My 47 in. Apex HDTV only a year and a half old stopped working. TV Tech came out and showed me a burned out board. I'm not sure what the board does. Can the TV be repaired or is it a total loss?

Why not get a repair/replace estimate from the TV tech?

This answer is generic:

Most of the time they use fuse resistors. Sometime there a number of them. They are not all the same. This is not a simple fuse. It is a resistor combined with a fuse. You would need the service manual to properly identify the fuse resistor and have its spec. You would then have to order the correct one from a parts distributor. If it cannot be replaced generically, the original would have to be ordered from the manufacture.

In any case, if there is a blown fuse on a power supply board you can be sure that there are failed components that are most likely shorted. This would mean that the board would have to be troubleshooted to find and replace the defective parts.

Most of the circuit areas and the boards in these sets are not supported to be serviced at the component level. They change the defective boards as in the same process as servicing computers.

As for the heat problem, if you can find someone who is technically very competent, maybe he can custom install a fan for the area that is getting heated. It should be possible to find a 12 volt source from the main power supply to run a small fan to assist for extra cooling.

If you have your set in a cabinet, or if it is wall mounted it may run hotter. We found that sets that are wall mounted tend to fail more often because the heat can reflect off of the wall back in to the set. Cabinets tend to not allow the heat to dissipate as well as out in the open.

SOURCE: Crackling noise

I think I have solved the problem. I dusted the tv completely. Then took the cable box and with a hair dryer in the cool setting blew out the interior circuits to try to remove all dust. Turned the set on no more crackling. Thanks for the posting.

SOURCE: vizio HDTV totally not workinig

It sounds like a problem with the power supply. I had the same thing happen on a TV that was only a couple of years old. It did the same thing that you have mentioned. Once in a great while, it would turn on, and then we'd just leave it on because we didn't know when we would be able to get it to work again. The problem was, to buy a power supply for it we could get another TV. It just wasn't worth it.

Your flatscreen might be under warranty. I would look into that.

SOURCE: Vizio 47" Costco hdtv has red floating areas!

After posting this problem we did call Vizio. They sent out a repairman (had to wait over a week) who fixed it by: Replacing the LVDS cable and the main board. (Just like somebody on this blog wrote somewhere!) We also had just previously called our cable company who came out (also free) and checked our system only to find the cable running around the house to the tv needed replacing as it was sending zillions of errors. The red flowing problem (called "red pixilation") was due to the Vizio LVDS cable and main board being faulty from the factory.
Just want you out there in web land to know how to get your similar problem fixed!

Need to test/ check supplied volts on convergence out ICs on main board and if volts are OK, replace both ICs.
