TV turning off after just a second being on. Happened after it tried to eat a VHS. Any idea why?

I'm trying to help out my neighbor. She has a little 15 inch TV in her kitchen. She has an antenna with a digital converter box hooked up to it. The TV has a built in VHS. This morning the VHS cassette she was using kept trying to suck back into the TV. She finally yanked it out really hard. She wants to know why that would happen and also now the TV turns of just after the picture warms up and turns on. Should she repair it or is it just done? Also if you have any knowledge of this, what's a fair price? She's afraid of being taken advantage of because she's elderly.

Thanks for your help!
