Screen has unusable signal across it
Hi, Check the cable connections to and from the TV.
Change the channels to see if there are others that are out.
If you are not using any cable company then you will still need a set top box to unscramble the digital signal. Good luck.
SOURCE: unusable signal
it was a fuse in the digital board i took it to an rca repair shop and had it fixed has been working great since
SOURCE: I am having a problem with an RCA tv..unusable signal.
make sure that you have it set to the right input signal source and that your source is working properly. if so then yeah, you need to replace the fuzle modulator.
Thank you ryolkowski!!!! We just tried your solution and MAN it worked like a damn. We were all ready to make a trip to the city to get a new tv, an expense we just didn't need right now. You made our day. I can't thank you enough. jabo

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.
