Having problems with your Sony VAIO K45 Notebook ?

Screen blacks out

\015 If the monitor is swiveled at a certain angle, the screen will black out or flicker really bad until I try to swivel it slightly at a different angle. Once it blacks out it's tough to get it back on without having to restart. Can this be fixed??\015

Now let's discuss what we\015\012should do when the laptop seems to be booting up without problems, the\015\012hard drive spins appropriately, and we even hear the welcome sound of\015\012the operating system, but we have no display on the LCD panel.
The easiest and most foolproof method for testing your LCD screen\015\012is to hook up the laptop to an external monitor. If the video output on\015\012the external monitor looks fine, this means that the problem is with\015\012the video connector, with your LCD panel itself, or with the circuitry\015\012that turns on the LCD.
What do we do? It all\015\012starts with disassembling the notebook. Find the video connector on the\015\012system board (if the video is integrated on the motherboard) or on the\015\012video card that is attached to the motherboard. Try re-connecting the\015\012cables. You may as well locate the display connector on the back of the\015\012end LCD panel. Re-seat that one too. This way you can be sure that the\015\012problem is not related to connections.
image002.jpgEvery\015\012now and then the switch located on the system board that turns the\015\012backlight of the LCD on and off can become stuck. If this is the\015\012problem then your LCD never powers on. There's a little switch that\015\012detects whether the screen of your notebook is open or closed. That's\015\012the one we're talking about. Try to push it down and hope it gets\015\012unstuck.
Disassembling the laptop to unstick\015\012this switch is an option, but sometimes you can get away with not\015\012taking it apart. Try lightly hitting that plastic switch. But\015\012wait, this isn't the only possible cause, unfortunately. Re-seat the\015\012other connectors and cables that are present around the LCD panel and\015\012the video on board (including the inverter).
All\015\012of the aforementioned can usually be fixed, but let's not forget about\015\012the screen itself. Sometimes the screen can become defective. Here\015\012we'll enumerate a few scenarios where the screen has gone bad and must\015\012be replaced: lots of vertical lines or bands appearing on the screen;\015\012half of the screen works fine but the other half stays either black\015\012(blank) or really white; the output on the screen looks blurred and\015\012changes to different patterns; and so forth. These are almost always\015\012signs of a defective LCD panel.
However, if the\015\012output on the screen is nothing but garbage, such as incorrectly placed\015\012special characters, shadows around the characters, unknown randomly\015\012placed marks of different colors, distorted or ugly-looking geometric\015\012patterns, or tiny little white dots all over the screen, then these are\015\012almost always due to the system board or the connection between the LCD\015\012panel and the video card. Re-seat the connectors.
All\015\012in all, these are some of the most common hardware failures.\015\012Nevertheless, before we finish this part, let's name some of the\015\012others that will be covered in the second segment of this guide, along\015\012with the promised system instability troubleshooting strategies. These\015\012include clicking noises coming from the HDD, which is the well-known\015\012symptom of a dying HDD. Thus, back up your important data as soon as\015\012possible and order a replacement. Overheating is also discussed\015\012thoroughly.

Hope it may helpful for you

You need to re-seat the connector between your monitor and the system board. i would recommend that you take it to a tech since laptops are very delicate on the inside and just the static from running a hand through your hair is enough to completely fry one.
