Question about RCA F27628 27" TV
Hi, I have an RCA TV model F27648 (color) that now only shows picture in Black and White. The funny thing is that all menus and Guide Plus menus are in color. Picture is the same on all inputs (cable, video1 and video 2) Any solutions? I tryed all settings and tryed to plug cable directly to TV instead of going through the components. No luck. Please help.
The route through the circuits in the TV from the various sources all lead to the final video amplifiers for red green and blue. Somewhere along the route is a circuit called a colour switch. This allows colour if the signal is strong enough, otherwise it only allows black and white. This fault suggests a weak video chip which is the one just before the switch circuit. the fault could also be a faulty coupling capacitor to or from this chip, or a low power supply voltage. Check for dry soldered joints around this circiut. Please note if resoldering on new televisions that they may have non leaded solder which requires about 50 degrees centigrade hotter iron.
