Yes, see attached photos, the model indicated uses two of the STK-392-110 CHIPS FOR THIS--UPGRADE WOULD BE TO GO TO 150 CHIP.

TOTAL PARTS COST ON EBAY WOULD BE UNDER 25 DOLLARS (I KNOW A SELLER I USE) The only other thing that fails is this set has a number of 1.8 ohm resistors around them--one may be bad--easy to test.

The hard part in this model is getting at the parts, but I can tell you how.

If the photos and what I have told you told you something you did not know, rate this solution as very helpful as I do this here for free.

    Just getting back, but how do I go about getting at the parts. I've gotten the convergence chips. Is there a site where I can get a sevice manual (free).

    The best way to do this is with the back off and the set unplugged. What you need to do is free the entire chassis--you will have to disconnect at least 3 or more plugs-make sure you mark them.

    The idea is to get the entire chassis up so the bottom of the boards is facing the rear of the set.

    The chips are easy to find and will have 18 pins each, soldering is most important here. Here each chip is mounted on a large piece of metal with four pins that hold the heat sink and the chips in. What makes this difficult is you need to remove the chips (solder removed from all pins) and the heat sinks as a single unit.

    Make sure all the pins on the new chips are perfectly straight. Apply heat sink grease to the new chips and attach them to the heat sinks. You have to get all 18 pins on each and the four pins on the heat sinks in perfectly. Do the one forward first and the other after it.

    Two other things are involved. With both chips out you need a meter to check all the protect resistors around them, most of course are 1.5 or 1.8 ohm, should read like a fuse. They will not be burnt or discolored, they have to be tested.

    If questions about this I can help.

    Presuming you find all are good. You install the heat sinks with the chips back in one at a time and solder them back. Be careful you solder every pin and not short across them. I am also available if needed for real time help on Yahoo IM, if you want to do this let me know.

    Faster there than here.

    I am available to help.

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. =)
