Question about Sony FD Trinitron WEGA KV-20FS120 20" TV

2 Answers

No cable When I plug the cable wire into the VHF/UHF port on my Trinitron, it yeilds no signal. I'm capable of getting a signal by running the cable into a VCR and plugging the VCR in via the three pronged A/V connections, but I obviously must change the channel on the VCR. If I plug the VCR in via VHF/UHF I also get no signal, nor can I play VHS tapes. I wonder if my VHF/UHF jack is broken, or my tuner, or both? What are my options for fixing this, without spending buckets of money?

Re: No cable

I have the same situation and in the tv/menu changed the settings from digital to analog and now I get a limited number of channels, probably just the analog ones since I have cable service.

I have an rca G36705 and I just need to know if it has a digital tuner or if o need a converter box to hook an antenna to it?

Its inputs include "Composite" and "S-Video".

Itttkk Its *ANALOG* tuner has channel coverage:
VHF:2-13, UHF:14-69, Cable:1-125, VHF:2-13, UHF:14-69, Cable:1-125

So, you will need a digital tuner.

Digital or Analog tuner

Your Apex TV model have the tuner which is capable of receiving
VHF 2~13/UHF 14~69/CABLE TV: MID BAND(A-8~A-1, A~I)


ULTRA BAND(65~94, 100~125)
If the signal of your cable provider do not have in these ranges, you must have toconnect a converter.

I can't get FOX on my converter box--what is the channel # for FOX?

It could be your antenna. Some retailers sold consumers UHF-only outdoor antennas and not VHF/UHF combo antennas. Other outdoor antennas may not have a power boost included for the VHF antennas (rabbit ears). The new DTV signals from stations are now broadcasting in lower power signals than before June 12.

Outdoor Antenna

KMSP/FOX 9 and KARE 11 both broadcast on VHF signals. WCCO and KSTP broadcast on UHF signals. You will need a VHF/UHF outdoor antenna to pick up KMSP and KARE 11 and also get all the other channels.

Indoor Antenna

Check your antenna to make sure it's a UHF/VHF antenna. You may need an indoor antenna that has rabbit ears -- that is the best way to get KMSP/FOX 9 reception on your TV. Your antenna should have a power boost to amplify the VHF signal if you are having trouble getting FOX 9 or KARE 11.

What Antenna Is Right For You?

Make sure you antenna is pointed toward Shoreview, where FOX 9 transmits from.

I get no channels wen i plug in my cable wire into the cable jack


First, I would change the cable that comes from the wall to the TV.
Plug the cable into the cable port, then go into the menu of the TV. Go to the channel setting and go down to where it says "CABLE YES/NO"and change it to cable YES. Then try to re-autoprogram it.

If there are no channels found after that, then you may have an issue with the tuner.

Hi there!

Assuming that you tried to tune stations onto the UHF bandwidth and received nothing,Commonly the tuner box is probably at fault and needs replacement. The VHF and UHF signals are split inside the tuner so if you receive VHF fine then UHF should as well unless faulty of course. Some circuits require an external IC to do the switching, but more on the older models. Regards and good luck, JUS004

No uhf with antannae

UHF channels are basically "line of sight" type signals. You need to be pretty near those UHF stations.
You need a Uhf or combination Uhf/ Vhf antenna to receive them - - Usually an out-door type.
Your TV needs to be set in the "antenna" mode to tune beyond channel 13 "air type" channels. Channel 14 is the first UHF channel if you're in the antenna mode. If you're in the "Cable" mode then channel 14 is a cable channel which is operating at a different frequency from UHF.
I hope this will help you!

No receipt of signal or antenae

Since it has voice or sound then I don't suspect the tuner but probably the tuner does not have the 33 volts that goes through r106 location number on the board. It is a 27K resistor and can be bought for about a dollar at Radio Shack. (pack of 2or3) A repairman or someone experienced in electronic soldering and desoldering can change it easily. Could cost around $50 to repair depending on the serviceman. If it has rca jacks (red, white and yellow) The tuner can be bypassed if you have a cable box that passed these signals: audio left and right and video. Hope this helps

Reception of vhf/uhf channels

You did not mention which set you have, so look for a small switch (usually on the back of the set) or go into the menu and set the TV to the "broadcast" or "tv" mode. If the set is in the "cable" mode, you will not get any UHF channels above 13.
