There seems to be an incompatibility between the TV's setting and the antenna's input.
The TV doesn't see the antenna connection and keeps searching.
Somehow you have to get the TV's 'cable' setting in the menu to 'over the air'.
Is there a clean signal coming to the TV? Sometimes a cable can be compromised where the signal never reaches the input connection. Check both ends or at least replace the cable temporarily.
Last but not least, the TV maybe set to a PIP (secondary tuner with a picture in a picture) and the tuner is not electronically connected.
A snowy picture after warmup is either in the set or not.
What you may want to do to begin with is hook up a DVD player or something else to ONE OF THE VIDEO INPUTS ON BACK OF SET this will narrow it down to the tuner or the front end of the set.
If A/V hookup works you always have the option to hook the output of the cable or sat box to those same kind of rear connections- bypass the tuner and front end signal circuits completely.
As it only happens when on a short time not likely to be a hookup or bad connection there but check them anyway.
If using a box of some kind run the cable or sat direct without it--bypass the box to rule it out.
Last is if tuner in set is bad it would have to be removed and or rebuilt/replaced---not cheap parts and labor
Your cable system is probably QAM (digital cable). The tuners built into the TV are analog and digital OTA tuners (ATSC and NTSC). If you connect the Cablevision box to the component video input (and connect the audio out of the box to the appropriate audio in) on the TV and an appropriate antenna to the coax (antenna) input, you will be able to swap use the tuners in the TV. (See tvfool.com for antenna types and direction or antennaweb.org for directions of the most likely stations to be received at your location. antennaweb assumes an external antenna and is conservative in the list it provides.)
I hope this helps.
Cindy Wells (please note, you probably need to get the component video cables. These have 3 RCA plugs on each end (red, green and blue). To carry the audio you need a cable with 2 RCA plugs on each end (red and white). Match the colors as you connect them.)
If your Sharp television has RCA jacks, you may use them through your VCR. Your VCR would have to have a tuner and then you may use this as a means for getting a signal. Newer VCRs and DVD players generally do not have a tuner. Thanks for asking!
Sometimes you can replace the rf connector by resoldering it with a replacement rf. You will have to remove the tuner to do this. The big question is did you crack the tuner board or the board the tuner is connected to. You will really have to examine these. In most of my cases a successful replacement rf connector will fix.
Well first repair the coaxial cable going to your antenna. There is no way you can use RCA cables as a substitution for coaxial cable. They have totally two different properties. You can use the coaxial and feed it to a VCR/DVD player where you can output the signal with RCA/composite cables. Basically, use your VCR/DVD player as a tuner for your TV.
Erica,
You should have no problem with this. I have provided a picture of your model below for clarification. One end of the coax will attach to the 3-4 OUT on the back of the receiver and the other end will go to the NEW tv's coax input. If your set has two coax inputs you may have to select the port that you connect to in the menu portion of the tv. If the new tv does not have a coax input you can use RCA jacks which are red/white and yellow and connect those to the TV 1 output on the back of the receiver and the other end to one of the inputs on the back of the tv- this will require you to select the input source you connect to again e.g AUDIO 1, AUDIO2 etc. If you have a VCR run the coax from the 3-4 on the back of the receiver to the antenna inon the back of the VCR -usually the top port, then run another coax from the output- bottom port to the coax input on your tv. I hope I have been of some assistance to you and Thanks for using Fix Ya. If I can assist you further please let me know.

You have to re solder the connector. The other solution is to patch from the Direct TV box AV out to the AV input on the back of the TV. This will bypass the tuner and give you a cleaner picture. However, if your TV does not have an external input you must re solder the connector. As easy as it may seem, this should be done by a qualified technician. Its not as easy as it looks and requires good soldering skills.
You didn't mention anything about a cable box, VCR, etc. which might be connected. A snowy pic. means simply, inadequate signal is reaching the tuner, or the TV tuner itself is bad. If the first is so... check your cabling. If you have a VCR or DVD player hooked in between the cable box or outside antenna (whichever is the case), VCR (RF or ant.) out should go to the TV, VCR antenna (RF or ant.) input to the cable box.
Also check the cable wire itself. If you look at the end of the cable, you should see a relatively thin center wire. This center conductor is what carries the signal. If it is missing, bent over, or too short to make contact with whatever it is connected to, you will have a very snowy pic.
If you have a spare TV, connect it in place of your "new" TV, to narrow down the problem.
Lastly, if all is well with hookup, cabling, etc. the TV might have a problem. Sometimes the tuner has a component defect, or the coaxial connector can be broken.
Was the block a cube about 1" ? You should be able to salvage one from an old tv. This block is used to isolate the antenna/cable from the "hot" chassis inside your tv. If you should find a used block ,make sure it does this. If you get one that gives you a direct connection to the chassis, your antenna/cable connector would give you a shock and probably burn out something in your tv when the cable is connected.
Some of the Sanyo's have this connector made on to the tuner. If this is the case you'd have to either put a new coax connector in the tuner OR replace the tuner.
