SOURCE: Attach new antenna wire to tuner (Funai TV VCR combo )

If you take off the tuner cover you should see where another wire was attached to the PCB as there will be a small hole with nothing connected and a piece of wire at board level or broken level with the Printed curcuit board. If you dont see it then the best thing for you to do is to send the tuner to a tuner repair place like PTS tuner service and they have a flat rate to overhaul tuners and assy's or see how inexpensive a new tuner assy is. Its available at pts electronics for 49.95 along with many many more items like rebuilt printed curcuit boards ect ect Good mluck

You need an 800 degree soldering iron. It is advisable to tke this to a repair shop. A qualified echnician may bae able to repair the turner without further damaing. It is likely if you try to do this yourself the tuner will be damaged to the pint that it will have to be replaced which will mor than double your repair cost.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope it may help you;

My brand new LG 47LE5400 has no audio

I would verify that the volume control built into the television will not turn the volume up or down. If it does then the remote is causing a problem. If the button on side of tv will not raise volume up or down, I would contact the place where the set was purchased and have them either send out repairman, or either give another set. I guess this would be pretty much up to you since it is a brand new television. Hope this helps.

Hi A couple of weeks ago, the image on my Samsung LN46A550, started to become saturated with green. The image and sound is fine, except that everything on the screen, including the TV menus, which now...

It will be good to have a ccheck within and see if there is any visible indications of failure. check if power capacitors have bulged out if so replacce.
But I thnk the possible fault can be soldering faults/problems in the drive/converrgence circuits.
Dry soldering is the greatest enemy and I think that the parts exposed to heat / cool in due course of time have the drying of the solder.
So use a good iron carefuly not to bridge circuits but to solder suspeccted joints. IC pins and connector joints. use good quality solder with good lighting .
comment and credit if this advice helps.

Sometimes the color stays, sometimes the picture is in black and white?Sony WEGA Trinitron with TimeWarner cable box.

that problem is very common in a sony TV the main cause of that problem is the video can replace it with a new I.F. just adjust the I.F. to do it open the back cover of your can see the tuner soldered on the pc board.using a soldering iron and a desoldering pump take out the tuner from the board..remove the stainless covering of the tuner and soldered it again to the board there are two IF(intermediate Frequency) on the tuner the sound I.F and the Video IF.After soldering the tuner to the board power on the tv and use a plastic jewelry screw or an alignment tools then turn clockwise/counter clockwise gradually and slowly untill you reach a good carefull when adjusting not to touch with your hand the high voltage section...good luck hope I helped you Please vote for my help.

The coax connector broke off the back of my tv ineed a new part were can i find it

hi i will be more than willing to try and solve your problem. this problem can be costly, because you will have to reconnect the copper wire to the circuit board on the inside of the tuner. if you do this it still might not have a good connection. sometimes the set will not show as good and have fuzzy channels. you then will have to resolder the outside of the coaxial to the tuner this has to be done right or it will be easy to break off again. it is best to simply get another tuner. when i have this problem i just simply go to tiptop tv. the whole tuner with shipping and handling is about $31. if you have some soldering experience you can simply desolder one and solder the other without paying anything extra. you must have the number on the side of your tuner or even have the brand and model number of your tv and they will be very helpful. i have used them for years and they have never let me down. i believe that this will solve your problem. please rate me on my solution. thank you and have a nice evening.

My RCA F31672ET is messed up, what can it be?

These unit are notorious for bad solder joints in the tuner unit. If you unplug the tv and remove the large PC board, flip ot over and you will see a large silver oblong with 3 solder points. de-solder theses and removed the cover from the tuner. Re-solder the connections along each of the sides of the oblong shaped case.and you will also see some ground pins which also need re-soldering.
put the cover back on and you should be good to go.

As always, exercise caution , Televisions can hold a charge on some of the capacitors for quite a time and can shock you even after it has been unplugged for a few mins

Coaxial outlet broke off

I assume that you pulled the F connector out of the back of the TV. In most Sharps, the F connector is attached directly to the tuner, which is the rectangular silver metal box soldered to the main PC board. Did you buy a replacement F connector or the entire tuner? Either way, the tuner must be unsoldered from the main board and the new F connector is soldered into the old tuner or the new tuner is soldered in its place. If you do not have experience soldering PC boards then let a qualified tech handle it for you.
