Please note for this type of repair, ie no power and no led lights, until you actually replace the faulty power supply there is no telling what else could be wrong with the TV. Once you repair the power supply then you can investigate further depending on the numerous other symptoms that may appear.
Get the replacement board here from RGB TV PARTS:

Ebay and Ebid, i found the part on the latter from RGB TV Parts on www.ebit.net

Hi
I have a board for power supply board KDL-46w4500 1-876-467-21 A1557559A but one of the connector with 9 wire can not fit to 7 pins male sucket.
any suggestions
So I have a broken screen on a brand new Sony Bravia I've reached out to sony and other places they say that Sony doesn't make replacement screens.. I'm wondering what I should do now.. it's a super nice TV and I would hate to have to throw it away just because of the screen.. anybody have any advice??
How can I know that the power is on, instead of off when there are no indicator lights to know?
Hi, thank you for the great video!
Similar to you I have no DC voltage coming out of the PSU on my Sony 40S400A. However, in your video you mention that the replacement PSU needs to have a matching circuit board number (ie. 1-876-467-13). What about the part number (ie. A1568130A), does that need to match also for compatibility??
why didnt you check the fuse on the power supply board
How much did u spend for the power board? Thanks
Thank you for sharing your knowledge concerning power supply boards. My TV wasn't getting any power, so I went to Best Buy and bought another one. Just for the heck of it I did some diagnostic testing on the power supply board on the broken TV and found the main fuse was blown. I ordered a power supply board from ebay for $23.99 free shipping and installed it and the TV works great, and years of dust has been cleaned up. It all worked out great because we needed another nice Flat screen TV for are garage. People may say that the Sceptre TV's are junk, but it lasted me over 10 years running all the time. I suggest that if you have some technical knowledge and have a TV that is broke to try and do some troubleshooting using youtube to guide you as to what to look for and test, because you may just find the problem for penny on the dollars compared to taking it to a TV repair shop. Thanks again.
what did you repair? …………………………..replacement.bullshit
I have a sony bravia 2015 xbr 55x810c has no power at all ..i did the first check with the power cable and I'm getting 119v do you think it's the cable and what causes the cable to be like that?

hi there. i have a sony kdl-40v4000 purchased in 2007. The sound stopped working 2 days ago after turning the tv on. The only thing i did differen't before this error is using a chrome cast in the side hdmi slot. i have tried other means of sound including hdmi to external audio system and headphones but with no luck. i have tried a factory reset as per the options in the tv menu and have explored many settings. Have you any advice or ideas why this error of no sound has occurred? thanks in advance.
