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.
On most TV sets, the cable connector (also called an F-connector) is just press-fitted into the metal housing of the tuner (which selects the channels). It's not very strong mechanically and is pretty easily broken by tripping over the cable, moving the TV if the cable is too short, or often by cable technicians who overtighten the cable connection with a wrench.
The good news is that this can be fixed. There are two ways. The simple method is to replace the tuner. It's quick but costly as a new tuner may run $100. The second way is to replace the broken-off F-connector. On some sets it's possible to do this without removing the tuner, but not always. This repair may take a little more labor time, but saves the cost of the tuner.
Either way, this is a repair that's best left to a professional. Without the soldering skills and equipment needed, it's possible to do major damage to the TV and tuner circuit boards. I would recommend getting an estimate for the repair from a shop in your area. Yes, there are still places that fix TVs, but they are getting scarce.
Another possible "fix" is to forget about using the TV cable connection and use a VCR or DVR to tune the channels, and just use the TV's video and audio inputs. It doesn't repair the TV, but it gets you back onto the cable.
I hope you've found this helpful. Thanks for using Fixya!
The small metal box is the tuner. The tuner has to be removed to replace the broken off RF connector. The connector has to be soldered to the tuner housing (metal box) and the leg of the connector has to be soldered to the circuit board, board has to be checked for cracks or if it is broken. If board is damaged the tuner will have to be replaced, if its available.
The cheapest way i can think of is open the tv and solder the ripped peice back on. That should work. If not you can go to radio shack and buy a new peice for it and install it by soldering the connections back on. Hope I could help.
A careful visual inspection is the way to start. Examine the circuit board(s) carefully for cracks. This may require removal of the board & a magnifying glass. Inspect the connectors where wires enter the board, & pay careful attention to the areas around heavy components. Any cracks found must be soldered where they cross the copper traces on the board. The green coating (solder mask) must be scraped off prior to soldering. Most likely the damage is confined to board cracks, as most solid state components are pretty rugged & not subject to impact damage. Use extreme caution around the high voltage area, as the set may retain high voltage even when off & unplugged. The high voltage area is that around the thick wire that goes to the suction cup on the picture tube itself. If you are not comfortable doing on-board repairs, call a qualified technician to do the repairs.
What you are calling the "antenna module" is actually the tuner. The connector that pulled out is called the F connector. The F connector can be soldered back onto the tuner but this is a very delicate procedure and is especially difficult if any of the coils in the area of the F connector have been bent, altered or moved. The tuner itself is not too expensive and is much easier to replace than trying to replace the F connector, especially if you have never done one before. If you use this set with a cable box then simply connect AV cables from the cable box to the TV set the TV to VIDEO.
Unless you know how to sholder well and know how to do an isolation test on the set after its repaired I would let a pro do it My friend as I've seen it a hundred times. A peep will simply hook up a connector to the set and ground the connector or what looks like a ground and as soon as that set is pluged into an ac outlet and a cable or sat line is attached KAPOWWWWEEYYY.. It smokes and you end up blowing out the bridge rectifiers aong with all sorts of things. Now dont get me wrong please as you can repair set if and only if you wanna take that chance by simply taking a piece of coax cable with a connector on one end and soldering the center wire onto the broken wire that came off the connector and then soldering the outside or sheild wire to the place where the broken connector was attached if at all possible BUT I repeat this is not a good way to do this. Good luck
