Re: Protron PLTV-32c won't power on

I am also seeking help troubleshooting the same power supply symptoms on my Protron PLTV-32C. When I turn on TV 120vac power switch, the Power Supply produces 5vdc, and Main Board provides 3vdc signal to the Power Supply Board but for only about 7 seconds and then goes to 0vdc at which point the Power Supply 24vdc and the 16vdc have both ramped down to 0vdc. The Power Supply 5vdc is always present. Based on information in prior reply's, I replaced the Main Board, but still have voltage 24vdc and 16vdc ramp down symptom I have described. The Power supply does not have any obvious bloated capacitors, produces 5vdc all the time, and produces 24vdc and 16vdc during the 7 second 3vdc signal received from Main Board. Please advise on which circuit board(s) I should be troubleshooting and DMM test points. I will gladly send pics if I am able to post as a newbie (this is my first post). Thanks.
