I have a 42panasonic plasma tv model#th-42pwd7 it has no cable antenna terminal in the back of the tv but it has rgb terminals i have a converter box and x box360 how can i get a antenna tv signal

Its a Progressive Wide Plasma Display. It wont have a built in Turner. So you will not be able to connect antenna to the TV.You have to use a set top box or cable box and connect its output t the TV.
If you wish to get some details; check the site linked here. Pull up older posts.

I just hooked an antenna to my sony bravia and it only picks up a few digital channels. I have two other Tvs hooked to the same antenna and the both pick up so many more channels. What could be the pr

i think the 'front end fet' or channel fet has failed
this amplifies the incomming antenna signal
however is the center pin of the antenna plug on the tv loose
inside the tv is a metal box this is attached too
it changed the UHF signals to a lower frequency range called an IF
the UHF signals are normaly have a path like this
antenna>>safety >>>amp>>mixeramp>>output to DTV decoder etc

the amp bit or connection to the tv is wrong
as its working quite well and gets like 2 channels

look inside the socket on the tv and examine it carefully for any bits of wire
or as i say loose connections
may just need to be soldered inside the can to reconnect the center pin

it will still give like 2 3 channels as the gap caused by the bad solder joint
will still allow some RF accross
so... its either a gubbed UHF RF amp or a broken connection or a short ... so...

I want to extend the aerial wire by 6m. I have attached co-ax plugs but the picture is breaking up.

Probably because there may be a bad solder joint or connection in one of the connectors. Did you solder these connectors on or is it a screw on type of connector? What you can do is to gently flex the cable at the connector and see if that makes the picture break up. If it does then that is your problem and you will need to solder them. By the way, it is no longer called an aerial but rather an antenna.

I have been a lisensed ham radio operator since 1958 and have soldered hundreds of connectors to cables. At that timewe used to call them aerials.

Good luck,

No signal stuck on channel 2 with black screen. Model KDL37M3000

Are you connected to a cable or sat box, Are you connected thru antenna input on tv or a/v input. If connect to box thru antenna jack of tv do channel search to pick up ch 3 if box is set to that. If connected to outside antenna still do channel searsh but be sure tv is set to antenna. If connected via av or hdmi the cable or sat box is bad.

It's either a bad antenna cable (most likely), or the F-connector socket is broken or has come un-soldered inside the se (possible)t. First, try exchanging your antenna cable with a new one. They're inexpensive and tend to fail over time anyway. If that doesn't solve the problem, a technician will be needed to repair or replace the F-connector (the screw-on connecter where the antenna connection screws in on the back of the set). If you're good with a soldering pen and have a nearby electronics store where you can buy a new F-connector socket, you may be able to do it yourself, as it's a very simple repair. If you do not have the skill to make the repair, don't fear, it shouldn't be very costly to accomplish.

Your flat panel TVs picture tube base board has soldering loose contact with it. Just unplug your TV from AC mains socket, and open it. Pull out the picture tube base card from the picture tube neck. Pull it out straight, no shake must be there, as it will damage its connecting pins.
Normally, loose sodering are very difficult to loacate, as they will be quite micrscopic in size. Just resolder all the suspected loose sodering point on that board, by applying a little more solder. This will solve your TVs problem. OK.

Antenna Connection Pulled out of TELEVISION & cannot connect antenna to Television.Television will not play as

Use composite input or any other available input other than the tuner. If you know how to solder, get a new connector and solder it in. If not, take it to a technician and have them repair it. This is a minor repair and should not cost much as long as you didn't destroy the board itself.

Green tinted picture

if it's intermittently losing the red you probably have a bad solder connection on the red picture tube board, if you have solder skills you can pull the board off and solder any bad connections to fix it. you can tap lightly or flex on the red tube board to make the red come and go to verify the problem.

Have audio through all inputs except cable

Sound like you may have cold solder joints in the antenna connector. This may be a simple fix of repairing the connection points. If the television is still under warranty you will want to let the service center fix it.You can reach the Dynex customer service at this telephone number.1-800-305-2204 between the hours of 7am-12am CST. Give them the model number of your television and the problem you are having with intermittent sound from the antenna hook-up. If not under warranty, you will have to either do it yourself or have someone do it for you. You will have to remove the back panel and repair the bad solder joints. This will require a bit of technical know how. You will have to have a set of screw drivers, plastic pry bar and a soldering iron. You will have to remove all the case screws and then use the plastic pry bar to unlock the plastic case locks. You can unlock these locks by using the pry bar. Pushing it in the case and sliding it along the sides to open the locks. This must be done carefully or you will break the locks and the case will lock to- gether correctly. Then you will have to find the input circuit that the antenna connects to and rework all the solder joints. Add new solder to joints to make the joints strong again. Then test the unit and see if the sound comes back.If not you will have to look over the other parts of the circuit and see if you can find any other faulty joints and repair them. remember to never work on the television with the power on. You must be very careful working on the board. Do not touch any capacitors or other components. You may get a shock or give them a static electric shock and ruin the component. Try to wear anti-static wrist bands and gloves. This should be a simple repair for a experience electronic technician. If this does not fix the problem then you may have a more serious problem with the audio pickup circuits. That will require a service center to test and repair. I hope this information helps you with your problem.
