Garage door does not hold when open manually

when power lost, I try to open my garage door manaully. I pull red string and lift the garage door easily. I pull door till the end (full open) and release the handy. the door was not held there, instead came down and closed again. What is wrong with it?

Sounds like the door is not balanced and the springs need to be adjusted.

when power comes back, I can hold it at any location by press electic button. The spring looks heavy, how can I adjust? Loose two srews, and rotate seat clockwise a little?

If you have a torsion spring (the kind that wraps around an axle running above the door opening) it stores a tremendous amount of energy and can be very dangerous to adjust. We don't recommend this as a DIY task because you can really hurt yourself if you don't have the proper tools and know exactly what to do and how to do it safely. Best to call a GD service company and ask them to adjust the spring tension.

I agree with Paul - tightening a torsion spring is a straight forward job but if anything goes wrong, the results can be catastrophic.

There are torsion springs.
