Screen whites out on boot up

Remove the battery and open the case. Look inside the computer with a flashlight to see if any of the capacitors are busted or leaking from corrosion. The capacitors look like little battery towers, but they are not as tall as the AA or AAA batteries.

If the capacitors are bad, your computer goes bunkers.

step one, big battery out? skipped that?
step 2, a good power pack , that means 19vdc on those 2 pins.
bingo BIOS screen now work ,yes?
step 3, try an external VGA screen at the P15 VGA jack there
screens work now (BIOS first) yes/no?

remove DVD, drive
and all USB devices
there booting with only 1 memory stick. (got more?, try each 1 by 1)
black screens of *****'.

the lack of flash codes, Implies Power pack is dead. or CPU overheated, and selfshuts down. that fan going dead tells
me the power park is dead.

Do you have another monitor to test your computer? Looks like a surge went into the computer display and damaged the video card.

Did you switch displays to the external video? Try hitting the Fn key and whichever function key at the top of the keyboard has a little TV screen icon over it at the same time.

your battery may be getting to weak to work.
try booting without the battery.

This is a known symptom of a failed power supply board. Here is a repair guide for this unit that shows how to dis-assemble the unit and then what to look for and replace to rebuilt the power supply board and bring the monitor back to life.

there is a hole on the back usually goldish inside take a pen push it in there hold for a couple seconds and press the power button

I fixed it!

The Westinghouse LCM 22w2 has bad capacitors on the yellow power supply board. This is a common problem plaguing motherboards and LCD flatpanels that use capacitors from Taiwan. If you know how to solder, or know somebody that can, it's actually a pretty easy fix. Take out the yellow circuit board on the inside, write down the specifications for each of the capacitors (the cylindrical things) go to the electronics supply store and get the replacement capacitors. You can go over the voltage specification (not under), but keep the capacitance value matching. Replace one at a time. Go to www.badcaps.net for advice, tutorials and training on doing this. *You really should replace all the capacitors*, but the very large one next to the power plug I did leave on the board because I couldn't find a match. To my delight, the white screen of death went away and it was working as new!

I saved a ton of money fixing this, it's definitely worth learning how to solder to do this.

this is normally motherboard or powe side problem check your motherboard
