I'm a working college student and have no money to buy a new TV. The one I have is a very old Sanyo (model #D525030, chassis #25030-00). When you first turn it on, it's fine, but after about half an hour the picture begins to scroll rapidly until it scrolls itself right into a small line in the middle of the screen.
I was told it was a vertical hold problem and opened up the back (after leaving it unplugged for 2 days) to see if maybe I could fix it easily, but neither my dad nor I could figure anything out. We adjusted every knob we could to see what it did; we ended up making the picture very dark and turning people red, but we could do nothing to fix the inevitable thin-red-line syndrome.
Does anyone know how I could adjust the vertical hold on my own so that I don't have to spend book money repairing my TV?
Thank you.
