So a while back my lcd screen cracked (accident). i made due for a while until my gf talked me into replacing the lcd screen. i ordered the part from pentax and took a gillion screws out of the camera to get down to the screen mounts. turns out there are two connections between the screen and the camera, (1) a wire that has to be soldered (i guess this is a power supply) and (2) a ribbon cable that has to be clamped into place (i guess this is the video feed). so i took the old screen out, soldered the wire to the new screen and tried to get the ribbon cable in place. thats where i think the problem lies. i have the ribbon cable in, but i don't think all the way. i put the camera back together, power it on, screen turns on (i have power), but no image at all (before there was a messed up crystalized image). i can still take pictures, i just can't review them.
any ideas? i think the ribbon cable is my issue, any tips on how to get it in the clamp? the close quarters really made this hard.
thank you in advance.
Ok, having had the same problem as yourself, I can tell you that when looking at the lcd, the ribbon cable on the bottom left hand side stays flat and plugs into the light blue clamp (that is hinged and lifts up) the ribbon cables copper contacts face down onto the bed of copper contacts exposed when the blue clamp is opened. Hope this helps.

Re: replaced LCD but no image appears
There are several different types of flex cable clamp arrangement. In some the clamp goes over the cable and others underneath, it is easy to forget which way the cable went! So check how the cable is seated and look carefully at the connector. Often if the cable goes over the clamp it will be grooved. Also when you removed the cable did you slide the clamp out or just pull the cable? It may be that the clamp is actually preventing the cable from being replaced. I use a pair of fine nosed tweezers to push on both ends of the clamp to release it. CAUTION! the clamps are very fragile and once broke virtually impossible to repair.

If you can see the images on the screen very faintly when you shine a flashlight on the screen, then your problem more than likely is the LCD Inverter. The LCD Inverter costs less than $10, but you will have to disassemble the lcd screen to get to it.
I'm sure you know that you can attach an external monitor to your laptop and hit the FN key and hold it while you hit the correct F1 thru F8 key that will display the image on the external monitor? This could be a solution until you get the inverter fixed.
Now a dishonest repairman will take advantage of you if you take that laptop to them talking about the backlight is going bad. He'll simply bill you $300 and tell you he had to replace the LCD Screen which houses the back light an most times it's easier to replace the screen then fool with the backlight. And in your case all he would do is replace the lcd inverter that sits under the lcd screen and is covered by the strip at the bottom that goes around the lcd screen.
If your screen works in playback mode, the screen and flexible circuit boards are intact. To shoot an image using the LCD screen you must first activate the "live view" function in the setup menu, and then press the live view (Lv) button to view your image on the LCD.
Is the LCD monitor broken with a cracked screen or is it just not displaying an image?
If the screen is cracked then it needs to be replaced.
If there is no image on the screen and it is not physically broken then the fault could be an inverter problem or a faulty CCFL lamp.

Hi there The best way to determine if its the inverter thats burned out is to look very closely at the screen, if you can see a very faint image then its the inverter which has blown or the connection has worked loose.
1. That can be connection related problem. I
check connection between the video cable and the LCD screen, try
reconnecting the video cable. It’s necessary to take apart the display panel,
unplug the video cable from the connector on the back side of the LCD
screen and then plug it back in. In some cases reseating this
2. If reconnecting the video cable doesn’t help, here’s what I do in
this case. While the display panel is still disassembled, I turn on the
laptop and wait until image appears on the screen. Then I move the
video cable a little bit without touching the LCD screen. If
moving/touching the video cable affects image on the screen, it’s
possible that there is a problem with the cable. Apparently there’s a
short somewhere inside the cable. In this case, replacing the video
cable may fix the problem.
3. If reconnection the cable doesn’t help and moving/touching the
cable doesn’t change image at all and the only way to get better
picture is moving/touching the LCD screen itself, apparently there is a
problem with the LCD and it has to be replaced.
