Can you hear any fan or drive sounds? If you don't hear anything at all when you try to turn the laptop on, no little LED's light up, the problem almost certainly isn't related to the hard drive. So if you don't have a live screen, start with the LCD troubleshooting flowchart, and if you don't have any activity at all, start with the power troubleshooting flowchart. Even if the hard drive has failed at the electro/mechanical level and won't spin up, this wont prevent the LED's on the laptop from lighting up, or the LCD from displaying the BIOS information and complaining about the lack of a boot device.
Be more specific. Turning off when? What happens when you try to turn it on? When you have the power cord plugged in do you see any lights? When you press the power button do you hear the fan running, hear the hard drive running, see anything on the lcd screen, hear the cd drive Click once, see the light on the cd drive drawer turn on for a second or two when it clicks, hear any beeps or blinking lights?

Mine also would not play back on any of the channels but would record. The problem was on the lower board, capacitors C105, C205, C305 and C405, all are 220uF, rated at 10V - on a 9V machine! All four went leaky, which meant that the op-amps each were connected to got a bias which drove the output to 8.5V and no output. I replaced all four capacitors with new ones rated at 25V and it works again!
probably the amp section- I am working on a STVG-700 right now, the audio amp is mounted on the lowest circuit board in the case, includes the power supply except for the transformer. There are fuses mounted on this board, with luck that's all that blew on this. I know this problem is months old, but if you're like me and didn't get it fixed quickly, it's still sitting around somewhere...
It appears that the display has gone out in the computer. Sorry to say but you have two options.
1. You can take the computer to a computer repair shop and get a new motherboard put in.
2. You can go buy a new computer.
They both will cost about the same but it is more worth it to buy a new computer in my opinion. The reason i say this is originally i was thinkning that the LCD monitor in the laptop may have gone out but if it is not showing anything on an external monitor than the computer is not putting out any display at all.
If you can hear your windows loading but no display, try plug-in an external Monitory on your Laptop. If you can see the display on the screen with this monitor then maybe your LCD or Inverter is broken, or try turning on/off the switch for External Monitor and LCD Display on your keyboard. Usually by holding the "FN" key on your keyboard and look for the LCD/VGA icon on your keys then press it.
