The power supply is probably going bad. A repair shop can check it for blown capacitors and possibly a burnt Zerner Diode. Should be easy to repair or replace the circuit board.

I power on my lenovo g55o, the power light come on, the battery charging light and the hard drive blinks for a couple seconds and goes off, but the monitor never lights up


You can try switching off computer, unplug the ac adapter, then the battery. When all power source are removed, hold the power button. Then put the battery back on then try switching the laptop back on.

Sub won't stay powered up

Monitor problem


You need to figure out if the monitor is faulty or if it is due to the power in your house (not likely) or the fault of the computer.
  1. Try the monitor on other power jacks.
  2. Try the computer on other monitors and see if you get the same response.
If it seems to just be the monitor then you will most likely have to have it serviced or replaced. Is it still under warranty?

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
