Toshiba 37av500u screen flickering

[woodman45]

Hello as the title says I have a Toshiba 37av500u where the screen is flickering and what I mean is the screen lights up dimly and goes off in a one second interval and continuous until you unplug the power cord.
The power button will not stop the flickering or blinking whatever you want to call it.i took the back panel off and did a visual inspection no bulging or blown caps.also can see the backlight going on and off.
I have not checked anything yet with the multi meter,I have searched and seen maybe the master or slave inverter may cause this issue but figured I would ask for help here before proceeding on any testing.

Is there anywhere I can start testing.

Re: Toshiba 37av500u screen flickering

Where do I check for the 24v?
I'm a beginner I know how to use multi meter and test caps but I don't know exactly which board to start test.
I thank you for any assistance and do want to learn instead of throwing parts at it.

Re: Toshiba 37av500u screen flickering

Just to update I took a close look at power supply and tested all the 24v 12v & 5v pins on the board.the readings were very close or right on the money.such as all the 24v readings were 23.96 & 5v pins were 5.03 on my meter.
So would it be safe to assume the problems lies within the master or slave inverter boards?
If so is there any way to test them?
Thanks for any help or suggestions as I would greatly appreciate them.
I will include a couple pics of the power supply.

I resoldered all the transformers on the inverters and it's still doing the same.

I replaced the master and slave inverters and still the same problem.does anyone have any suggestions or a service manual?
Im wondering if it could be a problem with power supply board?
