Hi all, recently my screen started to go "no input signal".. so i tried with all i could.. this is the list of the things i did..

1) use multimeter to test connection on av cable. all works well.
2) used my laptop and applied extended desktop. touchscreen was working but same "no input signal".
3) i then dismantled the lcd , disconnect and reconnect every cable again.
4) Voila! i can see the windows bootup screen for 3 secs.. then gone.
5) i shutdown my pc, off my lcd.. restart pc and power up lcd..then i get the "white screen of death".

i have been doing quite alot of search. maybe due to lcd ribbon, bad fuse?

thing is im not sure which is the fuse that i should check on. tmr i'll use the multimeter on the ribbon to make sure there's no broken connection. im attaching the pics and hope any guru can give some advice.

ANY help would be appreciated.

Thanks in advance!

Hey, I am having the same problem and its driving me crazy? Wondering if you found a Fix?

I had a problem with this creen and the ribbon cable.
Then i also had a problem where it would get a light on the button board come on but nothing else would.

In the end i had to get a replacement controller board.

In your case i would definatley try a ribbon first. Its a horrible situation to be in and i hope you get it sorted

Also make sure you do not power the screen when out of its case with controller board touching lcd......

I used a bit of card to slide between when testing it out of casing.
