Dell 24" Monitor
MV230HM-N30 B4
S2318HN/S2318NX
Cat knocked over and broke LCD screen, am trying to convert to LED light utilizing existing LED edge back light strip (4 groups of 16 LED lights=64 total) These are numbers on LED strip, E466169XY-MC 94V-0 and 1602 N52PBY5 C52NA23. Only one PCB that's got power section and video section see attached pdf's.
After tear down reattached connectors and turned on: Power light came on, LCD flickered several times, first 16 LEDs came on for 3 to 5 seconds and then both shut down, power light remained on. After that nothing came on except power light (LED)
The following DC voltages were taken with everything connected to PCB and powered with 12V adapter that came with monitor
Checked individual LED's with 3volt power source and all seemed to burn (really bright), so think they are okay. Don't know how to start trying to jumper contacts out to get LED's to come on. There are no descriptions/legends on any of the components and have been unable to locate any diagrams for monitor or PCB. Know I can just junk it all and go buy string of LEDS and install, but would rather burn this one up trying to get it to work before buying something else. Any suggestions on how to proceed would be appreciated
