Try a different HDMI cable. The one you have might be shorted internally.

SOURCE: mintex 37 inch wide screen. remote is working however cannot change channel, input source or volum. only turns tv off. The buttone on tv doesnot work connot change input source or volume

Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.

I have started setup for hd cable. Am connected to hdmi and have picture and sound but am unable to change channels. What do I need to do.


With the HDTV set for an HDMI Input that matches the HDMI Jack that you've connected to the cable HD STB (set-top-box or "converter"), use the cable STB remote to change channels on the STB - not the TV.

You can not change channels of the STB with your TV remote. You may however, be able to program your STB remote to operate your TV. Most will allow you to power the TV on / off; volume up / down / mute; change input (HDMI1 / HDMI2 / ANT / Composite / etc.) and even some of the more complex functions as well. Contact your cable company for more details.

Wont receive digital channels after scan non found


Hi Patrick,

You must have a UHF / VHF antenna connected to the antenna input of the TV to scan for digital channels. Most new TV's have a threaded, round 75 ohm coax cable connection for this - but yours might even have connection consisting of 2 small screws to connect a 300 ohm twin lead antenna cable instead. Use which ever yours has.

If you are using this input for the input of a cable TV "set top box" (STB), satellite STB, or similar, you will likely only find a single analog channel (Ch3 or Ch4) after a scan as the scan will only find the output of the STB - which is usually on Ch3 or Ch4 - and not be able to scan the STB channels.

Additionally, the antenna input of the TV will only provide a standard definition picture if connected via coax cable from the STB. It will only provide a high definition picture if connected to a UHF / VHF antenna and a broadcaster is close enough for its signal to be received by the antenna. The way to obtain the best possible picture (high definition) when using an STB for tuning channels is to use an HDMI cable between the STB and TV. An HDMI cable will provide the very best picture and audio signals from the STB to the TV; all over a single cable and is the recommended practice.

I hope this helps!

Trying to set up my new elements tv with a uverse wireless box. Did a channel scan but still can't find any channels. Help please!!


Is this a high def tv? Are you using an hdmi cable, component cable(red green & blue) or a low def coax cable to connect the tv? If coax, the tv needs to be on channel 3 or 4. If hdmi or component cable is used you need to change your input on the tv with your remote to the matching input you wired it to. The uverse stb (set top box) changes the actual channels once you have selected the correct input.

Connect with componet cables.


The only digital audio input for this TV will be via the HDMI input. Of course, even with HDMI in, you're only going to get a simple stereo output from the TV. You can use the analog L & R audio inputs for a very similar sound from the TV speakers.

The digital multi-channel audio (Dolby Digital, THX, 5.1, 7.1, etc) encoded in the program should be connected to a suitable multi-channel amplifier with either a TOSLINK (optical), RF (coaxial) or HDMI cable for theatre-like sound. This can be done by (a) cabling from the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) directly to a multi-channel amp and speakers, or (b) from the HDMI output of these devices (DVD, BluRay Disk, Set Top TV Tuner, etc.) into one or both of the TV's HDMI inputs. This will provide only stereo sound output from the TV speakers. You should connect the TV's TOSLINK optical "Digital Output" jack with an optical cable to the amplifier's TOSLINK optical input jack to obtain theatre sound.

To listen to the program shown, you would select the amplifier input assciated with the optical, RF or HDMI input that is connected to the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) if connected directly. If the TV HDMI input(s) are used, they are output to the TV optical output and should be connected to the amplifier optical input. The amp input associated with the optical input should be selected to hear the program with theatre-like sound.

Do you get video on any other inputs?? I think it is time to get the set serviced. I would suspect a problem with the y sustain or z sustain boards.

Two tvs off Motorola DCH3416


If you have different input options on your TVs, you could run the second TV with the Y, Pb,Pr component outputs along with the analog audio from the STB. However, remember the STB will only support ONE output video format. So both TV will have to be set to the same video format (720p, 1080i, 480p, etc)

Denon AVR-488 , problems routing cable box through receiver to tv


If you don't have one, the manual is available online: http://static.highspeedbackbone.net/pdf/AVR-488-OM-E_101.pdf

Suggestions:

1. Reset to default values. Per page 36 of manual: 1. Turn off Power. 2. Press Power while simultaneously pressing Speaker A and Speaker B. 3. Once the display starts flashing at intervals of about 1 second, release the two buttons.

2. Make sure you have AM or FM radio reception. This makes sure your speakers, amps, etc are connected and working correctly.

3. Connect DVD player to HDMI 1 in and TV to HDMI Monitor Out.
Play a known good DVD that works when you connected the DVD directly to the TV via HDMI.

Select the DVD/HDP input on the receiver and play the DVD. You should not have to perform any input assignments, etc. It should just work, as HDMI1 is the default system setting for DVD.

4. If possible, obtain a STB with HDMI out & repeat step 3 using the HDMI2 TV/CBL input. Keeping the signal path all digital (HDMI) will give you a better picture quality than forcing several analog to digital conversions (component video is analog).

4A. To use the component connection, first test by connecting the STB directly to the TV via component video/audio if possible. This tests that the component video output of the STB is working correctly.

Next, remove direct connection and connect via receiver. Connect STB to receiver as shown on page 13 in manual. Connect component video output from STB to component video input #2 (tv/cbl) on receiver. Connect the STB audio output to the corresponding tv/cbl audio inputs.

Make sure nothing is connected to the HDMI2 input or to any other TV/CBL inputs (composite video, s-video, digital coax audio).

Now select the TV/CBL input and turn on the STB. You should have both audio & video.

DENON AVR 888


hi dennon guy

you need to connect all your components to your receiver then from the receiver to the tv via the monitor out at the back of your receiver.

you need to make sure they are all the same type of cables. ie if you are using hdmi then make sure the dvd is hdmi output to hdmi input of the receiver then the receiver is hdmi output to the input of the tv. This will give you the best setup.

of course if u use component cables then the same principles applies.

good luck
