The only way to fix it is to reduce raster size if you can get the video image out of the affected area - Possible with FP, not possible I don't think with RP...
The cost depends on the brand of the unit, coupled with the price of second-hand parts - plus tech-time to swap 'em out... Basically expensive, especially if you want new tubes...
If you read the manufacturers warrenty / user guide they almost always have a section in there warning you not to use the unit for computers, video games etc - and that it is not covered by warrenty unless under extreme circumstances.
I don't watch much TV - but I curse like the devil when I see a station logo in the corner of the screen that is not transparent, I won't watch those channels and remove the from my subscription if I can - not a major problem though as I think I have racked up less than 20 hours of TV this year - the flip side of that is I have racked up over 400 hours of movie watching But they don't hurt my PJ they make it happy
There is no possible way to get the image out of the affected area. The affected area is the area that has been used! You can reduce the raster area (possibly) to vied ONLY within the burned area. This will not change the fact that your color purity and greyscale have left and will not return.
I know of no manufacturer who will replace burned CRTs gratis. It is generally considered to fall under misuse and abuse. Good luck.
It should be noted that CRT burn in is not covered by any manufacturers warranty. It is not covered because it is caused by pushing the projector beyond its recommended range of use. You are free to run a projector too hard, but its not free to fix it afterward. If you want a brighter image, get a brighter projector and a blacker room and a brighter screen. Don't run your projector too hard and you won't have to worry about wrecking it. You will know, without a doublt if you are running it too hard. Use Avia or VE and check out the blooming boxes. If you have ANY blooming, you are running it too hard. If you can't get a bright enough image without blooming, you should change other, cheaper things to achieve a brighter image(black room, bright screen, smaller screen, brighter projector). Just my 2 cents(with the exchange, I owe you money!).
