I need your help L42WD22 unsuable signal

Question

You have posted this solution and I have the same problem

If the TV will play a HD input then the digital board can usually be repaired by replacing the fuse on the board. It's not a normal fuse and there is a updated part available so it won't go again. Any RCA authorized service center should be seeing many of these and should be able to take care of it.

I have opened the back cover of the tv and also opened the metal cover of the junction/connection box...don't know what it's called the one that has the shielded rf tuner.

Know I'd like to fix my own problem but the thing is that I don't know where the digital board is situated at and what fuse people are talking about.

I have some experence with electronics so I figure I can fix this myself with a little bit of help from generous people.

Thanks.
