Hi everyone!

I am a computer technician, but very new to TV CRT or LCD repairs.

I got several CRT TV's I got for free. I use them to play my older video game systems. All of the TV's I got have a blurry and "shaky" picture. I know there are some adjustments I can do by opening the TV case and turning the little knobs, wich I did, the picture got a little better, but it is still shaky. I have done a video of the problem wich you can see here:

I know these are old and probably not worth reparaing, but everytime I get a free TV, it always seems to have a problem with it.

The particular model shown in the video is a Toshiba TV21C30.

I really appreciate your help.

Thank you!

That's weird. Are you sure you're feeding that thing a clean signal with decent cables?

It's been a long time now since I've worked on a CRT tv.
Can you open the back and visually inspect the internals?
