I am trying to fix my outside temp LCD. I've read all the posts, but can't find an answer. So I thought my capacitor was bad. So I got it out and I have a 4 pin not the 5 pin. I only see two tantalum capacitors, can I replace those with aluminum ones? The backlight works and the screen is clear, no blackening or bleeding. The fuse is good. What else can I test?
