    Post electrical tape residue conductive??

    i know this is a weird question...but it relates to my 20x2 hd44780 char lcd. back when i first wired the thing up...i put electrical tape all over the thing...now i realize that this was probably not the best idea...here is my question: could the sticky residue from the tape left on the lcd be conductive? it is in direct contact with a few of the leads that get +5v and is all over the place. i keep having problems with the hd44780 chip on the back getting REALLY hot, like hot enough to give you a nice burn. i know it's not a wiring error because i've wired this thing like 3 times and it keeps overheating. anyone have advice?? thanks

    If you used electricians tape then it shouldn't be a problem... even the goo. Eletrical tape is designed to be non-conductive.. that's why its for eletrical stuff.

    I had the same problem with my mobo in my plexi case. I put electrical tape over the screws that held my case together so it wouldn't short the motherboard because it touched some of the soldering leads underneath the motherboard. Upon using the tape i noticed the sticky residue and thought nothing of it until I tried to boot the board. It would boot but wouldn't come up. So I took it out of the plexicase and it came up instantly; the first thing I did was replace the electrical tape with brand new (residue free electrical tape) and it worked on first boot. I have not had any problems since then.
