Re: Vizio VOJ320F1A Dead - no amber light

Thanks for your quick response, budm. I appreciate all your help. I don't think it's worth spending a whole lot of time on it. I will either get a new main board or new tv. Thanks again.

Re: Vizio VOJ320F1A Dead - no amber light

BUDM or anyone else- I would like advice on how to proceed from here. I don't understand what could be causing the reading to ground to be low resistance for a second and then go to infinity. If you think it will be a tedious and lengthy process to track down the problem, then probably best to buy new board. If you believe it would be fairly straightforward, please provide guidance. Thanks.

Re: Vizio VOJ320F1A Dead - no amber light

Thanks for the quick response budm. I managed to find some PICO II fuses and managed to solder one to the board, with high hopes. Unfortunately I guess I was way too optimistic. That fuse also burned out. I went back to test the output side of the fuse as you suggested and found it does have a reading to ground of less than 100 ohms. I did not see it before because it only lasts a second or two and then reads infinity. I don't have any idea what would cause that. Maybe I should just get a new board or new tv.

My tv went dead the other night while my wife was watching it. Just died! I took it apart and thought it must be the power board fuse. No - it was OK. Took readings at the 5 12 and 24 volt outputs. Only got a 5.18 volt reading - no 12v no 24v. Figured it must be bad board - I couldn't visually see anything wrong. But before I ordered a new power board I came across this forum and realized it must not be getting a "power on" from the main board (thanks guys for saving me from that expense). I then traced the wire(s) to the main board from the power 5v and discovered that the little surface...

Re: New Members - please post your introductions here

I need help with my Vizio tv. I know a little about electronics, but not much.
