Discolored Display Equals Loose LCD Cable


A customer brought a HP G62 laptop with a video issue. It was displaying a light blue tone on every background where it should have been white. Also the pixels were randomly turning  on and off.

The funky discoloring initially looked like it could have been a virus. Knowing about the problems that plague the DV6000 and DV9000 HP laptops, it was possibly a video issue.

I disassembled it down to the board and discovered there wasn't a visible GPU. The processor has two dies on the chip to possibly indicated integrated graphics.

Perplexed I put it all back together and discovered the problem has fixed itself. The cable coming from the LCD screen was apparently loose from the board and was causing the glitch.

For every successful business operating in Boston, network support invariably becomes an issue at some point. Being hooked up to the World Wide Web, or Internet, is one thing; however, chances are that when it comes to the day-to-day operations of the company, the Intranet is just as important.

I have a laptop that is in dire need of repair. The problem is that the place that the manufacturer (Toshiba) recommends has a policy of erasing the hard drive if it is damaged or "the software is corrupted". The laptop's hard drive is perfectly fine, but it has only Linux installed on it, and I expect that Linux will be regarded as "corrupted" software, resulting in an unnecessary erasing of the disk.
