  • Trouble Shooting on Analog TV System

    17-04-21 Trouble Shooting Any system can be make or break the entire installation. I have been dealing with the complaint on modulators but most of the time the problem comes from the other part of system. And this is why I going to tell you in the following words. Golden Rule : Always check the connections before you blame the equipments. 1. Herringbone in TV Disconnect modulator from local channels and check modulated channel. If there is programming move the modulated channel. If the picture is snowy, use a low pass filter to block noise or data coming in from cable. 2. Horizontal Bars Rolling Through TV Picture 2.1. Check for a component of the system that is introducing DC power into the system. Disconnect that component and check TV. If the hum bars stop, use a DC blocker down stream from that component to block the power from getting to the TVs 2.2 If the rolling is only on the modulated channels, check for impedance mismatch by adjusting the video level adjustment pot. 3. Vertical Bars Rolling Through TV Picture Check for AC power getting on the line. Use a ground breaker in line. 4. Black and White Lines on one Local Channel Move modulated channel up to a new channel. If problem persists and all of the inputs of a multiple input modulator are not being used, check default channels on modulator to see if default channel is set to the same channel that the problem channel is. 5. Ghost on the Picture 5.1 Check for low quality combiner/spitter in system. Replace with high isolation combiner/splitter. 5.2 Check the type of coax used in system. Inadequate shielding in coax will cause ghosting. 6. Snowy Picture 6.1 Verify the modulator is set up for the proper TV channel band. 6.2 Verify the TV is set up on the proper TV channel band. 6.3 Read More
