Hello there.  I have a N64/ GBC double-sided light-up sign that I obtained a while back.  It has is made by TecArt Industries, INC. right out of Farmington Hills, MI (right around my location, so that's pretty cool).  I got it and the bulb was working; two years later it is no longer turning on.  It was been sitting safely in my basement, so no drops or anything occured.  I want to get it open to change out the light, yet I cannot get it open.  I was wondering if anyone could help me with any information behind it.  It has the 4 original screwed, in which I took out, yet that wasn't the answer to opening it.  There are two screws on each of the sides.  It almost feels like the side panels can come off, but I don't want to force anything.  Here are pictures of the sides and whatnot.  Thank you in advance!

Are there any screws under those black nubs?

Nope. Already tried to remove for that reason, but they won't come off.

I would assume the non-cord end would slide upward perhaps? Longshot, but have you tried calling the number just incase they're still in business?

EDIT-   They're still in business!

Try to contact them on their site with your pic and they can probably help.

Im wondering if the screws on the sides hold either the front or back faces of the sign in place. Have you tried removing both screws from both sides and pulling/sliding the front or back face panels? Looks like it would pull away from the unit more than it would slide.

Nice man.  Good looking out!  I'm going to call them tomorrow.

Any update??

I've been hella busy the past week; that's no excuse, but I'm a known procrastinator. I'll update again when I give the company a call in the next few days!
