Hi guys, this set RCA F25422 CTC203AC4, has a farely good pic and sound, but has this fault that i never saw before,When i go to menu it usualy has a blue square with a yellow line,but this one instead of the blue has just green barely can see the menu controls,and also the channel # has a small green square like the menu,it all started with almost full red kinda like when you have a crt board fault and clear up, i suspect caps, since i had this chassis as a spare not used it for long time.any ideas where should start to look for this trouble.Thanks in advance.
