POST error : video card malf : where to fix?

I have a 4 year old HP dv6500t CTO
It has a Core 2 Duo T7300 and Nvidia 8400GS.

The computer has run pretty much flawlessly the entire time I owned it.
I got an external monitor and was running dual display recently, when the next time I tried to restart, I get POST error: one long, two short beeps. Video card malfunction. I have read elsewhere that this was a problem with this mobo.
I imagine that the GPU desoldered itself ?

What can I do to fix this? i.e. anyone know of anyone that does this type of work?

I have found people selling replacement mobos online. do these ome with cpu, gpu, etc? or not?

If the above doesn't work, simply get a new system (it will just happen again - there is no permanent fix).

 

There are few repair shops that do BGA repair these days.

Does it not POST at all? Did you try reseatting RAM and using known good RAM?

Refurbished boards can sometimes boards affected but baked back to life. In all honesty I don't think it is worth repairing unless you find a shop that uses leaded solder. The chip is what is defective.
