Westinghouse TX-47f430S Will not power on. LED power indicator flashes blue then to red. Found some fluctuating voltage in the PS and replaced a ceramic cap and it cleared up part of that issue, but it will still not even try to power up. Even a link as to where I might be able to find a service manual would be appreciated.

Its either the main or power board, check and see if you have a voltage change on the PSON pin when you turn the set on, if you don't then chances are its the main if there isn't a change I'd try the PS...good luck!!

are you using an hdmi cable or the red blue and green cables that came with the xbox? if using the original cables there is a switch on them that sets it to HD or standard. hope that helps
