If you own a 48-inch RCA TV and are having picture and sound problems, you may want to try a few things before resorting to placing it in a shop or discarding it for a newer model. Several years of continues activity can take their toll on a late model RCA TV. But you may be able to fix the issues by performing various troubleshooting tasks that may save you money and get your TV back in working order.
Instructions
1. Make sure the power cord is not broken on your 48-inch TV. You need to make sure the power cord is functioning and not disconnected from the power source. Examine all the possible power-related issues that could lead to a malfunction.
2. Check the RCA TV's video inputs. Make sure that you correctly have it locked into the right ones. Audio and video devices on the RCA TV must be manually adjusted, and if forgotten and not switched back over to the normal input preset, you will not be able to get cable/satellite programming. This could cause the picture not to come up and the sound not to be audible. Check the "Input" button on the remote or the TV set itself, dial the inputs, and make sure they are set correctly.
3. Inspect your RCA cable connections on your RCA 48-inch television set, if you are still without picture or sound. The cables on a 48-inch RCA TV has one yellow, one white and one red connection prong on each cable end. There are six RCA connector prongs in total. You will find that there are yellow, white and red slots at the back of your cable/satellite receiver box. Make sure you have right prongs within the right socket connections.
4. Examine your RCA TV screen for a potential magnetization issue. You will immediately come to realize if you have a magnetization problem by identifying whether oddly random-colored blotches appear on the RCA display screen. If there is evidence of scrambled lines present, you will have to demagnetize your RCA TV set. Utilize a magnetic device of any size or shape; wave it slowly in front of the display screen, until the splotches disappear from view.
5. Watch the display screen to ensure that there is no "white noise" or other disruption which affects the quality of TV screen. If this happens, make sure you re-examine the cable connections on the back of the television set. You may have to examine the coaxial cable, which are hooked up to the "Ant In" port. By pushing down onto the coaxial cable or removing and then re-inserting the cable, you can tighten it within the television port, eliminating any unwanted noise.
