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.

In sony tv`s the 4 blink code(sony error codes)usually means that there is a vertical deflection problem.
It is often caused by a faulty vertical output i.c and/or related components. If you feel handy with a soldering iron let me know and i`ll help you with it.
Hope this help Merry Christmas
