Yupiteru MVT 7000 can scan but no rf signal picked up

Changing receive mode
1. Press FUNC + MODE
2. Use rotary control or arrow keys to select receive mode 3. Press ENT to accept change or C/AC to cancel

The FT-840 uses a die-cast RF power amp with thermally switched fan to ensure full power output (up to 100 watts). The digitally synthesized local signals ensure clean, low-noise transmitter output on all HF amateur band. There might be no AC line interference. it has strong Rf output. any AC line intersect does not affect its radio performance. Check and adjust RF power so to maintain proper output. some times more RF power generated at the output may cause interference. adjust Rf power..Even some unfiltered Noise getting the other end of the end may calso cause interference. Check for any Ripple voltages present at the output. Contact authorised service station for further Rectification. thank you shanth

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

The auto scan feature scans the various channel frequencies looking for a signal. Weak signals may be picked up on one scan and missed on the next. Check your antenna or add a antenna power booster and try again.

you have a output speed sensor cuircut issue, scan tool would be helpful for this repair, but here goes, the sesor return wire is picking up rf interferance, in the harness, start by searching front of trans , to side fender to tcm, in wheel well area to over wheel well to bulkhead, possible corrsion as well. GOOD LUCK RDJRP

i recently bought a uniden bc72xlt and had no freqs. found some for my area at these sites.try www.scanner master.com*-frequency resources and home of police and call,www.radioreference.com,www.bearcat1.com,hope some of these sites help you out.

This sounds like a hookup or programming problem.

The typical hookup is cable/satellite box output to VCR antenna/RF input, then VCR antenna/RF output to television input. Since you are able to watch pre-recorded tapes, the latter is already correct. There are other ways to connect, using the audio/video outputs of VCR to audio/video inputs of the TV. Older or low end TV sets may not have these connections.

If by chance you are using an outdoor antenna (not cable or satellite) then the antenna connects to VCR antenna/RF input and VCR output as above. You will also need to program the VCR into the stations- most late VCRs will scan for active channels, and program themselves to those channels.

I'm not sure of the capabilities of newer cable & sat boxes, but generally, you had to tune that box to the channel you wanted to record. The VCR is set to channel 3 or 4 depending on the output of the cable box.

Lastly, most VCRs of the last 10+ years require the remote to setup advanced functions, such as timed record, date & channel setup functions. The buttons on the VCR itself only do very basic functions, Stop/Play/Rewind/F-forward/Eject etc.

If you don't have the orig. remote, some universal remotes may be able to do advanced programming functions.

I'll just tell you how to set it up with an RF cable.

1: Plug the power adapter in an outlet and plug the other side in the designated spot where it fits. Simple.

2: On the back of the SNES, there should be a switch that says channel 3 or 4. Whatever one the switch is at, it will be the channel to play it at.

3: From where it says "NES CONTROL DECK" on the RF switch, plug that into the SNES.

4: From where it says "TV" on the RF switch, screw it into the supplied ports on the TV. Note that newer TV's don't have this port.

You probably don't need to bother with the antenna port.

Enjoy the SNES! :)

Yes if the unit is capable of picking up cable, there is a channel setup menu in the main menu. You half to switch it over to the cable mode. it should be in the owners manual. Good Luck
