shine a torch at the centre of the screen, it needs to be about an inch away and look for the picture of the file or logo or ?. If you can see it it will mean the bulb / backlite that lites up the screen has died.
ok try taking out the ram and battery and disconecct power adapter, Now press the power button keeping it pressed for 1 min then put it back together and turning it on again. If this does not work try turning off, then power back up holding F8 key and select repair my computer this put it into safe mode for problem solving. This will work for Windows 7, 8, 8.1, 10.

take the battery out and hold power button down or 5 mins. 5 mins may seem alot but try this as it sometime has been known to work unless you have a crack in the screen then you may need a new one if it is like the S3 screen.
Is the laptop turning on every time and displaying the picture then getting so far and then shutting down? If so the board may just need reflowing and you can do the job with a hot air gun on medium this is reflowing, for reflowing the you need to bring the componants up to about 230 to 250 degree's in order to reach reflow temp so that the solder holding the componants is resoldered and not cracked as this is more than likely the problem but firstly try this. You probably have blocked vents on heat sink and overtime the machine gets really hot and a solderjoint will fracture (the resulting issue), we have to locate the one that has done this and heat it back up to melt the solder again, i see this often and get them working again just be very carefull to not overheat the chip and motherboard and making it bubble but also don't be too shy. Over time the laptop sucks alot of dust and it builds up in the vents and stops the heat from escpaping. Dissesemble the laptop making sure to place the screws on a...

Paige is very correct about power speeding up the corrosion process so do not try turnning it on. I am sorry to say but do not do put the phone in bag of rice. It is like doing nothing the moisture will still be inside . You need to strip the phone and take the motherboard out. If it has metal plate's ie heat sheilds you will need to very carefully remove them so that you can gain full access to all the componants. Once the heat sheilds are off, clean the board with old tooth brush and isopropyl alcohol and then do it again. You may also need to put it in a ultra sonic cleaner if you have one or can borrow one. Once this is done try the phone again as I have had quite a few phones that i have had fire back up just by doing the above. The isopropyl alcohol will not only clean the board but it will push excess water out and away from the board. In extream cases you may need to gently reflow the corroded componants as the contaminant /particles in the water will corrode /crack the soldered joint. This is why...
I had an intermetent issue with my tv i tried allsort's but then found the AV board inside the tv had some componant's that had corrosion / corroded. After cleaning with isopropyl alcohol and a toothbrush I then resoldered the culprits with new solder. It has now been running for ages without an issue. You could also google the tv's model number , ie Phillips 32---------led tv dvd combo channel randomly changing issues or channel switches over by its self. If you do not find anything in relation to your problem try writing it another way but keeping the make and model number.
Hi I have had this problem also but i found what i beleive is the issue it is the u2 ic. It controls the charging. If you google/youtube it you might find it answers your question. (i hope) Ps i am no expert
