Replace Ceramic disc capac
onedumbquestion:
Thanks What if the proper range is set to measure voltage on a dmm then what harm could be done? Would that be a way to discharge a 35V capacitor?
james_s:
Why would you want to discharge it? A ceramic cap rated at only 35V is going to hold a negligible charge. Discharging only matters when the voltage is high enough to hurt you. Just reinstall the capacitor and then find someone knowledgeable to help you with this repair because you are in over your head. Without help you'll just end up destroying the unit.
onedumbquestion:
I should discharge a capacitor by connecting one lead to the other without any resistance? That can damage the capacitor can't it? I thought if I used a multimeter to test voltage that would cause the capacitor to discharge
james_s:
It could possibly damage a large capacitor but we're talking a dinky little ceramic cap, you don't even need to discharge it, there won't be any charge on it and the amount of energy it is capable of storing is absolutely tiny. Just reinstall it and think nothing more of it.
onedumbquestion:
OK I put it back in Turns out it works, the only thing wrong with it is the backlight bulb is out I don't know the replacement procedure but I see people saying they had to splice on a new bulb It's seemingly from another discussion 14v 80ma 4.12mm width so I'm searching for it
