RCA l46wd22 tv gets sound through surround sound but not from actull tv speakers how do I get to the sap

SOURCE: No Sound on RCA L46WD22

I own the L46WD22 for a few months and lost the sound and analog inputs, only HDMI worked, apparently this is a design flaw and they should have recalled all units. I didn't really needed the speakers because I have a sony receiver where I playback the sounds, but I decided to repair it myself after I neglected to take it out to the repair center and use the warranty. If you have a little soldering experience you can fix it, or you can buy the fuse and take it to any repair center, the problem is a surface mounted fuse that is located in the PCBA where all the signal inputs are, the component location is 1C33 the fuse has the letter F printed on it, you can't miss it, it's about 2 inches behind the tuner where you plug the coaxial cable. the fuse I bought it's marked with a G letter, it's 750mA, I just soldered it on top of the one it has, now I can hear the speaker and use the analog inputs (and now I'm the hero and have a very happy wife). the whole fix took me about two hours

This is a very common problem with these models.
The problem is a fuse that has blown, if the following is true:
No Video on any input BUT HDMI and
No Audio at all.
Purchase a fuse, these are freaking tiny from digitalkey.com or mouser.com F1455ct-nd
Pull the back off of your unit
Pull the cover off of the PCB housing. It is the box that contains the hook ups including the cable tuner.
The silver box that you screw the cable to is where you begin to look for this fuse.
About two inches behind this silver box is some numbers printed on the board 7c32 and partially obscured will be 1c33
Using a big magnifier look next to the numbers listed above, you should see a tiny rectangle fuse with an F on it.
This F fuse is a 500ma fuse that is too small for the load
The fuse listed above will have a G on it. It is a 750ma fuse.
Call the repair shops in your area, tell them that you know the problem, have the part and you want to know how much the bench time and labor will be to repair your unit.
