Question for the problem with this VCR!

The VCR is not turn on iven pushinng several times on switch.

On the front display there is no light , BUT when I'm dissconnecting the 220VAC power cable and connect it again I see the VCR turned on for 3 second, and on front display "TIMER" is on and some more characters, and

the VCR is turned off.

2 times when I opened the VCR to fix the problem ,I released the front panel, and released the mechanical casset unit , the VCR is OK, but for 1 day, and the the problen returned again.

Thanks for who can help!
