To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Hello,
Most cases the hinge is a part of the LCD screen and bolts to the laptop case. You may need to replace the whole LCD. You best bet would be to give HP a call or look on ebay under your model for parts.

The blob is a phisically damaged part of the LCD screen. Unfixable, the screen must be replaced and it will be expensive.

Hi yes - any damage to the DS screen cable will be picked up by POST ( powe on self test) see www.dsdoctor.co.uk for parts or repair

this is a very common problem if you always hav your llaptop on then its basically fried into your screen. if not and u damaged it somehow then you need a replacement. and if none of thats the case your monitor got 2 overheated or maybe one of your lcd cords coming from the mother board(hard drive) of your laptop is loose or damaged by heat

As the graphics controller/card is either integrated into the Motherboard or stacked on it, the case has to come apart to replace the screen. You can check online auctions or other outlets for replacement screens or non functioning laptops like yours for the parts you need. You didn't mention whether the screen housing was damaged or any other damage to the case, if there is the laptop with a bad mobo or hd for parts would be the cheaper option. But you must also be able to or have someone who can preform the labor for you as it's not for first timers, otherwise I would look to replace the laptop and part yours out. JMHO

data cable casing for ur laptop is gone it needs to replaced

Hello Ayoitzpyda, The problem you have is related to the connector from the mainboard to the lcd pannel. It got loose from it's socket and can't send the video signals to the lcd pannel to display. Or it is probably damaged. However in both cases you will need to have it checked at a service center. This shouldn't be an expensive repair but I recomand you to ask them a cost estimate before they actually repair it. If you have a damaged connector that needs to be replaced, it will be easy for them to change it, but if they don't have such spare parts it will be very expensive to get a new one as they are skipped only with the entire screen as a whole part. If you need more informations please post back.
