Repairing the Vizio 42" TV...

This isn't ham radio, but it is electronics related. The Vizio LED TV in the living room started having trouble with a dark band at the top of the screen, and progressed until it was difficult to watch. It looked as if the back lights were failing. I sourced the parts online for $29, and broke into the TV tonight after dinner. Took about 2 hours to repair and reinstall, much cheaper than a new TV!

 The dark band has almost moved all the way down the screen, making it difficult to watch.

 TV laying face down on a blanket toss on the bed to protect it while working...

 Rear cover removed, exposing the two boards and a zillion screws around the perimeter...

Back, face trim, and the LED screen removed and propped up against the wall...

 White backlight diffuser exposed, after the face trim and LED screen removed...

 Backlight frame exposed, with the old back lights removed. Note the wiring harness on the RH side...

 New back lights, ready for installation...

 New back lights installed. I powered the TV up to check them out... The bottom strip of the old back lights is all that was working when I checked them!

 Everything going back together...

 About to reinstall the back...

 Old back lights and harness heading to the waste bin!

 Only took about 2 hours, and it's all back in operation. I got the lights from www.ShopJimmy.com
