Question about LG Flatron F700B 17" CRT Monitor
For some reason, when the monitor is turn on after 6 hours of rest or more, the monitor screen will turn yellowish just after a few minutes it is turned on. It looks like there are only yellow and red colour, without blue colour. It will keep yellowish in a while. If it is keep turning on for half and hour or more, it will become normal again. However, this will not happen after the monitor is working a long hours. Is this something wrong with the components inside?
Your problem is in blue color cathode circuit. as you say that it becomes ok tha5t means 1 cable wire is loose from computer to monitor. 2 crt base loose. 3 loose contact in blue video ckt. 4 signal processor cable to crt board connector loose.(blue wire)
