I have a big screen TV and lately, but not all the time (but most of the time), the picture will surge. Like it will get big and then smaller and then bigger repeatedly. Its dizzying. I know its an old TV. Does this mean its just dying or is there some way to fix it? I thought maybe it did it when it got hot or had something to do with the sound, but it seems to be random. Any help would be greatly appreciated!
