The easies and cheapest way is to use the audio video input. pulg the cable into your vcr & use the vcr to change channel. the other way is to replace the tuner, typically tuners sell for around $75.00 to $100.00.

That sounds like a problem between the antenna and the television. First off, be certain the antenna is aimed properly. If there is any equipment between the antenna and the television, bypass it for the time being and run your cable directly to the television. If the TV still won't detect a signal, connect it to something that outputs a signal on analog channel 3 or 4 and scan for channels again. If still nothing the problem is most likely in the television. If you do get a signal from the device you use to generate analog 3 or 4, then the problem is an inadequate signal from the antenna. Check the connectors on both ends of the cable for secure fit and stray shield strands which can sometimes cause a short circuit to the center conductor at the connector. Be certain that the shield conductor makes good contact with the outer part of the connector. If your antenna system requires an amplifier make sure it is connected to power. If the amplifier is a mast mounted unit make sure the power injector has no splitters or other devices connected to the cable between it and the mast mounted unit. Check for defects in the cable itself. If the cable is routed through areas of your home that prevent inspection you may want to run a new length of cable, at least temporarily, to verify that the existing cable is or is not where the problem lies. RG6 or RG6 Quad cable is recommended for proper resistance and shielding values. Once you get the signal back, reconnect any equipment you bypassed earlier ONE AT A TIME. If you lose your signal after reinstalling something then that item was a part of the problem. Good luck!
Tv fell off about 3 feets or more?Yes,turn on the tv see if u getting any power to the unit?Might have broken main PCB board too.If unit still have power,check see if tv get statics screen have colors shaded in red or mutiples colors,mean the tv CRT(tv tube) yoke is dead and damages scrambles radiation.Or the tv getting power but have high pitch sqeeling noises or rattles noises,tv have the CRT-(tv tube) is crack by the neck or broken totally.CRT have damages problems or dead tv is worthless,beacause of CRT(tv tube) is dead,not fixable even that antena connector input is replaced.
These sets have what is known as a on board Tuner. This means that the Tuner is not replaceable without replacing the entire Board. The good news is that you can replace the Cable/RF connector as long as the shield it attached to is not broke or too bent. Most of the Cable/RF connectors used in these sets have PCB mount . You will have to remove the Signal Board and unsolder the center connection of the broken connector left on the Board. Remount the new
Connector and solder the center connection. You may need a collar nut to secure the Connector the the shield.

It depends if the connector broke the tuner it is attached to. Most times the chassis of the set would need to go into the shop. I would generally charge $80.00-$120.00 if the tuner was still good - a new tuner would cost $60-$100 more if bad
The better solution is to use the video audio inputs (if on satellite or cable box) or use the video inputs by changing channels through the VCR (if on cable or antenna and a VCR is available)
Doubtful, though I've not had one with a gimped antenna so I can't say for sure...
Probability is very high that failure to start is related to the ribbon cable(s) not being seated properly into the connector(s). This is a common issue during re-assembly. Often, these cables LOOK like they are re-seated properly - but they are not.
First suspect is the ribbon cable that passes through the hinge. Where it connects into the top board is where I encounter problems often. If this cable is not seated deeply enough into the connector - and perfectly perpendicular - your reassembled DS will NOT boot.
I always temporarily snap everything together and test boot prior to screwing everything back together. Even with care and experience I have to go back to this connector and re-seat the cable about 1 out of every 2 times.
If you have already identified where the connection was on the board you will have to access the board to be able to solder back to the points where the old connector was. Once you have identified the two solder points (One should go to ground and the other if you can with the tv on touch it and see if a picture tries to come in or get rid of the snow). Then buy a matching transformer from radio shack or Home Depot, Lowes. Normally this would go on the outside antenna. But you want to take it and clip and strip the ends that have the forks. Solder this to the board, one to ground and the other to the point that would have been center on the old broken piece. This will have a 72 ohm or a connection that your antenna will connect to.
If the connector end is not damaged and the tuner circuit board is not broken, you can solder this back onto tuner, and solder the end back on the circuit board. You should take the tuner out to do this proceedure. A TV shop usually charges $50.00 to do this.
You can buy replacement antenna jacks for this. What you have to do is remove the tuner and it's shields, then unsolder the little tab off the board of the tuner which is what remains when they break off. Then you can resolder the new jack in place and the center pin back to the board of the tuner.
