Hello, Im hoping to get some answers on this screen replacement Im doing for a customer. Ive replaced many screens but this one has me stumped. The Laptop is a Sony viao sve11 - 11.2 inch screen. Now I pulled the old screen and started to connect the video cable to the new screen. For some reason it would not connect and I no I was connecting to the correct side/location on the screen. I then hooked the other old screen in and the connection went right in. Pulled the old and installed the new again, still wouldn't go in the connector on the screen. I finally got it to connect but when I powered on the laptop there was no power to the screen, no back light, no faint image, so I believe this is a cable issue, I may have damaged the cable when I was connecting it since it took a while for it to finally connect up. Ok now what I have done to narrow the issues, I have connected the Sony to an external monitor with no issues, computer boots to windows fine. I have drained the power, removing battery holding pwr button for 60 seconds (did this several times) STILL NO VIDEO. I reseated the ram modal, still no video. I replaced the ram with a new stick, No Video. I connected the old screen back up which it did work but was cracked, now that screen has no power and is black. Im thinking I may need to disconnect the lcd cable from the motherboard and reseat it ?? but at this point I don't know. Need to get this machine back to my customer tomorrow, any help with this would be appreciated.. Thank you!

"For some reason it would not connect"
1) The replacement screen was defective @ connection
2) The replacement screen is a newer (slightly) different version @ connection (Sony engineers)
3) "I may have damaged the cable when I was connecting" More than likely.
4) Explain to the customer sony shipped the wrong/damaged replacement part.

Hey thanks for your help, Im leaning toward damaged lcd cable so I guess I'll start with that and see what happens. Will post back with results
 


Which is strange cause i held both old screen and the new one side by side with a magnified glass and the screens were identical as well as the connectors ??
 
Old one fits on/off no problem. New one has to be forced and doesn't function. If nothing is different at all, then how can this be? I do not doubt they appear identical but something is amiss. Strange maybe, unreliable replacement screen it's your call.
