Usually this is a bad cap in the vertical circuit or a failure of hte vetical IC. If you can post the make and model number, I should be able to provide you with more details.

Thanks,
Dan

Why are the movies half screen?


Movies that are created for "Wide Screen" viewing show up in letterbox on your TV. If you go to a theatre you notice it is a big rectangle. To be able to fit all of the widescreen movie on a TV it has to make the height smaller.


Because many people want to see the "complete" Movie, the "Letterbox Format" came about. I do NOT know what the word "Letterbox" actually means, or how that term was chosen. To get the complete Rectangle into that Square, they discovered that they could shrink the entire rectangle to fit that square. Meaning, what used to take 2 inches on your screen, now may only take 1.75 inches. Now a problem arrose. When you shrink the WIDTH to fit your dinky Square of a TV, the HEIGHT also has to be shrunk along with it, or else you're stretching the image as if it was on silly-putty ("Compression"). When the image was shrunk to fit the TV Screen, they were left with a gap at the top and bottom of the screen. So they simply fill it in with "Black". I guess the only alternative was to leave it snowy.

Can sirius antennas be cut and spliced back together




If your antenna cable has been cut or severed, it can be repaired without the need for a replacement.

You will need the following things:


Small 600 degree soldering iron and solder.
Liquid flux for soldering the braid.
Small sizes of heat shrink tubing.
Small heat gun.
Small pliers, cutter, and Xacto knife.




1) The first step is to use the Xacto knife to cut both ends of the antenna cable so you have a clean end.

2) Using the Xacto knife roll the cable on a board and gently cut all around the cable to cut the outer insulation. Remove about 1/2 inch of the insulation from each end.

3) Push the braid back to expose the center wire and gently roll the cable and cut the center insulation to expose about 1/10 inch of the center wire. With your small long nose pliers, bend the center wire into a small hook shape.

4) Repeat all the above steps on the other end of the wire.

5) Put a 1 inch piece of heat shrink tubing on one end ( the black piece), and a 1/4 inch piece of heat shrink (the white piece) on the center conductor. Look at the picture to see this.

5) Hook the two ends together. Gently squeeze the hooks closed and solder them together. Be very careful when soldering this. Be quick so you do not apply to much heat and cause the heat shrink tubing to shrink on the side where you do not want it to be.

6) Slide the small white heat shrink to cover the cooled solder joint you just made and use the heat gun to shrink the tubing in place.


7) Now push the braids back together to cover over the connection you just made. Try make the braid smooth together by GENTLY rolling the cable between your fingers. Carefully solder the braid. A little liquid flux on the braid prior to soldering helps the solder flow and makes it look better.

8) Slide the final piece of heat shrink tubing over the braid and shrink it with the heat gun.

Picture Shrinks


It is in the power supply or I would guess most likly in the horizontal sweep section of the tV set. MOST of the time, if the power supply is going lower in voltage, the set will shrink in width,BUT will also shrink in vertical size. If this is not happening, then I would say it is in the horizontal drive circuit. This is not a circuit a user should be experimenting with, as this is the HIGH VOLTAGE circuit and can pack a mean punch! Please if the sets less the 4 to 5 years old you may want to concider an estimate or replacing the set. Its all up to you. GOOD LUCK
