SOURCE: rca 46 inch lcd tv, no sound
Go into the menu and change the HDMI Audio settings - the manual will give you a breakdown on this. HDMI is a little glitchy - if you were using red/gree/blue cables before switching to HDMI, you might want to consider going back to them - just an opinion.

The matrix drive board, or the screen itself most likely has failures. The fix is to change the board, or to replace the screen assembly.
On rare occasions it may be a bad connection with one of the ribbon cable assemblies that is not too complicated to service.
This type of repair may not be feasible. You will have to have an estimate done.

This is a very common problem with these models.
The problem is very likely 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.

Metric screws M5 or M6, you can get them for about 35 cents each at HD or LOWE, so you can get differrence sizes to try.
