    I appreciate that everyone doesn't speak or write English as their native language.

    If this is the case, you will have to write a better description of what is happening. It is clear you understand how to use a multimeter and know about electronics. We can help, but we just need a more clear description.

      Please explain 'hit'.

      'tek tek tek' sounds like a SMPS that can't start. The usual cause is a shorted horizontal output transistor.

        "hit" i mean hight voltage from line .
        olso the horizontal transistor is good.
