tc-40a420u blinking red

Can't Post

I have a TC-40A420U that doesn't power on. It powers on for few seconds, than it turns off and red light blinks continuously. I have the service manual, I checked the test points on the P-Board, 5.3 v and 24 v are fine but 16 V only at the power on, then the voltage drops. I also wanted to check A-Board, but couldn't find the test points on the board. There are 5 test points, but couldn't locate them. I am not sure where to check for failure, power supply or main or ?. any kind of help is appreciated. tks
