SOURCE: 42 inch rca lcd tv says unusable signal

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.

How do I reset the password on 42 inch panasonic t.v. ?


It can be reset by turning the tv on and while pressing the "volume down button on the main unit, press the menu button on the remote control for more than 3 seconds. The self-check menu appears on the screen. Then, disconnect the ac cord from the wall outlet. You will back to when you first bought the set.

I have a 42 inch lg tv the volume just started going up to 100 or you can turn it back to 0 by it self why?


Volume controls are these days operated by an IC. If these go faulty all control is lost. It's not a job that can be done yourself as these IC are mostly flat surface mounted types with lots of pins to unsolder.

I have a 42 inch sharp aquos and the volume doesnt work on the tv or satellite remote, what is the problem


Let verify first to narrow down to where the problem can be. First, check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.
