Samsung le32c450 TV wont turn on

Hi, my samsung TV wont work. When I plug it in to power supply red standy light turns up. There is no voltage output on supply board pins connected to main board (neather 5V stand by. All of them are 0V). Then I press the power up button and red stand by light blinks for several times and nothing happens. No image, no sound, nothing. However now I'm getting voltage from those pins and are according to specifications. Some say you should always get 5V stand by even if TV is just plugged in and off. Which is false in my case but after pressing power on button output voltages are fine. This gets me in doubts whether supply board is an issue or main board. Any help?

It sounds like folk are guessing.

At a TV tech/repair person you stop guessing and go buy the service manual so you can start the repair.

Service manual

Hi, tnx for answer. I did check the service manual according to symptom diagram and it just says change the main assembly. This could be multiple things but i would like to narrow down to specific thing.

Remember I take it you are a TV repair tech.

All the techs I know would have changed it, buttoned it up if fixed and if not, told the customer it is BER (beyond economical repair.) 32 inch sets are too cheap here so a main board replacement is never done anymore.

PS. There are exceptions where they change the mainboard. Example? Warranty work.
