Re: Toshiba Satellite LED screen no backlight
I will make some drawing of the wiring tonight. thats the only way I can see it straight.. BTW, what would cause the OLD ccfl backlight not lighting up after testing with this new LED? that actually bothers me a lot, like something burn in mobo? or some gpu related?

Re: Toshiba Satellite LED screen no backlight
you mean that I have wrong pin (from motherboard) connect to the led (ribbon)? It does says "Toshiba" on one of the socket so put it there obviously. on second thought I think I did mistakenly put it on HP621 socket once but no backlight either.

I'm waiting fro my brother who's into electronics to come, for the meantime I'll try to crunch some of the info above and going to find multimeter and learn how to use them
I'll be back.
already spend 100 buck for the LED screen and I'm not going to let this thing die on me!

Re: Toshiba Satellite LED screen no backlight
the schematic found here: [url]https://www.badcaps.net/forum/attachment.php?attachmentid=67307&d=1373766252[/url]
are quite similar, its LA-4982P while my board is LA-4981P. perhaps just minor change?
can I use this as reference? I'm very new in this. dont even understand what exactly I'm looking for.
I found many VIN in these pdf schematic but can't decide if they're connected to LVDS.Re: Toshiba Satellite LED screen no ...73766252[/url]

Toshiba Satellite LED screen no backlight
Hi guys
I have a problem with Toshiba Satellite L500 led / lcd no backlight problem
the chronology is like this:
1. Toshiba Satellite L500, busted LCD, Still have backlight. Only parts of it cracked.
2. Order LCD screen from online, part no: LP156WH1
3. problem with stock lead to replacement with compatible LED screen part no: LP156WH4
4. assembled the LED screen (no inverter obviously) > boot, blank no backlight. image is visible but very faint
5. tested with old LCD + original inverter...
