Hi Everyone!

Well, after reading everyone of these hallowed pages, I am still non the wiser as to what to do.

I have two Sony Vaio's -

1) VGN-FW41E/H
2) VGN-BX61MN

Both showing the exact same symptoms.

These being;
BLANK SCREEN,
CD/DVD-ROM Spinning (and trying to read when disc inserted),
POWER LIGHT ALWAYS ON,
BATTERY LIGHT FLASHING WHEN AC PLUGGED TILL BATTERY CHARGED
CPU GETS HOT AND FAN KICKS IN
NO EXTERNAL DISPLAY

Like so many of you in the past I have tried the following

1) Tested RAM/CPU/HDD on good systems (all OK)
2) Tested DC adapter (19.5v as per Adapter)
3) Replaced CMOS batteries

Nothing works!

One thing I think may be part of it (I know for certain with the FW series) is that the BIOS had been updated due to VT update for the CPU. Could it be a bad flash? :/

I am OK with component level repairs, but I am at a complete loss as to where to start on these!

So any advice! Any suggestions! There is power there, its just tying to get it to blooming well work!

Answers on a postcard lol ;)

Often the ram can cause this problem, though you should hear beeps from an on board speaker if that is the problem.
Install only one stick of ram, then try the one stick in each slot.

Have you tried to use an external monitor?

I flashed and ruined the bios on a desktop pc before. i don't think it would even post. This would show up immediately after the flashing of the bios though.

RAM was my immediate thought as well, often on laptops one of the RAM slots will be the primary slot, which must contain the first RAM chip, when youve had a laptop for a while the regular knocks and bumps can damage the support struts which hold the chip in place, it is possible that the chip isnt seating properly and thus the laptop fails to start.

Hi Guys!

Thanks for getting back to me.

Yeah - I tried both on an external monitor and also tried reseating the RAM on both - still no go.

I have discovered something though. A small issue of grounding.

It looks like both these systems are shorting out! I can't beleive I missed it, so I am currently testing the power circuit to see if I can find anything.

Keep the ideas coming though!!!!

Thanks ;)

Hmm grounding? That's quite a tough one to check out.

I would just take it apart and replug everything, I think it's easier. The problem is finding guides on a specific model if you're not cocky enough to do it yourself.
