I just need to know how to link up my Allegro DVD/VCR REMOTE CONTROL to my Phllips Magnavox Television.


TUNING This DVD+VCR is equipped with a frequency synthe- sized tuner capable of receiving up to 181 channels. These include VHF channels 2-13, UHF channels 14-69 and CATV channels 1-125. Auto Channel Programming 1. Choose the SOURCE SELECT option, then use b / B to select TUNER. Use b / B to switch among TUNER, LINE1, and LINE2. 2. Choose the AUTO CHANNEL SET option, then use b / B to find channels. • The tuner will automatically cycle through all available channels (TV/CATV) in the area and place them in the tuner's memory. •After the AUTO CHANNEL SET is complete, the TUNING menu will hide and return to the TV screen automatically. 3. Make sure the TUNING BAND is set appropriately (TV or CATV). • TV : If you are using a standard antenna to receive channels. •CATV : If you are using basic cable to receive channels.

Tuner will not pick up cable box on channel 3, front and rear AV


In order for the TV to work with the cable box by using a piece of coax and tuning the TV to channel 3, you must make sure the TV is in "Cable" mode on the tuner and not "AIR or Antenna" the frequency maps are different between these types of service and channel 3 cable will not be the same as channel 3 on Air or UHF/VHF.

Often there is an auto program feature on TV's that will "scan" for all available channels, and this should select the proper input type.

Hope this helps!

Making the TV VHF plus UHF cable ready


If your tv tuner on vhf only goes to channel 13 you will not recieve uhf channels if you are hooked to cable tv. You can do a search for mid band to uhf converters (converts uhf to vhf).We used to use them in the early 80's. Even if you can find one it will only go to channel 22.

Would you confer with me on this couple in Australia


If they are looking for analog ABC, it is low band VHF, ch2 to be exact,where the rest are high band VHF, and needs a decent multiband antenna to get it in alot of areas, well in Brisbane at least. We have Mount Coot-tha that has a good propagation to most metro areas approx 40km radius, although it starts to get a bit noisy on the ABC due to lowband interference issues. .
There are many areas of AU that use UHF for TV also. Not enough hills in many parts of the east coast to get the coverage, so there can often be UHF translators that you need to tune onto. I suspect the ABC problem does relate to them not using an antenna that is suited to VHF, saying this of course if they get the other channels (7,9, and 10) ok.

Go here for a more specific channel/frequency guide to determine if it is the problem by location. ABC is on different channels almost depending on what suburb you are in for some areas. If the DVR can do digital, then they should go that way as it is now UHF ch21. It may be that they are trying to get analog signals, that will be turned of in the near future... so tuning the system in for UHF propagated digital is the way to go.

Back in the day when I used to do antenna I recommended the Hills PF11 antenna, multiband 11 element yagi with low/high band VHF/UHF, or a PF17 (17 element) with mast head amp if they are in a marginalised signal area. But a UHF array is still the best way to go if they can process a digital signal. Hope that helps :)

VHF stations WILL NOT display. UHF stations WILL display. Have tried both the remote and the controls on the TV. What is the solution?


a no ufh channels would be a setting in the menu, but when your vhf channels go, the problem is typically the tuner itself, or the band switching ic. could be either. you will need a schematic to know what voltage is supposed to be on the pins.
