Question about RCA F27242GY 27" TV
The RCA F27242GY uses the CTC185 series chassis. If it blows the main fuse the instant the power plug is inserted in the wall, then you most likely have a shorted power supply IC. This is a large almost-rectangular black IC mounted on the metal heat sink with STK730-020 (or -010) printed on it. Some sets have a metal clip over the top pressing it into the heat sink and some have 2 screws holding it in place. If you change it yourself then you must unsolder and remove the old IC, clean the surface of the heatsink, get a new STK730-020, apply heat sink compound the the back of the new IC, bolt it in place and solder its pins. Replace the fuse again and if you did everything right, the set should play fine.
