Power Cycles On Off

I have a Magnavox Model 19MD358B/38 LCD TV and started turning off and on all by itself. I replaced the power supply board (Part 715T2906-2 ) and I am still having the same cycling problem until I unplug the power cord. When it first starts, it goes through the startup process and it displays the tv video for about a second or two. Then the tv turns off and keeps cycling on/off every few seconds as if the power button was being pressed. The power button lights up, the startup information shows on screen, the HDMI tv video shows on-screen for 1 or 2 seconds, then the tv shuts off and starts another on/off cycle. After the PSU board was replaced, the TV worked fine for about a day.Is this TV toast or is there a repair/replacement part that will/might solve this problem?Thank you in advance.
