Troubleshooting Video on the E2200IR

If your modulated signal looks ‘snowy’ or if you don’t see it at all, follow these steps to correct the problem.

1. If you are combining the modulator with the an antenna or CATV signal (as shown on pages 4 & 5) disconnect the antenna or CATV signal so that the modulator is the only signal in the system.

a. If this solves the problem, you will either have to change the channel you are modulating on to a truly empty channel or you will have to filter out the signals that are interfering with the modulator.

b. If disconnecting the antenna or cable feed does not solve the problem, continue to step 2.

2. Connect the RF output of the modulator directly to the RF input of a TV (make sure the signal is not feeding through any unnecessary devices such as VCRs or cable boxes).

a. If this solves the problem, there is something wrong with your distribution system. Reconnect your distribution system one component at a time until you identify which piece is causing the problem.

b. If connecting directly to a single TV did not solve the problem, continue to step 3.

3. With the modulator still connected directly to the TV, make sure the TV tuner is set to the same mode as the modulator. TVs have can either be setup to receive antenna signals or CATV signals. If the TV is setup to receive antenna signals and the modulator is set for CATV signals, you will not see the modulated signal on the desired channel. You may need to perform an auto-program search with the TV. This is typically an option in the TV’s setup menu. Before the channel search begins, the TV will usually prompt you to choose the type of input signal: either CATV or Antenna/Off-air.

a. If auto-programming finds the modulated channel, then reconnect the system. If you have further problems repeat steps 1 & 2.

b. If auto-programming does not find the channel or if it finds the channel and there is only an empty black screen, continue to step 4.

4. An empty black screen is usually an indication that there is no signal getting into the modulator. Verify that an active composite video signal is connected to the yellow RCA input jack on the modulator. An easy way to verify the composite video signal is to connect it directly to the yellow RCA input of a TV set.

a. If you do not have an active video signal, try another source. When you have verified that the composite video signal is active, reconnect it to the modulator and repeat step 3.

b. If there was no problem with composite video signal when you connected it directly to the TV, then call tech support for further assistance. Bottom of Form
