A friend gave me 50fx48b projection tv from his bar. I got it home and noticed the coax cable was somehow ripped out taking the screw part that goes into the tv with it. Can it be fixed and if so what are...


If all that's wrong is the coax jack on the back of the TV is missing, you need a "female panel mount "F" connector". You should be able to buy it at Radio Shack. How to connect it to the remaining wire will depend on how the internal wiring was done. If you aren't handy, and there is still a stump of cable showing, you might be better off buying a cable with a female end, cutting it off and then splicing the cable end to what's left in your TV. Look for YouTube videos on splicing coax cable. Either way, you will have to understand how to handle the center conductor and the shield. If you wind up working inside the TV, make sure you thoroughly understand what you're doing to avoid injury.

How to fix the antenna anolog cable connector that to coax cable connects to on back of TV.


Cut off the bad connector on the end of the coax cable. Go to Radio Shack, Home Depot, etc. and pick up a new twist-on coax connector, or a crimp on version if you have a crimping tool.

Twist the new coax connector on good and tight and you should be good to go.

Yes there is a possibility that something shorted... remove the cable wire and unplug for 10 to 30 min and try plugging back in and restarting the set. otherwise the tuner probaly would need replaced. something any tv tech can do. AT the shop we replace these conectors al the time. just depends how bad the tuner is damaged.

Broken coax connection on back of unit


If you are comfortable doing some small repair work, you might be able to fix this with stuff you have laying around.

All you need is:
1 - 8" piece of coaxial cable with male connector on one end
1 - set of RCA cables (Red/White/Yellow)
1 - coaxial coupler
2 - small wire nuts

electrical tape

Take the back housing off of your TV. You may have to unscrew the small nut holding the threaded connector to the TV. This threaded connector should connect to the motherboard with a male RCA prong that should be soldered to the component on the motherboard. You will need to carefully cut
& remove the old soldering & wiggle the connector off. This is the hardest part, but it WILL come off with a little trying.

Now get your coax cable and strip off about 2" of the black outside housing ONLY. Your solid copper` interior cable should be protected by a small plastic coating which is covered in braided wire. You'll need to be careful not to cut the braiding off. Untangle the braiding down to where your cut stops and try and get it all on one side of the cable so you can twist it all together and make a nice wire. Now strip about an inch off of your interior plastic sheathing to reveal the small solid copper wire on the very inside.

Get your RCA cable and cut about 6" off of the one yellow side. Follow the same process above to get a braided sheathing wire and a solid copper wire. Attach this yellow wire to the coaxial cable by twisting the two braided wires together and the two solid copper wires together. Use your wire nuts & electrical tape to secure your connections making sure none of the wires can touch each other.

Connect the yellow cable's male prong into the component on the motherboard and attach your coaxial coupler to the male end of your coaxial cable. If you saved the small nut from earlier, you can re-attach this new coupler to the housing on your TV. Screw your housing back on the TV and you should be good to go.

I have a panasonic DLP rear projection t.v. There are bright colored spots on the screen. the screen has ghostimages and vertical lines.


Ghosting is usually caused by RF interference.

I would troubleshoot the video source rather than the projection TV.

The first thing to check with interference is the tightness of all connections. If your signal is transmitted via a coaxial cable, (which I'll assume because ghosting is common with coax) use a wrench to thread each connector tighter. Not too tight, of course, just a little more than what you could do with your fingers. Check the image.

If ghosting still apears, check the connectors themselves. At any point can you easily pull the cable out of a connector? Does the cable look like a good quality cable? If the cable itself is thinner than a standard pencil, the answer is no. A lot of manufacturers turn out crappy thin coax cables that cause many, many problems.

If you're pretty certain the interference is not attributed to bad wiring, consider the environment where you watch the TV. Are there devices within range that might cause RF interference? A CB radio? cordless phone? cordless microphone? microwave oven? wireless router? If so, these devices might be resonating with the video signal, causing the unwanted equivalent of a delay in an audio signal. Try unplugging these devices one at a time and observe what difference, if any, they make on your reception.

Report back if these tips are not fixing your problem.

I broke off coax cable on back of 32 inch tv. I can watch dvds with AV cables but not cable TV. How do I connect cable from wall to tv if coax is broken off


This depends on how many available inputs you have on the back of the set. If you have more available you can just hook up the cable box composit (yellow, red, and white cables) if not you will need to replace the rf connector or tuner in the set. let me know if you need more help.

Hook the cable up to the VCR or if you don't buy a RF converter from radio shack or electronics store which will have a coax connector on it with component and Svideo to send to the TV. Select the connection (Component or Svideo) in the TV menu. If you only have the coax connector on the back of the TV without any other connection, you will need to get that tuner board replaced.

Mitsubishi rear projection no picture and static sound


I assume you are using a cable input, such as a box or the main Cable line connected directly to the TV. examine the main Cable Coax, look at the copper wire that sticks out from the connecter, make sure it is long enough, if its to short, gently pull it with a long nose plier until it reaches the rim of the connector. Sometimes when connecting the coax to a source, the copper wire in the coax is to short to make contact, and as a result you get no signal. Hope this solved your problem.

Hitachi 50UX23K blows main fuse when just plugging in coax or anything in back


You may a grounding (short) on the coax connector on the set. The connector should isolated from ether side of the AC input of the set. Take a ohm meter, set it to 1K. and test between the coax connector (both the shell and center pin) to both sides of the AC plug. You should get NO reading! If you do, their is a short. (The coax cable is grounded where it comes into the house). As for the relay, try Fry's electronics.
