/diy/ - Do It Yourself

replacing the backlight on a TV is super duper easy after you've done it for the 20-th time. the first 10 times, you'll damage the screen beyond repair, and the next 10 times will result in various levels of breakage. but on your 20-th attempt, SUCCESS!

problem is, the backlight itself is the problem only 50% of the time, the other likely culprit is the high-voltage circuit (about 1000V) that powers the lamps. to determine which is which, i use a 1000V circuit i pulled out of an old scanner to test the lamps.
