Question about JVC AV-30W476 30" TV

1 Answer

Cannot get low channels - but can get high channels

When programming the TV I can bring in channels 48 and up but when I try to get channels 2 to 47 all I get is a blue screen. No picture or sound. Have tried adding the channels but it still doesn't work. Worked fine before turning it off and when I turned it on, it was like that. Is it something in the remote I hit by mistake? I've gone throught the menu and try and find something and nothing helps it.

    Had the remote checked out and it is fine. They said it could be in the tuner.
    Don't have it fixed yet, but am going to call a repair man.
    Thank you for your help.

First thing I'd try is disconnecting the AC power for about 30 seconds then plugging it back in and recheck the symptoms. You may also have corrupted data in the EEPROM (a memory chip that holds the channel frequencies and other information the set needs to operate) which would mean a trip to the repair shop. Otherwise, the tuner would be my last bet for this symptom, another shop repair. If the first choice didn't fix the problem and you have picture-in-picture capability with two tuners, you might want to switch the cable to the second tuner stub and switch in the menu to that tuner to see if that works around the problem. If you were using a cable box, of course that would be where the problem lied.

Sanyo tv ds25030 how to program chanals 48-96


Your TV must be set in cable mode for channels higher than 69, and your cable provider must allow those channels to be received without a cable box. Menu, Channels, switch air to cable, run auto scan. If it receiving those channels unencrypted, it will find those channels.

I tried auto programming my tv but I can't go past channel 69. All other tvs go up to at least 99. When I try to manually program 99, the remote will only input a 9.


There are only a possible 48 channels available in the UHF bands IV and V; 21 - 68. Some Continental TV's still use band III; 1 - 20
Are you sure you are not getting confused by programme numbers which can go up to 99 and AU etc.

Static on all cable channels


The tuner is questionable The problem lies inside the isolation box. Ask a repairman to open this isolation box and resolder the small board. There are two small resistors that need resoldered. This also has the rf connector on it. And you may have him resolder the tuner if this does not fix it. Have him inspect any and all grounds on the main board as well. Good Luck

There is a button under the bottom edge of the screen (with the controls) that has the options "Normal" and "CATV" - press this and it should solve your problem.

Tv only has select channels


If you have a good cable signal connected to the TV and it receives channel 50 nice and clear but all lower channels have nothing but snow, then the tuner is defective and needs to be replaced. This is quite an easy thing to correct. Sometimes resoldering all connections inside the tuner will bring it back to life, but in either case the set should be serviced by a qualified tech.

TV sound problem


Hi Mah, It sounds to me that the tuner in the TV has drifted off tune. Your problem may be solved if you can bring up on the screen the channel bar which goes from 22 to 69, then `scan for channels'. saving the good ones and passing over the poor ones. Also selecting the program number before you save each channel. I do not think anything is wrong with the sound circuit.
