    cannot get a picture unless male fitting is pulled out so ground does not touch female ground on F27TF700

    The cable does not show any continuity to ground only the input jack on set. I wonder if the jack for the 3 wire hookup is also shorted. This set is ia my trailer at the lake.

There is a problem with either the cable itself or the tuner. I would suspect that there is a broken connection inside the tuner. This set should be brought to a service center unless you can solder.

Let me know what you want to do and I'll supply more info.

Hooking sayyo tv to directv

Not sure if I understand what is happening here but if set on channel 4 the connection for the direct TV would have to be to the coax fitting on the rear of the set.

For the audio/video inputs on the rear or side it would have to be the same ones coming out of the direct TV box to one of the same but inputs on the rear--Audio/video are one connection and coax for channel four is a different one.

Cable input broke

Depends how old the set is and what it cost---the coax input can be replaced most of the time anywhere from 50 dollars and up.

If the set has the audio and video jacks on it you can route signal that way and bypass the tuner and cable fitting with a box or even a old vcr.

I have a jvc interiart tv and when i turn it on the picture breaks up as if i have no signal however my signal is fine and if i turn it on and off lots of times eventually it starts working and the picture...

A few thoughts and a suggestion first.

If using the coax fitting for the signal try connection of any DVD etc to a rear input to see if same problem. This will tell you if the problem is related to the TV's tuner.

If using a cable/sat box/ receiver unplug each and wait a while and plug back which will allow each to try to reboot.

If no issue with the DVD etc via rear inputs you could bypass the whole issue by routing your signal not to the cable fitting but to one of the sets of inputs on rear of set

Let me know what you find and if you have questions.

How do you replace a coax antenna port that was pulled out from the back of the tv

On most sets the tuner has to be removed for this to be done-a new fitting or a new tuner can be installed.

If the set has the standard RCA audio and video jacks for input you can hook a cable box or even an old VCR to those and BYPASS the coax fitting--hook up to those inputs--select them on the set and leave set on that input and change channels with the box or VCR.

Much cheaper than replacing the fitting and gives a better picture.

"no signal" shows up on

You will need solid coax ends and connects. You need very high grade coax union and snap and seal coax BNC connectors for both ends.You also need a RFI filtered surge protector to filter all the AC plugs for the HDMI box. This shoulf fix your problem

I have recently switched to a Dual receiver from Dish network...I have a coax connection to my Sony but cannot find the way to change the input to find the signal from the coax cable. The TV will not take...

We would be happy to help get that fixed right away. Thefirst thing we want to ensure is that all connected equipment is on. Since we know you are using a coax cable to connect the receiver toTV1, check the receiver's back panel for the output name. If your receiver hasa "TV CH 3/4 out":Tune TV to channel 3 or channel 4, if it is labeled "Home Distribution": TuneTV to channel 62 or 75. We also want to ensure that the TV and thereceiver are connected properly, please visit this link to for moreinformation: we have made sure everything is connected properly, unplug receiver for 10seconds then plug it back in, this will reset the receiver. If we are still notgetting a picture connect another component (VCR, DVD Player, etc.) to the sameTV, using same cable, same input, and same channel to see if it works. If youget a picture with the other component give us a call at 1-800-333-DISH (3474)for some additional troubleshooting. If it doesn't work with the othercomponent then replace the cable that was used.

We hope these steps resolve the issue. We want to thank you for being a valuedDISH Network customer!
