P purewar Member Mar 8, 2014 #1 So im trying to power up my 3.5" lcd and when i put 8v from my battery to it, it just turns on for like half a second then goes dead. It does that everytime i reattach the wire. Am i undervolting it or something?

Bush sweet justice hi Mar 11, 2014 #2 Check the ribbon cable. I had a similar problem once. If that's not it, try feeding it something like 7v. You might be giving it too much.
