As minnie says possibly a weak crt, for which you must have similar to try out and prove faulty. |
ok sir thanks a lot for the reply, i will check it again & post my feedback this coming weekend. |

| Bad picture tube. |
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  . |
