Having problems with your Sony VAIO® VGC-LS37E PC Desktop ?

I have the EXACT same problem

\015 Has anyone found a solution? Or, know what the source of the problem is? Is it a faulty Display Switch? I chatted with Sony online help yesterday and they are useless. Any techs out there know what to do? this is an All In One unit. Any suggestions?\015

Answers :

First of all you have to determine if the problem is the GPU\015\012(graphics processing unit) or a possible bad connection on the inverter. Either way this is a hardware issue.

To\015\012check this you will need to plug an external monitor to the laptop and\015\012use the keyboard toggle to switch screens, usually its hold down Fn and\015\012press F6 or the F key with a monitor icon on it.

If the external monitor comes on and displays the boot or Windows logo's then the problem maybe the inverter or bad cable.

To check this remove the screen bezel (plastic screen surround). At the bottom of the screen you will see an\015\012elongated piece of circuit board with wires coming from either end\015\012covered by frosted plastic.
That is the inverter, check the connections on the inverter (both sides) and power the laptop up to check the display, to remove it\015\012gently pull the plugs from each end and remove the screw from the\015\012middle and pull the board away.
Look on the back of the inverter itself for a copper coil, if you\015\012re-solder the solder points around the coil you may find it works again\015\012as components that suffer from extreme heat the solder joints dry\015\012causing bad connections, re-floating the solder solves the problem in\015\01290% of cases.

If none of this resolves the problem sending the unit back to the manufacturer will probably be a good idea.

Good luck.
Did you get your computer back from Sony?
\015\012I have similar problem with a sony vgc-ls35e.
When I turn the computer on, only thing I see is white all over the screen, no text, no logos, no boot screen (bios), no windows starting, nothing at all. After few secs or mins, the computer still white.
I tried getting into bios, still white screen.
I tried f10 for recovery, still white screen
I tried botting from recovery cd, still white screen.
I opened the back of it, clean some dust (very little) check every single conector and everything looks just fine.
Any advise will be really apreciated.
