How to make sure that the screen is dead

[ahmed1186]

I put my phone to charge before sleeping yesterday, when i woke up, i unlocked the screen and phone was charged fully,
Suddenly after 3 or 4 seconds my screen went black! but i still can hear touch sounds, my computer recognizes the phone storage and i can feel the vibration when i turn it on or off.
I've also tried wiping and flashing a stock ftf through flashtool, nothing.

So my guess is the screen is completely dead and i will be replacing it shortly but before
is there any way to make sure that the problem is with the touch panel only? so it's not related to the motherboard or any other component?

To make sure that screen is dead use hammer or other heavy and hard object.

You need to place it on the screen with good amount of speed to get give this object more power.
I would recommend dropping it in the middle of the screen so you could be sure that screen is dead.

Im not recommending using car or dropping it from high, because there is a chance that you would kill not only screen but also other components of the phone.

That's not funny at all.

Well... when I saw this title I could not resist...

But to be on topic. If fresh flash dont help, there is no "software" way to check if screen is dead for sure.
XZ construction is tight as hell, and only way to fix screen is replace it in service center OR make it by yourself.

On aliexpress you can buy XZ screen for less than 25 euro

Its not much, and if you played a bit with phones before its gonna take you less than 30min.
I ordered screens from ali few times, for my old Xperia Arc S and Neo V. no problem still work like new.

But because you need to remove back panel, I would recommend buying it too, its less than 7 euro for panel with NFC antena
You get all tools with it, and only what you need it hair dryer or wet towel that you put in microwave. Its necessary to unglue back panel.

PS. I know that it sound weird, but one time when I have Galaxy S and screen was dead... I throw it ""by accident"" on the ground... and its start working xD Im not saying that you should throw it... but you know... ""shake that baby""

I was already considering the "shake that baby method", it might be just a problem with some inner connection or cable or something.
That's why i was asking if there's is a method to make sure that the screen is completely dead, so i might not need to replace the whole panel.
And about the replacements, i read some reviews on similar products on amazon, most are complaining that they started to see blurry text, lower brightness, microphone not working and alot of other problems, you seem exprerienced with the procedure of repairing so what do you think?

Well, in terms of changing screens I bought screens only for Xperia Arc S and Neo V If we talk about smartphones :]

I speed almost whole day looking for it on eBay and Aliexpress. Of course before that I checked professional shops and local services, but its F hilarious that they want even 150% of phone price JUST FOR SCREEN....
I always sort list by number of orders, so I have chance to read more comments, and most of this time I spend reading them. If I found even single comment that say that quality is bad... I checked next one. And after few hours I had 2-3 screens to choose.

And in terms of quality... its hard to tell, most of problems are made by person who put that screen in phone, not screen it self. And because as I said build quality of new phones are tight as hell, 0.5mm difference and something is not working.
But overall quality of those screens that I had where good. I didnt had problem with brightness, ghosting(in moving object) or blurry text. I only had problem with less saturated colors. Difference is not huge, but if you spend with phone some time you see that its about 10-15% less saturated.

To be honest with buying something online that is more complex than brick and it contain electronic components its always hit and miss...
I could had luck with screen, someone could not have... Normally I trust online shops, but its better to spend whole day in front of PC than buying first product from the list...

In terms of actual replacement, instead of inventing wheel again, just check YT videos, watch few of them, and if they have link in description for screen, check them, sometimes they give link to screen that doesnt cost fortune and you know that you can get good quality product.
here are few of them:

Just remember to prepare everything, flat place for work, all tools, and few cups or bowls for parts... flat table or not, Its better to keep all screws in bowl :]

This look a bit average looking at comments, most of problems are with dead pixels.

Weird that for XZ screens there are less offers that I would though :/

I found this one that look promising:
http://www.aliexpress.com/item/For-...6601-LCD-display-touch-screen/1902384532.html
and if you want whole front panel
http://www.aliexpress.com/item/For-...e-Assembly-Black-Replacement/32279043240.html

But as I said its hard to tell if you get screen without problems... I would say to check eBay or Amazon, but to be honest its all from the same place so what the difference?
