    Vizio VX42L white flash on power up then nothing

    So I've dabbled a very little bit in repairing lcd tvs first of all. I got this tv for free knowing it did not work. I removed all the screws from the back cover but it will not come off! Is there a trick I'm missing here? I know the problem is most likely some caps on the inverter boards I just can't get the dang back panel off! Lol someone know a trick please help! Thanks

    Screws hidden behind labels, catches, clips, etc all come to mind.

    I don't recommend trying this.

      I got the back off. The caps on the master and slave inverter boards look swollen to me. How do I post pics of them I've never seen swollen caps so I don't exactly know what they look like.

        Use the "Manage Attachments" button when replying. There are restrictions on image size, so make sure they are under 2MB and the longest side is no larger than 2000 pixels. Use macro mode on your camera if at all possible as well.

          Look at the first two links in the signature of post #2 above.

            i see a recap in the near future... sounds like a recap might make it run. if so, you gust got a flatscreen for the cost of caps and some time soldering.

            can you see what brand the caps are? if there are non-swollen ones of the bloated brand, replace them too, they could fail just as easily... or they could have failed without bulging. any other non-swollen caps--> report brand here, they might also be suspect.

            and yes, pictures are always helpful.
