    SAMSUNG LNT5271FX still shakes after replacing Power Supply Board

    hey guys, long time!

    i replaced the Power Supply Board as it had a few bulging caps


    tried to replace Main Board next but replacement was a dud


    whats weird is the picture will shake but if i tilt it back and forth or after about 20 mins. it goes away, any ideas what i should replace next?

    thanks in advance for any help

      is it something i could solve by replacing a Board rather than taking the whole thing apart?

      thanks for your help

        maybe budm will have a idea what can cause the shaking but if you have a search on you tube regarding tab bond fix you will see whats involved this is only a guess that it maybe a tab bond fault hopefully a more experienced member will advise.

            hi budm! thanks for your help. it is doing what is in the .pdf

            i took the easy route and just got another TV, we needed an upgrade


            this Site has been super helpful so if anyone in Colorado...in Denver area wants it, you can have it for free

            i will also ship the parts i.e. Boards if you cover shipping


            i will list it here for one week, then post it in the Free Section on Craigslist and i'm sure someone could use it.


            the 2 main problems:

            it is doing the shaky picture in the corner but goes away and plays fine after 20-30 min.

            there is one vertical line less than 2mm wide on far right side, doesn't stick out too much like if it was something in the middle or a horizontal line

            other than that, hopefully someone can use it on here


            old Samsung model is the one in the front:
