HI there,

Here's the easiest way for you to troubleshoot this hardware problem.

1. Using an external monitor (whether your own or at a friend's place) which you connect to the laptop, see if the same problem shows on the bigger monitor. On most Toshiba, you'll need to transfer the video signal by holding down the "fn" key and pressing the F5 key oncew you've attached the laptop with the video cable.

a. If the same negative-like appearance appears on the larger montior, it means your problem is with the video chip which is soldered to the motherboard, the plug where the laptop screen attaches to that board, or damaged circuitry in between. This would almost surely cost more to repair than to buy a working used A105.

b. If the external monitor shows up clear and normal, then you have narrowed the problem down to the the laptop screen's connecting cable plug and there's a chance that the cable's end that plugs in has electrically shorted out elements, or the surge from the water shorting some curcuits damaged what's called the "screen inverter" or the LCD screen panel or both.

2. If the result is b., then you should look into what a local laptop repair specialist would charge to double check this and do the replacements. Then, you'd be able to make a decision that fits your personal needs and situation.

Best Regards

Difficult to comment but if a laptop comes in for me to repair and the hinge is broken and maybe cabinet damage, I would offer to replace the broken parts and replace the DC jack, if it was faulty. It is part of the service but may not be cheap to repair!
Hinges usually become loose and very rarely break.
Did the laptop work on the power supply but not on battery?

very sorry to tell you that the lcd has gone bad because your laptop shows exact symptoms of this case.
As per what some HP costumers have told me HP takes this as a physical damage and does not give them a warranty even if it is in the warranty cover
Finally you will need to get it replaced

This is the most expensive fix after a motherboard and may cost you $180 or 8000-9000 INR

My screen looks like a photo negative..I have a Toshiba Satellite.


Right click on your Desktop, click on Properties, then go to the Settings tab and set the color to 32 bit True Color.

It sounds to me like your display settings are set to monochrome/black and white.

Best Regards,

When you are on the print window at the end of the process, look for a "Preferences" or "Options", then look for tabs or other menus that say "Color" or some sort of "output" mode and see if there is a negative option you can disable.

HP Pavilion DV7 Display problem


How long have the colors on your display been "reversed/inverted" and looking like a negative....... Did you drop or damage the laptop in any way (sudden shock/bump)? Also, has it been allowed to overheat (if you run the laptop while it is sitting on a soft surface such as a bed, pillow, couch, etc it can allow the motherboard to overheat because it cannot get the airflow through the cooling system through the fan/vents because they are blocked). Have you checked to see if your laptop is included in the "HP Service Enhancement" program???
