Question about Mitsubishi VS-50707 50" Rear Projection Television

1 Answer

No signal through Ant-A and/or AntB

I can not get a signal when the coax is plugged into Ant-A and/or Ant-B, its just static. I can veiw cable when I run it through the vcr and change the input to input-1. The same time the Antennas quick working, the remote to the tv did as well. The remote still works on all other components.

Home stereo with outside antenna, when I insert the coax cable into the stereo the radio plays fine until the type f connector touches the radio and that is when the static starts, please help

Hello, Try terminating the other end of the coax cable with a 50 ohm resister. Also .this could happen due to overloading the input with strong signals. If you know some electronics, you could connect two back to back connected diodes(in 4148) at the radio input end to limit the signal level.

I set my box up and got a lnb error so I changed the coax 2 times and tried 2 diffrent audio video cables but nothing seems to fix the problem I'm using an old ant the plugs in the wall is that why

I suggest you invest a small amount of money in a signal strength meter, usually used for aligning antennas and dishes but can be used for diagnosing faults. If nothing is coming out of the lnb or not managing to find it's way down the coax the box will have nothing to work with.
If there is adequate signal arriving at the box it would indicate a faulty box or bad software.

Can't pick up ant ditgital signals,why not

First what make/model of TV do you have? Does it have a digital tuner? (Manufactures had to add digital tuners at various times depending on the TV size)

Next what type of antenna or cable (basic, digital) do you have and how is it connected to the TV? Is it an indoor or outdoor antenna and is it pointed at your area stations? See or for details on where your local OTA stations are. (Note: antennaweb assumes an outdoor antenna but is very conservative in their list.) Antennas can be turned by the wind.

Do you have an amplifier or a splitter in the system?

First, remove the amplifier or splitter and try a direct connection to the TV. (I've had amplified splitters turn into signal filters after they failed. Then they gave no signal out from certain bands. Many areas only have UHF digital stations.)

Next check your cables for damage and try replacing cables. (I recently had a cable in the wall get damaged and had to rewire that outlet. The TV got good signal if I ran a direct line across the floor to another coax jack.) Alternatively, try connecting the TV to a different coax jack.

The final thing to check is the TV's inputs. They can fail. (I lost a few analog TV tuners to a lightning surge.)

I hope this helps.

How to connect an dvd to old tv

they make a small box called an RF modulator. It takes the audio/video signals and turns them into a signal the coax can read. You can pick one up at electronic stores. There usually about 15-25 $.

Crackling noise / loud static when tv is attached to antenna

Pick one:
RFI (Radio Frequency Interference) from nearby electrical/ electronic device.
Antenna misaligned to transmitter.
Antenna coax impedance mismatch.
Faulty connections.
Faulty antenna.
TV tuning.
If the OLD TV worked OK on same antenna it sounds like TV tuning or ANT socket/wiring loose.
Auto-tune TV with ant plugged in.
Get TVF (TV fundi) or friend to help align antenna.
Maybe a large bird sat on it.
Check coax for sunburn / deterioration. Renew if XX.

I have a Motorola Quasar TV and an outside UHF Antennae. I have coax coming from Ant. There are 3 coax connectors on the back and one pair of screw terminals for 300 ohm flat lead in cable that is...

You are losing a VERY small amount of signal using the transformer. It won't even be noticeable I'm sure if you switch to the coax in but the fewer connections you go through the less the chance of a bad connection. Use regular " Ant. In " coax connection or " RF in" whichever the wording is on the back of your set. Good Luck!

No Signal

I connected the cable to Ant-A, then connected a short cable from the out loop to Ant-B. Works fine. Didn't have a manual, had no idea.

Hello,65613 mits

Good Day, boofis68;
Sound like you may have voltage concern,9 volt source. Check for 9-volts DC to the Terminal PCB at connector JA pins 57 and 58 if missing, check IC9C25 (9-volt regulator) part # 270P677030 on the Signal PCB and replace the two caps. Good Luck, big IRISH.

My ilo has the built in atsc tuner

Try plugging in a powered antenna.  
The DTV coax input is for over-the-air HDTV transmissions which vary depending on your location and surrounding buildings.  I have the LCT32HA36 hooked up to a powered antenna and it works fine, but it wouldn't work when I plugged in the cable from the wall.
