Samsung HCL473W 1080i red shadow & words are curved at top/bottom
When watching a football game or something that has words at top and bottom of screen, the bars the words are in are curved and doubled with red. The picture also is...I don't know proper word for it...ghosty and distorted (sort of doubled). I took it to a local repair shop and they charged me and told me they fixed it. They didn't fix it at all. I am looking for some ideas on what's wrong and can we just order the part and do it ourselves. My husband repairs computers.

I believe you have convergence problem on your rear projector TV. It require to replace may be 2 IC output convergence or the convergence drive, after replace those component you need to readjust convergence which mean you move the RED GREEN BLUE to be 1 on top each other you must have the remote control and service manual to get into the service mode, if you thing you can get those part in your country the service manual I may help you with that, ask your husband if he like to challenge it. I hope that is give you some ideas

I have a BENQ MP622C and had the same problem with shadow on the right side. I found out that there are two screws for adjusting the position of the mirror. One on the top of the light tunnel and one from the side, when you look from the front, just next to the main lens, see pics below. It helped me a lot, maybe another 1000-2000 hours of play, hopefuly more....
my lamp problems usually start with red shades in bottom corners - red, black - same issue I think. check your hours of filter (and clean) - clean inside your housing as helps and check lamp hours - you usually get 1500 to 3000 hours (check your user guide for lamp hours) try and live with problem until you need new bulb as not cheap
You have something on the lens. If the lens was producing excessive heat it could be the melting around the lens itself, or it could be grease from your finger that was clear until it got hot enough to cook onto the glass. Either way, remove and clean the bulb lens (the one on the bulb you change out when the bulb blows) and then re-clean the focus lens on the front of the projector (the one you turn to focus).
If this doesn't clear it up, look for damage on the focus lens or the bulb lens.
The light tunnel inside the "engine" is either out of alignment or the glue holding the tunnel together is coming unglued and 1 of the 4 sides has fallen in. There are 2 screws to adjust this if the tunnel is still intact. One or both screws can be accessed by opening the lamp door and then you have to remove a thin sticky cover. You will see 2 small screws that will have to be adjusted with a small torx (3) or allen. You will have to have the safety switch pushed in with something and adjust while the projector is on, using the most easily accessible screw, turn it towards the direction of the "banding". It should decrease. If not, turn the screw the other way. The screw that is not so easy to get to is for adjusting the banding the can appear across the top or bottom of the screen. If the banding gets worse or even starts to show diagonally across the screen, it is a good bet that the tunnel has collasped.
