DV6000, DV9000, TX1000, TX1, TX2 or TX2000?
If so these and machines that are similar to these designs have a flaw. While fixing the machine is done by swapping the mainboard the cost looks to be nearly the price of a laptop.
So yeah... pretty much exactly as I said.
The laptop in question has been frequently used with our HDTV in the past without much difficulty. Now, however, it went from only showing a garbled screen, to nothing showing on the screen of the TV, to the laptop losing both the desktop and the mouse pointer (and showing nothing but the desktop background) while the TV continued to show nothing, to the laptop blanking out as soon as the cable is plugged in and the TV still shows precisely bupkis.
Nothing but a hard reboot will bring the laptop back to life, and as far as I can tell, the television isn't even detecting an attempt to communicate with it. The laptop runs normally when no external monitor is connected, and the TV works fine otherwise also.
As far as I can tell, the only thing that has changed is that I attempted to use the laptop to test my desktop monitor when it started failing. I unplugged the laptop from the TV- it had been in use and working fine until I asked to borrow the laptop for a moment- and plugged it into the desktop monitor. The desktop monitor didn't register on the laptop, and once I had unplugged the cable (VGA cable, working fine as far as I can tell) and plugged it back into the TV, the problems started.
Any help at all would be greatly appreciated- the problem is... odd... enough that I'm not even sure how to phrase it for a Google search, and so have been finding lots and lots of irrelevant information.
