Display problem during start-up

Hello everyone! I'll have you aware that my english is very average so please excuse me..
I'm not really used to go on forums to fix my problems but now I need some good advices, and sorry if I wrote too much but I need to give you all the infos i got so you can identify where the problem is.
without details,my laptop must've sustained a chock during a party with friends, and i don't knoz what kind of chock it was, all I know is when I woke up trying to use my laptop it started on a white background with the famous colored or pixelized lignes whatever you call them, I then really thought the display was ****ed up, but after a short while (5 mins) the white background and ligne were gone and i had the password label space you know ( i'll put some photos so you guys can understand what's happening ), it was really weird, but I could use my laptop now even thought there was some flashing coming from the sides of the display, even more weird after another 5 minutes, my compture has completely recoverd, i could fully use it with some minor problems like if I move the laptop or its display roughly some lignes appears on the display again..
the problem is that, all what I said happens everytime I shutdown my laptop for too long, for example if I restart my laptot everything will go fine, but if I want to sleep et shutdown it and start it tomorrow everything i said will happen again
I'm very thankful you read all this, and I really hope it's the band connecting the display to the motherboard but not the display, because this time it's a laptot that can go to 1920*1080 not 1360*xxx like i'm used to use, it will cost me an arm i think..
anyways I hope this will help to tell me where the problem comes from
and sorry again for this disgusting english

 

Likely damage to the LCD panel board.

You'll probably have to purchase a new 1080p screen. They are no that expensive, so no worries. Download HWinfo64 and find out what model your screen is.

 

okay i'll try it & search.. thank you for the quick answer really

 

Sorry for the double post.. but i'd like someone to explain to me why there's such a difference in price in display replacement on ebay.. like is there a display better than another ? i don't get it
https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=700-15ISK+15.6"+replace&_sacat=0

 

Please just download Hwinfo64 and tell us what model your screen is.

 

I've already installed but it does show that it's unknown.. anyways here's a screen

i have an IdeaPad 700-15isk ( lenovo )

 

The panel is a NV156FHM-N42. I would not recommen buying the same panel tho, it's absolutely bad. It has horrible color coverage etc.

@t456 Any idea what panel he can updrage to without making his eyes bleed?

 

The AUO B156HAN01.2 should be a good choice and they're not that expensive.

Be aware that most sellers will sell ' compatible', ' fit' or ' panel for', which means you might receive that panel, but you'll likely get something else. This listing seems like it's for the genuine article, but it is a bit costlier:
15.6"INCH B156HAN01 B156HAN01.2 laptop LED screen Grade A+ 1920*1080 30pins

You could ask one of the sellers of the cheaper listings and request specifically for this particular panel and tell them you'll shop elsewhere if they can't guarantee to ship an exact match.

 

Thank you guys, everyone one of you.. i appreciate <3 <3

 

Btw @t456 I know you've some decent knowledge but how can you be so sure that a B156HAN01.2 is compatible with my laptot.. are the number of pins (30), resolution,and the 15"6, the only criteria and are enough? sorry for bothering you

 

That, plus both have a 2-lane eDP interface, 0.50mm pitch socket, wled backlight, similar outside dimensions, mounting type and connector location.

Resolution isn't really important as such; it is the lane count, eDP version and refresh rate that limit the maximum supported resolution. Size only matters if you want to install the lcd in the display lid, but if that isn't necessary then anything from 11.x" to 17.3" would run perfectly alright.

 

Well thanks alot... you guys really were of great help

 

Guys.. I asked a friend of mine to buy me a B156HAN01.2.. he did show me the link before buying but after receiving it and bringing it to me... it was not a B156HAN01.2 but a B156HTN03.5.. i did some researches but idk, they're pretty much the same.. Could you guys tell me if i should tell him to go and refund or if it fits with my 700-15isk ?
@t456 what do you think bud ?
Sorry to bother

 

It is compatible, so it'll run fine. If the listing didn't mention ' compatible' or ' fit for' then you might want to send it back; it's even worse than your old panel. A black value of ~0.8 means you'll have at best a grey-ish background on an all-dark scene. If you're not bothered by something like that then all is well, of course.

Reviews of all panels, for reference:

• NV156FHM-N42 (old panel)

Spoiler: Good contrast due to its low black value, but a quite a poor gamut.

• B156HAN01.2 (my take, budget-friendly)

Spoiler: Also great contrast, plus a decent and accurate gamut.

• B156HTN03.4 (closest match to the 3.5)

Spoiler: Awfully low contrast and a poor gamut.

 

Indeed.. everything you said fits.. i feel like this panel is even worse than the NV as soon as I turned the computer after after placing the HTN I felt like the black color looks more gray than black but the overall price was 50$ idk if it's worth it but..it's fine for now.. it'll save me an enormous time trying to blocking the screen at whatever position for minutes to finally be able to use my computer.. I think i'll get used to it
thanks @t456 and everyone else you really were a big help
