SOURCE: Unusable Signal
Hi. What you need to do is plug in a cable or Antena in its place, and reprogram the channels. if you did that, then try to use a VCR or DVD player and install it using the RCA cables. Install the cable to the DVD or the VCR. If nothing works, My TV has a crack in the LCD. I'll either sell it to you, or buy yours. Let me know. Thanks.... email me to [email protected]
Thank You...

OK...1st of all I want to GREATLY tetraedronic, who wrote to replace the F fuse with the G fuse. I noticed our TV had the exact same thing go wrong. I searched for the item # F1455CT-ND and bought it from www.digikey.com for a whole $2.85 including shipping. It arrived in about 2-3 days. Hubby bought a fine SILVER SOLDER and a $20 solder gun @ HomeDepot. We placed a quilt on the kitchen table, turned the TV on it's face and took off the base & back and them the back panel on the metal casement. About 2 inches behine where the coax plugs in there is a TEENY TINY fuse with an F on it.....we placed the new G fuse right on top of it and with the use of a magnifying glass we barely touched both ends with the solder and reassembled all we'd disassembled. Hooked Coax and power back up and BADDA BOOM....we have sound and the analog channels back. For us, there was NO other option. NO ONE here in SE KS will touch this TV. Oh, and when I say this fuse is small.....well...be prepared....you may inhale it, it is SO dern small. I bet it would take 4 or more of them to cover the head of a match from a matchbook...NO LIE. E-mail me with any questions if ya need. [email protected]
Once again, THANKS A MILLLLLLLION for this fix idea!!
Stacy, Johnny, the kids and the dog :O)

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.

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.

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.
