Hi there. I'm sorry to hear about your TV.
You have lost your vertical deflection - a component or component in the TV has gone bad and will need to be fixed.
To be frank, a 1980s vintage 13" television, is not worth repair. The labor costs alone would far exceed the cost of a new one. You can probably find one of these for under $100.
I will be here if you have a follow up comment or question.
Thanks for your reply. You indicated that I could probably find "one of these" for under $100. Could you please be more specific? Another 30 year old TV? Or, a new 13" TV that's a bit on the old-fashioned side? All the TVs in the stores are so modern and complicated. I guess I'm in the market for something old/old fashioned, but where can I find such a TV?
Not many people make 'tube type' TVs any more. If I was looking for one, I would try Wal Mart but I don't see any on their web site.
They do have a 19" for $168. That's not too bad.
Before I say good-bye...can you advise me on the proper way to dispose of my beloved Sony Trinitron 13" TV?
There are recycling places that take TVs. Your local county government may be able to tell you where you can drop it off.
They will make sure that it is recycled correctly.
