No IF's AND's or BUTS about it. nd--do NOT try and "hit" one--it WILL fade again-usually in 2 months or LESS--and look WORSE than before!!

100% correct. Only thing I might add is that I have put hardwired brighteners in those, which buys a few months or a year. Also, if you turn the G2 SLIGHTLY down, I have found that it will fool the circuit and allow the picture to come on and stay on faster.
Keep an eye out for another set. That one isn't worth fooling with unless you can get another one to rob the CRT out of.
