I picked this up from the recycle center. I figured out it had a bad ccfl by hooking up another back light I had sitting around(my old monitor).
Obviously replacing the CCFl isn't a very economic choice plus I figured my chances of getting a new one in w/o breaking it were also slim lol!
I bought one of these Chinese LED retrofit LED kits(pic attached):

After waiting the obligatory 30+ days for China Post shipment, I finally installed it. I removed the inverter transformer, mosfet and controller IC plus some capacitors to clear space for the LEDdriverboard.
It's working,but... I have a few questions:
1) It's edge lit. I assumed that I should install the new strips into the plastic refflector that the ccfls were in. Of course after the fact I saw a few videos where they eliminated the reflector... Should I have done that?? It seems bright enough I suppose.
2) DIMMING! The LED driver has a DIM lead but from what I read, there was only a "chance" that it would work. I just left DIM off. My PSU board has TWO DIM connectors. DIM-A and DIM-B.
The display just doesn't seem right to me and I wonder if the brightness is the cause.
Any ideas how to get it working? Preferably tied into the system logic,but even if had to install a pot and set it manually that would be okay. There is a hair stuck in the bottom of the screen so I guess I need to disassemble anyway lol! (where's my clean room lmao)
I plan to have it side-by-side with my new 24" but until then I can't compare the displays together. However I am sure that it can be better quality.
Thanks!
