No picture or sound - think the tuner is bad

When the cable is connected directly to the TV or via the cable converter, no signal is received. Ichecked out cable line with another TV - all is good there. A TV repair show told me I could bypass the tuner and hook up via video connection but not sure how to do this. Also - if I use the video would this not eliminate the ability to use DVD player?

You may either have a bad tuner in your TV (not unusual for Sony's) or a broken connection near the tuner on the flimsy circuit boards they're using on this model. The tuner requires about 30 volts DC to work, and this may not be reaching the tuner due to a crack in the board connection. You probably have several A/V inputs that can be used for cable video and DVD video and your owners manual should explain how to connect them clearly. The outputs of those units go into the inputs of the TV set. It's That Simple!

TV quit picking up over the air channels while watching. TV Jack works on other TV and video cables in or HDMI connection works fine on the problem TV.

That is the part that contains the tuner.

No TV broadcast picture. Is this a tuner problem?

yes it does seem to be a tuner problem , I also wonder what happens when you use the auto channel finder and tuner usually found in the set up section of the menu ? As well as was your TV working before and receiving input via the antennae but has now stopped working in this regard ? I also noted that attaching an analog to digital converter box worked fine , so your TV is capable of receiving a signal via that method , dose the converter box use your antennae input jack or a video jack to send the converted signal into your TV ? if it is using your antennae jack then it may not be a tuner problem .

Denon 1312 receiver composite video inputs do not work.

I'm having the same problem with my Wii output. The manual for the Denon AVR-1312 says that analog video signals (i.e. component/composite outputs from the Wii) are not converted to digital video signals (i.e. HDMI output from the rcvr). I'm running only HDMI to a projector, so the video signal is essentially lost. The fix appears to be to run an additional composite cable all the way to the projector. Sounds like your fix is the same. No Wii tonight! :(

My tv got no sound..but if connect a video/dvd via rca ok.

Sounds like you have a tuner or an antenna problem. If you are using a DVT converter box to watch off the air TV, the signal has to be very good to get sound and picture. Try connecting a VCR or a DVD player trough the coax cable and see if it you get sound an pic on Channel 3 or 4. If you do, it is an antenna problem.

Can't record out from a digital input

It only passes the signal it see's. Digital for Digital and Analog for Analog. Try running a Standard analog RCA from your Cable box to the receiver then try and record. Hope this helps. If you still have an issue, post a comment and I can help you further.

I have a Hitachi 32CX38B, does it have a digital tuner?

To answer your direct question, yes it has a digital tuner. To answer your real question, NO it WILL NOT receive the new ATSC (digital) broadcast stations. The tuner itself is a digital one but works only for analog signals. The changeover in February will change the broadcast signals to a new digital format that will require a converter for your set to continue to function. Please note that the converter is only required if you receive your signal from rabbit ears or a rooftop antenna. If connected to cable or satelite, no change will be seen and no converter is needed.

No play back from HDTV to threater system

Do you have set-top-box or antenna-cable directly to TV?
You have connected TV with received via HDMI, but that won't work in this direction - TV has HDMI INput only, not output.
You can use HDMI to connect HDMI-out on DVD player for example to HDMI-in on receiver and HDMI-out of receiver to HDMI-in on TV.
But to get sound from TV to the receiver, use spdif optical or coax cable if TV supports that - this way you will get surround sound.
But also your connection via analog white/red RCA plugs should work, but only for stereo sound.

Hdtv converter box to vcr

Hi Drtrippy,

If I understand correctly, you are using your VCR for the actual tuning of the TV.

The converter box itself contains a tuner, so you should now receive extra channels available only to an HD tuner. You should try connecting your antenna as input to the converter box. Then output the signal from your converter box to the VCR. Your VCR may then remain connected to your projector.

You may simply think of this as if you are inserting the converter box between your antenna and your VCR, which should be currently connected to receive an over-the-air signal. Remember, as the tuner you will be using is in the converter box, you will need to change channels using the converter box, not the VCR.

Thank you,
Jason,
Go Ahead. Use Us.
