My cable connector broke and now I don't have sound even though I can attach it just enough to get a good picture. Any help to this situation?


one idea is to use a vcr to feed the signal into another input. this is not perfect but you can tune in the channel using the vcr as the tuner. the tuner can be replaced or rebuilt depending on the amount of damage. this is very common and as a technician i do about 2 of these a week.

Broken tuner


If the board is not cracked,a qualified technician may be able to sloder another coaxial jack for a service call charge. Look carefully with a flash light........if you see the small board is cracked.....it will need the tuner and could cost $200. You may be able to cicuimvent by hooking your cable box or satellite box into the video inputs instead......select with input button on remote and should work fine with no repair at all

Where can i find a cable for my HDTV (the kind that get screwed in)cables? its a Mitsubishi WT-46805


Hello sounds like the coaxial connector has come off or broken off the tuner, You can repair this problem using the old connector that broke off by taking out the tuner and resoldering the center pin back to the tuner board (provided the small tuner board is not cracked) and the out side of the connector to the tuner housing for ground. If you are just using or referring to a common coaxial cable to purchase, you can get these from everywhere Radio shack, Fry's etc. Also ur local cable company. If all else fails use the rca output jacks from the cable box if u have one and connect it to video input one on the back of the television, make sure you change you television input to video one if u decide to do it this way.

The coaxle broke where you put the cable line on


The coaxial connects inside the set to the tuner. It needs to be resoldered in to the board & secured on the outside to the tuner. Its a quick fix at any tv repair shop. Unless u tried stick something inside & damaged internals of tuner

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.

Cable plug broke off


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.

The silver box is called the TUNER. Call an RCA distributor, such as Union Electronics or Herman-Panson and order it by description by asking for the tuner for your model number. Have the location number on the board, just in case.
