The following disassembly guide will explain how to take apart a Sony Vaio PCG-K series notebooks. I created this guide while taking apart a Sony Vaio PCG-K25 notebook but I think you can use the same disassembly steps for all notebooks in PCG-K line.
The main reason to open up the laptop was replacing broken power jack. Proceed disassembly on your own risk.
Update: I just created a new guide for Sony Vaio PCG-K series laptops. It explains how to remove and replace LCD screen with inverter board.
Before you start laptop disassembly, unplug the AC adapter and remove the battery.

Hello, this site was very useful in my fixing the broken power supply jack for my PCG-K45 Vaio, only I improvised a little and took liberty to install a flexible hard wired jack through the existing jack hole after I pulled it out with Pliers, took the old harness out an spliced the new one in, worked like a champ!!!! TAKES the strain off the Jack, TOO! Only problem is the cooling fan races like a bat outa HECK >and wonder if you could do a segment on how to relase the fan and apply new heat sink compund on the CPU fan assembly..GREAT SITE!!!!

Ash,
You said the laptop screen lights up (without video), so the backlight lamp and inverter works fine.
Did you try reconnecting cable on the back of the LCD screen? Maybe you accidentally pulled if from the screen while taking apart the laptop?

Tried it, and examined for damage, but saw none. Carefully reconnected the cable to the motherboard seating as deep as it would go without force. Looked uniformly inserted around all sides. Still the same as before. Before I ever took the laptop apart, the screen worked fine. Could I have damaged the cable or the lcd inverter?

Ash,
Try reconnecting the video cable. Maybe you accidentally pulled the video cable from the motherboard?

Hi,
I ended up unseating my cpu when “fixing” my frv27. I have now replaced it and the computer starts up and works fine except for the video. The laptop monitor lights up a bright black (has power) and flashes during boot up, but never shows any information. An outside monitor works fine and shows the computer boots normally. Any suggestions would be greatly appreciated. Thank you.

mario,
Maybe it’s not necessary to replace the connector itself. You’ll have to find a technician who can reflow solder joints on the connector.
By the way, maybe you can put something under the hard drive, for example a piece of pen eraser, so the hard drive is lifted a little bit and the connector makes a good contact with the motherboard. Maybe it will work this way? Can you close the hard drive door when it’s lifted?

A++++++ Write-up. Fantastic photos !
I have a computer business. I ordered a keyboard and did a search. Came upon your site. Replaced keyboard and everything works perfectly. By the way. It’s a lot easier disconnecting the bezel ribbon connector at the bezel instead of reaching down to the motherboard. But if disconnecting from the mother board use the small end of a small paperclip opened up as a hook to lift the tab on the connector enabling removal of the ribbon cable. It also helps to keep the tab up as you insert the ribbon upon re-assembly.
Thanks again…. Bob

Mario,
I really doubt it. In most laptops the hard drive connector is soldered directly to the motherboard and I don’t think that you can replace or resolder the connector yourself unless you have equipment and skills for that.
