Your problem sounds like someone got a magnet too close to the CRT. This can be removed with a degauss coil (which you probably do not have) or it will eventually go away if your built in degauss circuit is working. Everytime you turn on the set the circuit degausses the crt so colors can be displayed properly. If the circuit is not working you will need to have a tech repair it.

Sorry to tell you my friend, if you do not have the original remote, you cannot adjust the set with the on screen menu. See if a friend or someone you know has a sony tv set that you can borrow one from. Sony does make a universal inexpensive remote I saw at walmart once. That should work too. Good Luck Please dont forget to rate this thread.

I think that you will find the picture tube to be more expensive than a replacement TV, if it is still available (unlikely). That being said, it is also unlikely that the tube itself is the problem, The more common problem is the horizontal output transistor or the flyback transformer. Either part should still be available for a reasonable cost. Check with a local servicer for the part numbers and costs. These are common parts.

Hello, my TV was dropped (rolled forward) and experienced the same problem. The shadow mask has shifted. In general this shift should be localized to section of the screen (usually the top). I managed to fix the problem using an array of magnets. It took a few days to arrange the magnets to compensate for the shifted mask. I used 10 strong small circular magnets. The picture has normal color but has some nonlinear streching (barely noticable) near the top of the screen.
Hope that helps if you need more advise try me at email@example.com.
