Just removed rear panel to inspect boards. Nothing out of order. No bulges on any capacitors.
Expert:  Anthony_Infotech replied 7 months ago.

Regrettably you do have a problem here very likely to be the main-board this board is a data board and can't be checked , the fact that you are getting a power-light but its not booting in most cases indicates main-board failure do you think you can replace this board yourself?I will provide all the support and on-going support you need for this, let me know ,just to emphasize its a plug in board

It look like only 6 screws on ctr board. I think so. What kind of cost for board?
Customer: replied 7 months ago.
Also, how would I know if the other board isn't gone or the screen for that matter?
Customer: replied 7 months ago.
Anthony, are you there?
Expert:  Anthony_Infotech replied 7 months ago.

In most cases its the main-board there is no blink code procedure to help with diagnosis the set is not booting we would replace the main-board for this issue (out of experience)

Expert:  Anthony_Infotech replied 7 months ago.

Just give me a mo

Expert:  Anthony_Infotech replied 7 months ago.

You need to get the back off the set, locate the mainboard thats the one with all the AV connectors on, unplug and unscrew the board from the chassis, remove the board ,carefully examine the board for its part number usually found on a sticky label on the board or etched on the board, (you may need to go through a few codes before you find the right number)when you get the partnumber try www.shopjimmy.com first, if they don't have it google the part-number to locate a supplier, its the reverse to fit plug in and switch on TV (plug and play)
