That model has a safety feature built into it, and if the rear panel has ever been removed while the set is still plugged in even for a second it wipes out the HD circuits

Why my jvc television hd61z456 not showing in high definition


What is the signal source that you are watching on your HD61Z456?
The problem you describe usually happens when you aren't using an HD source or have downgraded the signal by the composite input on your TV. (Composite cables only support 480i SD signals.)

You will only see 720p HD content from HD sources, if you use HD compatible inputs. Some OTA channels are also broadcast as only analog signals (usually the -2 and higher sub-channels). If you have cable or satellite, make sure that you have the HD programming and have tuned to the HD version of the channel.

The HDMI and component inputs both support HD signals.

I hope this helps. If you are watching an HD source and the problem persists, I recommend trying new video cables. Next, check if you are getting interference from your devices by using a cable with a Ferrite core. See http://www.monoprice.com/Category?c_id=102&cp_id=10240 for HDMI cables with Ferrite cores. The cores help block interference. If you have very long cable runs, check the behavior with shorter cables between the source and the TV.

Just connected our directv hd receiver to the tv via component cables, because we just bought a blue ray player and the only output for that is HDMI and since there is only 1 DVI input we had to change the...


You may be able the settings of your directTV box to stop frustrating you. If you help me identify the model you are using, I can research the proper menu choices you will need to choose to select the correct features. There are many different directTV set-top boxes available.

My own home theater setup did the same thing, and my solution was to use component cables from the PVR instead of HDMI cables. It is too bad your blu-ray doesn't allow for this configuration.

My work-around until I realized that using different interconnects fixed the problem, was to turn the TV off and then on again whenever switching from HD to non-HD sources. This fixed my problem, maybe it will fix yours.

I hope that helps.

I purchased a SANYO-DP46848 42"HDTV. I have a Cable box and my cable provider (Time Warner Cable) provides free HD Channels. However.... I CANNOT PICKUP ANY HD CHANNELS ON THE NEW TV. WHY???...


I just got the same exact one, when it searches automatically the first time it doesn't look for digital channels. go to Menu>manual channel search>cable. it will look for all possible signals and will take forever probably. the free digital channels will take several seconds to switch channel to channel, but they're there! They will show up on your screen as "DC 91-2" or similar. you can switch back to regular cable channels with the input button, you just cycle through all the inputs. hope that helps.

Mitsubishi VS-60805 Rear Projection won't operate in HD mode with Cable Box


Since this is an older first generation (1999) HD TV it may not be compatible with newer HDTV receivers because the standards back then were different - Make sure the HD cable box is plugged into the HD component inputs on the back of the TV (not the DVD inputs) and that the menu setting on the TV is set to DTV (not RGB) video. This TV will only accept 480i and 480p signals on the DVD input. Also the HDTV input will only accept 480i,480p and 1080i (it will not work with a 720p signal,make sure your cable box is not set to that mode)
