This is usually caused by defective convergence ICs, large black ICs mounted on big metal heat-sinks. When they go bad the convergence can no longer be adjusted. Along with the ICs there are sometimes fuses, fusible resistors and voltage regulators (that supply voltage to the ICs) that can be damaged when these ICs go out. Then after all the parts are replaced the convergence has to be reset. This is one of those repairs that should be done at a repair shop. If done wrong a relatively inexpensive, easy job can be turned into a costly one that may exceed the unit value. Cost of repair can range from $200-$500 depending on the shop fees.

American camper tent 2455 setup


Finally figured it out through trial and error. This right here is the only correct explanation given anywhere on the net.

First, make sure you have all of your poles. There will be 4 straight green ones, 4 straight blue, 4 straight burgundy with plastic feet, 4 curved yellow, 2 small orange arches, a straight pink and a straight white.

Before you start putting the poles together, stake the tent down at every loop point around the base of the tent. There should be 10 of them. Make sure they're fairly tight and the floor of the tent is taught and flat but not so tight that you tear the tent at the seam. Stake 1 corner first. Then put the second stake through the second loop in order and using a firm pressure, pull away from the first stake, along the line of the tent base, make taught and push the second stake into the ground. Repeat until finished.

The first pole assembly uses in this order, going out from the yellow arch, which is in the center. From one side of that arch, add one green, then a curved yellow, then another green and a burgundy at the bottom. Do the same from the other side of the center arch piece.

This arch outlines the door and goes through the 3 loops on the front of the tent, around the door, so the poles hold the tent up. the loops at the bottom are not for the poles. Every loop around the bottom are where the stakes go to hold it down. For now point the feet towards the back of the tent wherever they will stand on their own. You can fine tune it and firm it up once you get the second arch in place.

All green ones should now be used up.

For the second arch, do the same thing but use the blue instead of the green. So from the one side of the yellow arch, 1 blue, 1 curved yellow, one blue and one burgundy. Same order from the other side of the arch.

Now all the poles should be used up except for the straight pink one and the straight white one. These two go together to make a straight pole that goes through the metal loops attached to the yellow arch pieces and locks the two arch assemblies apart at the top.

Now this takes some maneuvering and some word smithery to describe but what you want to do is make sure the feet of the front arch assembly, are pointed towards the back of the tent and stop at the side. The back arch feet will point towards the front of the tent. They both stop about 6 inches BEFORE the center tie down loop on the SIDES of the tent, on either side of the center loop. The front arch will actually lean forward, with the feet pointed behind it and wedged into the ground, right up against the tent at the bottom, move it around until you have a nice firm feel to it. Same with the back arch but this one will lean away from the back of the tent and the feet pointed towards the front. Once you get the back arch into place, it will really firm up and won't budge.

Another way to describe it would be that the two arch assemblies feet will point towards each other at the side of the tent, about 6 inches before they reach the center loop on either side.

Hope this helped. =)

Green hazy upside down arch of color across the screen


Your convergence board is in need of reworking on a component level or replacing the board! And you will most undoubtedly need to resolder the vertical IC and all ICs mounted on heatsinks on the power supply board. This TV is showing its age. You may choose to repair and that may last a year more or so! Good Luck and thank you for asking!

Rainbow arch across the bottom quarter of the tv. the arch is green


possibly magnetic interference check and see if there are any magnets such as a speaker magnet near the bottom of the tv - if so move it away from the tv this should eliminate the arch. could be at the back or the front

Convergence. shadowing, arch top and bottom, red and green colors


You have a convergence problem. i see these set all the time at shop. first consult the article in tips and tricks section the fl231 fuse problem. it might provide some answer and might turn out to be a simple repair. If you do not have the convergence option under setup in customer menu then i say you have that problem.. otherwise it sounds like a convergence power board issue. if you have the options try autocovergence first and then if that fails try manual convergence of red and blue if the dont move then it will be convergence power board. let me know and ill try to talk you through it

Re Degaussing


Now Degaussing and convergence are two different things, if you say its degaussing then you should have just a color differential in a certain area, meaning the color should not be arched, everything that passes through should pass throu only with the changing of color. Now if its a convergence the the color may lift upward in an arch, likely separated from the other colors, Red, Blue,or Green. So now which do you think you have? Deguassing usually give you a highish green color or yellow

You have a failure in the convergence circuit. There's a circuit board ( the convergence board) which has 3 IC'c on it that drive yokes on each of the picture tubes red-green- blue. You probably lost power to these IC's or one or more may have opened up. Sometimes poor solder joints on these IC's will develop causing loss of convergence. Hope this gives you an idea as to where you problem is. Stargazer
