Customer said " sound no picture", 32" LED TV, OK, Its common LEDs problem, $50 to fix your TV, I got an APProved..
I tested with my poormans LED screen tester show as PIC1, LEDs screen has no problem.
pic2 shows someone has opened the LEDs screen before me, with the LED tester result I dont think I need to open the screen, TESTER shows all LEDs are good.
pic3 I jump the power-on and BL-on, the back-lite did not come on, has 12v and 5v, it is LED driver problem (shows 18.9v).
, with power PCB ebay for $31.95, I need to have at least $75 to do the job, maybe TV has man-made problems, new cheap LED TV cost $100, Lets see!!
PS: In my service area, lots of DIYs.
