Motherboard dead. Please help!! Model #s?

Firstly..

On the back of my Sony laptop, the model says PCG-6L2L, but when I took it in to servicing to a SONY authorized dealer for a diagnosis, the paper it came back with said Model VGNSZ260P. What's up with that? Is this the same thing, just different numbers? My laptop is a Z series, but nowhere on my laptop does it say anything about Z series or VGN. Similarily, my friend just bought a brand new Z series laptop that was sold as a VGN (over $2500), yet again, on the back of his there is a PCG model number and nowhere does it say anything about VGN or Z series?!?!

Secondly, and more importantly.

The diagnosis came back negative. Everything works (cpu, ram, video, lcd, etc etc), but the actual system board, motherboard, is dead. When I boot up, it shows the SONY screen and I can get to BIOS, but as soon as it hits bios, or about 5 seconds after SONY symbol, everything freezes.

Naturally, the $800 they wanted is ridiculous. I am very tech savvy, especially with computers, I've been building them for a very long time, but have little experience with laptops. I am convinced that I can fix this if I can find a motherboard for it.

So, where do I look? Can I find a motherboard for this laptop? And which model number should I look for? Please, any help would be appreciated.

Also, I would consider selling it as is right now, as I said, it's all good except the system board itself, perhaps someone with techy know-how would want the parts or even to fix it, where would I go to get rid of it? Ebay? I don't want to take the chance then get a $20 bid and be forced to give it up for that, that is way too low, but of course I'm not expecting anything far more then that either.

Please, help in any way you can, I would greatly appreciate it.

Now that I have found this forum, I will participate more as I am a VAIO user and have always been. I may have to purchase another, but really, I'd rather fix this if it is doable.

Thank you in advance.


PS. Just in case the guy at SONY doesn't know what he's talking about, I just plugged it in again and started it up. I can get into BIOS, and when I get in, I can move around for about 10 seconds or so, and see everything, then it freezes. If I just leave it on the main BIOS screen, I can see the time going up second by second, after about 10 seconds it freezes. Could it be something other then MOBO?

 

If you want to try fixing, try if the motherboard is available here, though the parts seem to be quite expensive:
Sony Laptop Parts and Repair for Notebook Computers

For EBay, isn't it possible to set a minimum bid?

 

Hmm.. actually, that site is excellent, but how can I know it's the correct part?

Look at this:

A-1193-575-A - Sony Laptop Motherboards

It's only $75 and appears to be correct, but the SONY laptop this is for says vgnsz260pc, my code is vgnsz260p without the "C" at the end. I don't know if that means anything or what..

If this is the mobo, that would be awesome, $75 is worth it.

Like I said, on the back of my sony, it says PCG-6L2L, but in BIOS, and on my SONY receipt, it says VGN SZ260P (SZ Series laptop).. weird

 

Dunno, why not give them a call? I have the impression that the last character describes the color of the laptop, probably got confused with something else Is yours silver? I think the "C" means carbon fiber??
