Hello to all. This GE TV 27GT613-CTC177 BH2 has a fast vertical roll. I thought this to be a piece of cake,but by now it gives me a hard time I have checked the voltages on the vert IC U4501 and they are all within specs. Only the frequencies are 45 hz on pin one and pin 3 instead of 59 hz. And on pin 5 the vert out I get a horizontal frequency of 15734 Hz I have checked C4505-C4506 they are OK I am running out of idea's and am wondering if someone has a clue to this problem. thank you in advance John H Smit Smit's TV Service Box10 Gunnison Utah 84634 800-355-4948 Phone&Fax 435-528-7955 Phone&Fax jsm@xxxxxxxxxx ----------------------------------------------------------------------------- This Email List is Public.
