Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

That sounds very much like a short that is pulling down the power supply, esp. if the picture forms and shows on the screen for just a second, when powering the TV to On, before it goes black. Is that how it has behaved, even through the parts changes?

It doesn't do it every time the power button is pushed but keep pushing the power on button it may flicker instantly one time but at fist time powering on I can hear 4 low pops from speakers.
TV Technician: Russell H., Service Tech replied 1 year ago

Does the power light ever blink on and off? if so, count the number of blinks before it pauses and then repeats the blink pattern, please.

The green light stay on until it turned off also there is 24v to the inverter board and it stayes on until tv is turned off.

Do you have a service manual for this brand of TV?

It might cost a little -or it might be free, perhaps, if you're lucky - but it would save some money in boards swapped in that turn out not to fix the problem. It would contain troubleshooting information. Diagrams, part numbers, that sort of thing.

Would you like for me to seek a service manual source for this model line of Sanyo TV?

I am terribly sorry - other work appears to have distracted me from posting to this case again.

I must apologize.

Here is a service manual - to not go through it online page-by-page, use the green DOWNLOAD button at the upper left:

If I may provide further advice, let me know.
