Yes sir, i adjusted the control on the flyback ,the first one the lower section adjustment,it maybe the focus.because when the pic is snowy i adjusted it and it works fine. i think the upper adjustment is for the screen ? if so,i`ll try to adjust it tommorow. i will give you feedback sir later on.
Thank you again for your help. |

sir, If it is a bad picture,how come that the TV is working w/o interruption in my viewing for a long period of time without changes in pic or sound .my real problem right now is the tv will not start up on its usual operation,after switched it on i heard a high pitched of sound , relay (1 click),lit is blinking more than 10 blinks then it will start sometimes it took 2-3 min unlike before 10-15 min.Anyway, if is a bad crt i have nothing to do until it is not usable anymore before throwing it to junkshop.
Thanks a lot guys  . |

As minnie says possibly a weak crt, for which you must have similar to try out and prove faulty. |
