Question about RCA TruFlat 27F520T 27" TV
It is reparable problem. You see a blue line across the middle of the screen I thinks and posts this solution. The fault is due to the absence of vertical scan. In your set, there is an IC used for this purpose, and it has been dead short now. That is why you see the line at the begining, and it disappears a few minutes after. The vertcial output IC can be located at the main printed circuit board, usually screwed on to a metal heatsink to sink away the heat genereted in it while working. You can easly located it by the following method.
Look at the deflection coil, the coil fitted at the neck of the picture tube. From which, four wire will go towards the printed circuit board, and will be pluged on to it with socket. Just draw out the printed circuit board from the TV and turn it upside down. Look for the connections that I have menttioned earlier, four of them, out of which two of them will be for horizontal scan, and two of them will meant for vertical scan. Follow the vertical scan track, can be identified by two wires emerges form the board, will be connected via copper track and will go to the vertical section, from which you can identify the vertical IC fitted neareby it, usually will have 7 or 9 pin vertical type one.
There is no need to check it now, because, it has already been shorted and damaged in your TVs present case. Desolder it out from the board, and go for a new one of same type and number, replace it as the previous IC was, will solver your proble.
You must have a desoldering pump, a soldering Iron, solder wire, some knoledge in electronics,and more comecentration and patience. OK.
