Insignia/LG pdp42x4 wont power up

My Insignia/LG PDP42x40523 is about 10 years old. It quit the other day. I have a standby light, but when i turn it on, it immediately turns off. I have replaced the y sustain board and the power supply board. Anyone have an idea what i should try next? I'm thinking the y-buffer board, but want another opinion. Thanks for any help you can giv e me
