Repalced LCD only white blank screen

[davebugyi]

I relplaced my notebook LCD Screen:
LQ164M1LA4A
with
LQ164D1LA4B
The reason that was the previous model was unavaialble or at insane price (300-400 Euros, but still out of stock).
BTW< when ordering, the guy said, that this should be working.

Now, the new screen only shows blank white screen when booting up. Any ideas/help?
Thank you!

Forgot to say: Notebook is Sony VAIO VGN-51FWZF/H

Well the #1 thing would be, how do you know you hooked it up right? Did you recheck the connections/cables?

Also the resolution of the 2 screens are not the same, the 4A is a 1920x1080, the 4B is a 1600x900, not the same screen at all. I would think in order to work properly, you need to get a 1920x1080 screen.

Try ebay http/shop.ebay.com/i.html?_nkw=LQ164M1LA4A&_sacat=0&_odkw=http%3A%2F%2Fwww.aliexpress.com%2Fwholesale%2Fwholesale-lq164m1la4a-.html&_osacat=0&_trksid=p3286.c0.m270.l1313
or http/www.aliexpress.com/wholesale/wholesale-lq164m1la4a-.html or

I thought so, but the tech guy said (where I ordered the screen), that it should be working.
Also I read from Vaio owners, that replacing the 1600*900 screen with 1920*1080 works.
Strange it is not working vice versa.

I'll try to check the connections again.

BTW, Getting a cable for this screen can help? I mean changingthw whole LCD Cable/Inverter parts.

New inverter could help, could have been the issue to begin with, unless it was something obvious like a cracked screen. Also keep in mind you could have damaged a connector when replacing the screen also. Aside from the whole screen may not work with that model thing.

The problem was getting the same screen - I contact at least 25 resellers worldwide, they did not have it. Tried e-bay and sites like that - they had the item online, but after contacting them they said, it's not avilable.

BTW, this screen is same manufacturer, all specs are the same except the resolution.
It has 2 ccfls, inverter board and even the connector.

you sure it was your screen that was faulty in the first place?

 

[davebugyi]

Cracked screen - 150% sure

 

[davebugyi]

Maybe getting a new LCD cable?

Have you checked for a full screen set including the bezel? People sell broken up laptop parts, including full top covers with the screen.

Could you fix this? I'm having the same problem. I changed the screen and the flex cable as well. Still getting a white screen.

Hi

I own a lappy repair company in the UK....

It has to be the EXACT same NEW (not secondhand) screen.... it MUST have identical numbers on the white sticker on the back of the screen....

All the best Brett
