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.
