SOURCE: Can't View Cable RCA f32444

You will have to go in the menu and switch it to cable mode, then do an autoprogram and you will have all the channels.

SOURCE: I have an RCA converter box hooked up to an RCA tv

Basically, you cannot use the coax connections for both the VCR and the RCA converter box. I would hook up the phono/cinch connectors from the VCR to the TV if you can (these are also called RCA connectors, but I'm avoiding using that name so we dont confuse the digital receiver with a cable/connector name that is the same here). There should be a yellow one for video and red/white ones for left and right stereo. I believe the RCA converter comes with a three headed cable that can do this for you. With this configuration, you can set the TV to input on these connectors and the VCR should always output there. Once that is set, you can still use the converter box to receive the signal from your antenna, then run the coax to the VCR. Now, the VCR will always have to be set on channel 4 in your setup and you will need to manually change channels on the converter box for it to record a show. Does this make sense so far?

SOURCE: my rca tv 20f424t doesn.'t show thw correct

That is the Digital range of channels, since it is digital you will not need a converter box for this model. Their is also an Analog range of channels which is the primary setting, You will need the factory remote to switch from Analog to Digital... Without that remote you might have a problem their isnt a way to switch within the menu settings, good luck!!!

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Rca 46la45rq has backlight and power but no sound or picture replaced main and inverter boards


Was this the original problem before replacing the main board?
Maybe you have to set the new main board from maintenance menu. Sound and image comes from the main board, so i believe it has to be something about it...

good luck

46 rca model 46la45rq comes on for just a second then the screen goes black and it only plays sound! what needs to be replaced


Sounds like you have a backlight problem. To verify this, turn on the set and dim the lights in the room. Take a bright flashlight and shine it on the screen. Do you see a faint picture?
