The RF jack is solder directly into the tuner module and as long as it did not break the circuit board inside that it connects to, it can be repaired . Takes a lot of heat though to solder the jack to the frame of the tuner. Sometimes I use 2 irons to get it hot before the plastic guts of the jack melt too bad. Also is sometimes hard to cram the jack back into its mounting hole, may need to file it out some. The makers don't solder these on they are just pressed in and crimped which is why they break off so easily. I recommend using the push on type cables to avoid this problem. Don't forget to solder the center conductor into the tuner board.
Hope Ya Fix It!

How do I adjust the screen geometry?


Important !
After you get to the item that needs adjusting
Write down the original setting
just in case you have to go back.

1. TV unplugged
2. Press and hold the'Vol down' and 'channel up'
3. While holding the buttons, plug in the TV.
You are now in the Adjustment mode
You will be presented with a category menu containing.
Fix Value
4. Use the 'Channel up'or"Channel dwn' to select the category.
note:Not all models will have 5 categories, some will jump to the 'Signal' category.
5. Use the 'Volume up' to enter the category.
6. Use Channel up and down select the item to be adjusted.
7. Write down the old value of the item before changing.
8. Volume up and down adjust the value.
9. When you have made all the adjustments you want turn the set off to exit.

Data sheets are available for most models. These sheets list a description for each
item as well as data range and typical settings for your model. If your setting is
substantially different than the sheet then you may be developing a problem.
you want to go into deflection mode and look for pincushion items i.e pin amp,bow etc. AND don`t forget to write down original values

Tv will not come on , some guy came out and said its the low voltage pwr supply, whats the cost of the supply, what does it look like and is it easy to replace if you know how to handle a soldering gun, tv...

just take your tv to a near w/shop, and ask a tech, to check components, on the power supply.
components like transistors, diodes, ic if any on thepower supply,all eletrolitic capacitors values, and change all changed value capacitors. because if capacitors change values they change oscillation hence increasing current output.
if you do that your set will come back to life again.

Closed Caption-disable

I cannot find a permanent solution for this problem. All I can find is to press the cc repeatedly until it says off or mute. I looked in the book.
Sometimes cc will come on during a show. I think it is certain channels (abc) makes it come on certain shows and you will have to cycle the cc button again to make it go off. The Mute setting will make the chosen language come on when you press MUTE.
Spanish comes on mine unless I change to cc1 for English if I want the cc working.

Lynda, could be why someone was selling it? It could have a bad connection inside the set somewhere that needs to be addressed asap as it will get worse, or a power regulator is bad. This will oneday make the set not turn on anymore without a repair job. Also make sure the outlet your pluging it into isent loose. Sorry i couldnt assist you more with this. Good Luck
