hello - if moving the plate the TV can work - you still have false friend contact - or printed cut - it is not something else in my opinion - guide yourself by the tensions in the horizontal driver transformer - often this one also desolves - controls that get the pulse to the base of the transistor- by giving PW-
many times you cut the printed just in the circumference of the fly- control with good light and magnifying glass the plate that is not broken- insist on that and with patience- since you feel that noise turns off the light and in that way tries to find the fault - when moving the plate-

hello- there is nothing of oscillation motive that does not measure anything those pins- now it measures in the pin 24 of the jungle- this one feeds of the source- through R 405 YR 410- if you do not have tension there it is not going to work the jungle - In case of doubt also measure that pin with mass must not have continuity - if the jungle is broken - it controls well the printed one that does not cut or the OPEN R- from the exit of the source of + b to the jungle-

place the tester to ground and positive to L 804- if you have tension at its output, place the tip in R 805 before and after it, the same for R 810- and comment- if there is no tension, it desolves pin 24 of the jungle and measures if 9v appears on the form or more-

Did you measure as I told you in the form or after the R 810- do not measure in the pin- use mass tuner- or naked mesh of the tube- you did not tell me if you measure continuity the pin 24 and mass-
