Hi from an electrics simpleton.
I have a wall mounted backlit display unit, that has 4 T8 fluorescent strips linked to a single internal ballast. The problem is that when I switch it on at the socket, two of the tubes flash once for a split second, and then nothing. If I switch it off and then back on again, nothing happens unless it is left off for some time.
This leads me to assume that it is the ballast unit that has failed, or should I try replacing all the tubes to see if that works?
I don't want to buy 4 tubes unnecessarily if it is a faulty ballast, and I was hoping that someone more familiar with flourescent fittings could diagnose the problem for me.....
Thanks for your help
