    Panasonic TC-P50U50 Will Not Power On

    So directly after a move to a new house my TV seems to have stopped powering on.

    I pulled the back panel and checked connections between the boards and found one slightly loose connection. I buttoned her back up and tried to fire it up.

    When I plug the cord into the wall I hear a faint relay click, but pressing the remote button or power button on the TV does nothing.

    When I count the red blinks on the status LED I get (14?) blinks.

    I have downloaded the troubleshooting guide for the nearest model I could find online. 2012 Plastma FHD TV-ST Series guide and it gives me a translation as to what blink codes indicate what.

    The table indicates blink codes from 1-13. Apparently I am either mis counting or this guide doesn't apply to my p50u50.

    Please lend a hand in guiding me in the right direction to solve this problem. I know just enough about electronics to be hazardous to whatever I touch.

    Thanks in advance for help!

        Yep, saw that video. Unsure if it would apply to my P50U50 though....

          Do not follow that video. It is flawed . I had posted comments to that effect but good ol SJ has removed them. just have a good read of the long list of people who have wasted time and money replacing both.

          I have little respect for SJ anymore they are rude and arrogant,

          I don't know about your issue but shorted Vsus is a very common cause for the 14 blinks in that model.

            Well, is there a way to identify what component is bad?

            I don't really like throwing parts at a problem and would love to troubleshoot the parts and identify the culprit.

            Any p50u50 resources I should look at for this 14 blink code?

              I can't find a reference for 14 blinks for this but does not mean it can't produce one. I think if it was me I'd try checking out the Vsus lines for short maybe on the SS board at SS11 and the SC. I think this is the series that blows SS boards and dead shorts Vsus.

              See what you find.
