Please follow the diagnosis outlined in this article to check whether the backlight lamp or the inverter board are the root cause of the problem or not:

If you connect the external monitor & nothing is displayed on it, then this means that both the backlight lamp & the inverter board are fine. The main indicators in these cases are the sound, and the hard drive LED on the laptop case. If the laptop sounds just like it always does for a minute or two after being turned on, it means it's going ahead and booting the operating system, but the video processor or part of the motherboard circuit for video output has failed. If the laptop just sits there and beeps when you turn it on, or if you hear the fan but not the hard drive chuckling with its active LED flashing away, it means the laptop isn't getting as far as trying to boot the operating system. While this could be due to any number of hardware problems, the most common and easiest to
troubleshoot or repair is RAM failure. If your laptop has two RAM modules installed, try booting with just one and then the other in the primary slot. If your laptop only has one RAM module, you might consider buying one online from a site with a good memory selector, like

Power on screen blank.. fan on

Did you hear a sound beeping. If you can hear a sound beeping it is a RAM problem. But if there is no sound beeping that is a processor problem. You can disassemble or remove the processor and clean make sure that the processor fan is spinning so that it will control the temperature of the CPU to avoid overheating.

My compaq laptop F500 has black screen when power on

That sounds like a power supply problem. That would be the first thing I would check. If it was the processor, you would have heard a long beeping sound or if it was the memory you would hear about three 'annoying beeps'. The main reason you indicated there is no display on the screen and that the fan spins for a few seconds then shuts off, would hint that power is not going to the mother board long enough to spin the processor or cooling fan. Hope this helps :)

Laptop Won't Boot


Vaios are prone to faulty Ram ( memory Slots ) The only suggestion i can offer.
Is to remove and re-seat the CPU. this ocassionally solves the problem. if the laptops been dropped or banged. the cpu may have worked loose. but you,ll be looking at either ram or processor. failing this you can assume that theres a motherboard fault.

Thankyou For using Fixya.
