I would not recommend this repair. It can be easy to permanently damage things. If you aren't afraid of that, however, give it a try.

There are two that I have found that typically fail (680 microfarad, 16 volt). They usually "bulge" on top after failing. I have found that the replacement value doesn't seem to be too critical. I wish I had written down the actual designators for these caps (maybe next time I repair one of these monitors).


Once you get the bezel apart and get down to the metal shielding, slide the shield on the right hand side to remove (arrows pointing to each other). There will be four connectors underneath this shield to power the backlight. Disconnect these four connectors, paying close attention to where they were connected.

Disconnect the small ribbon cable on the other side connecting to the front panel controls...There is a small black tab that will flip up to allow removal of the ribbon cable. CAUTION! THESE CABLES ARE DELICATE...DAMAGING THE CABLE OR THE CONNECTOR WILL DESTROY YOUR MONITOR.

There are four screws holding the power supply section to the LCD itself (two on each side). Once you remove these screws the rear shield (and power supply section) will start to separate from the LCD. There is another ribbon cable between the power supply section and the LCD panel...AGAIN...DO NOT DAMAGE THIS CABLE OR CONNECTOR! Squeeze the two black tabs on either side of this connector to remove.

You should now have the power supply board exposed. Remove the screws securing the power supply board to the shield. You will need to disconnect the connector attaching the AC power inlet to the board in order to access the top side...

The failed capacitors should be readily apparent. Replace them, re-assemble and test.

That's it

How to replace lcd screen? where to buy?

It's probably cheapest to buy a broken "donor" camera off ebay etc. LZ7 is a fairly popular camera and you're eventually bound to find one with e.g. broken lens-which you could scavenge for replacement LCD.
Swapping LCD on LZ7 is relatively easy-undo the screws holding the back cover (make note which screw goes where as they are not the same), then carefully lift the cover a bit just to see two ribbon cables for the LCD. Disconnect both ribbon cables by carefully prying the "black bits" on the connectors open and sliding the ribbon cables out(Not the best description but it should be obvious once you see them). Once you separate the back cover, remove the screen itself by undoing the catches which hold it onto the case.
Hope this helps-
Good luck,

Blank screen

You can open the camera and check to see if the LCD ribbon cable is still connected to the main board. If it was dropped they can become dislodged. There are two cables the smaller one is the most sensitive to coming loose. When disconnecting and reconnecting the ribbon cables, make sure you are careful while lifting the tabs that hold the ribbon cables in place they are hinged and will lift up and the ribbon cable will slide out. Note the large ribbon cable feeds through the camera to the front main board. Hope this helps

Does the camera take pictures?
If you take the camera near a lamp, can you just about see menu items on the LCD?
If so, it's possible that the backlight ribbon cable slipped out of the socket. To check open up the back of the case and carefully lift it up a bit just to see the ribbon cables. The narrow one is used for backlight. Try to disconnect it (open the tiny black flap in the connector) and connect it again (close the black flap). Have a quick look at the connectors on the ribbon cable and make sure they are clean. If it still doesn't work I'm afraid most probably you have a faulty backlight and will need to replace either the whole LCD (easy) or just the backlight (fairly fiddly job). In any case, you'll probably need a donor camera (ebay ;) to scavenge for replacement LCD.
Good luck,

These units have a problem with the base unit going bad, often caused by a power surge. The symptoms are, in addition to the above, none of the buttons on the base unit work. I found a partial work around that gets all the lights off and the system working, but the buttons on the base unit still don't work. Not really a problem as the answering system still works and you can retrieve your messages from any remote by pressing Menu and then the LCD button "Select" You have to be a tear-it-apart-type to try this but here is what to do
1. With a small Phillips screwdriver, remove the base from the cover by taking out the 5 Phillips screws.
2. Next unplug all lines to get the cover and base separated.
3. Locate the flat ribbon cable connecting to a connector on the edge and disconnect it by pulling out (away from the connector) the two locking tabs.
4. Plug in the power and reinsert and relock the ribbon cable
5. Check the lights. If most of the lights are off unit is ok and you can disconnect the power, reassemble, and reconnect all wires.
6. If reconnecting the power causes all lights to go on again, you have the same problem I had, for which the solution is tougher and only temporary
7. Repeat all of the above steps but do not disconnect the power when separating the cover from the base. This will make it impossible to completely remove the cover from the base, but you can tilt the cover up enough to be able to access the ribbon cable to disconnect and reconnect it.
8. Lights will now stay on as long as you never disconnect the power or have a power failure, in which case you have to repeat the above. I wound up hooking up mine to the same outlet strip I had connected to my uninterruptible power supply (UPS).

LCD Screen goes blank after opening up

I actually have several of these cameras and have seen this happen many times with this model. The ribbon cable that goes from the body to the LCD tears in the same place in all of my experiences. If you look at the hing area, you can see the black coating on the ribbon cable between the body and the LCD. The top edge of this cable tears right where it enters the LCD component. If it works when only 1/2 way open, it's just a matter of time before it totally stops working...the damage has already begun. A replacement LCD runs >$100. Instead, I search e-bay for parts cameras. Just make sure that the description doesn't say that the LCD is bad.

Taking apart the camera isn't all that hard. Start with the e-bay parts camera just in case something goes wrong. Take off the lens cover (the lens actually stays attached to the camera for this entire fix) by removing a screw on the bottom, one just under the eye piece, one inside the LCD door area (near the top), and one inside the tape area...the one closest to the front of the lens. Then, the lens cover slides forward. Once you get it moving forward, extend the eye piece and the lens cover comes right out.

The 2nd step is to remove the LCD. The easiest fix is to remove the entire left side (LCD and SD flip cover). This is done by removing the 3 screws on the bottom (careful, 1 is smaller than the other 2), the screw in the battery area, a screw near the front of the lens, and 2 screws near the top (one above and 1 below the lens). Once the left side is free, tip it forward, exposing the 2 ribbon cables. The larger one is the LCD. Disconnect it by simply flipping the grey bar where the ribbon cable connects to the body up. The ribbon cable should come out with no effort. The other, smaller ribbon cable is the speaker and the "LCD is Open/Closed switch". Be careful with this one. Hold the white connector in place against the body (I apply pressure using a small, flat screwdriver). Pull the ribbon cable out of the holder at the body with your fingers (it should require only a moderate amount of force). If the white cable connector comes off with the cable, you're in trouble...the wires are extremely thin and difficult to get back in the right place...but it can be done.

Once you've removed the left side portion, do the same with the good LCD. Reconnect everything in the reverse order. I use a small needle nose pliers to put the small ribbon cable back into the connector. The larger one just slides in with little to no effort. Lock it in place by tipping the locking back back down. Once you've connected these 2 cables, you can carefully put a battery in and test that it works. If all goes well, remove the battery before continuing to put it back together again.

When you're done, put the parts camera back together again and keep it. You may need it for the lens assembly (I've had grease inside my lenses at times and the front lens can scratch easily, so a replacement is good to have around).

I've tried replacing just the ribbon cable, but getting it out of the LCD isn't worth the effort since finding a good cable usually means that you've also found a good LCD for the above proceedure.
