Improving the brightness of old Tvs

Hey guys,

sorry it took me soo loing to reply... ive had internet problems. I am infinitly indebted to you for that ridiculously good reply. I am performing the procedure this friday. Wish me luck. I will reply and let you know how it turned out. Thanks agian. That reply was so crazy. Thanks. I feel very welcome to your forums. also are insulated/ plastic screw drivers 100 percent necessary? Will i have to use them to adjust the various settings? Or can i take it apart with the power unplugged and then toggle the knobs with my fingers after turning the power back on? Thanks
