Will not receive hd programming

Check the TV first by tuning it to an external RF source; ie; on-air program by connecting it to external Ariel and make sure that the TV is OK. If the TV works fine with on-air program, the Dish Network receiver is either fault, of it do not get input signal.

More information would be helpful. Check the screen settings on the TV. In addition, when my Dish receiver was set up the tech did not set the receiver to 16:9. This resulted in the HD programs taking on a letterbox effect with black bars on top and bottom. Compare picture from different sources (i.e. over air versus cable or sat receiver to determine if problem is with TV set up or receiver set up). If problem with receiver, verify output is set to 16:9 and not 4:3.

Well, first the 100Hz issue. Your TV will display a descriptor or the signal it is receiving, not a descriptor of the picture you are watching. Your TV panel has a native resolution and frequency. In your case, that frequency is 100Hz. Everything, like it or not, must be converted to 100Hz for the TV to work. In your manual, you are simply adjusting setting which smooth the picture and make it flow better than it would at 50Hz. This feature is slight of hand and is probably working just fine. As for the picture fitting the screen; HD programs fill the screen of HD channels.... SD (Standard Definition) programs use black bars on each side when on HD channels. You can use any available wide or picture size feature your TV may have to stretch the picture. You may be unable to stretch the picture, due to restrictions (some TVs will not resize HD formats).

did u see any burnt marks,,,,,,,,,reply me

thank u,,,,,,,,

an hybrid is a mixer of two signals and have one output or opposite, so check your video cables and connecters

In order to receive HD signals, you will need an HD receiver from Dish Network. You can buy an HD antenna from pretty much any store that sells TV stuff (Target, Wal*Mart, BestBuy, etc) which will allow you to receive over the air HD signals. But in order to get your satellite channels in HD, you will need an HD receiver from Dish Network.

Hello SuziCanevaro,

This may have been the sound of electrolytic capacitors exploding. I would not suggest plugging the set back in until you can have it checked by a qualified TV technician. If you are skilled in Electronics and would like to work on this yourself, you will need:

The schematic diagram, a multimeter, a signal generator, an oscilloscope, and an isolation transformer.

I hope this helps,

Thank you,

Its the broadcasting company and there "new technology" Have had an over the air box to get local HD channels and lost my PBS station, turned out to be a new signal incompatibility. The same is with my HP-S4253. Must not have the latest SW to process the new signals

more info would be nice. If you're using optical, make sure its securely in both the tv and your vr-405 receiver. I have owned the vr-405 since 2000 and i just purchased a sony 32xbr6. HDMI into the TV, optical out to the receiver, it sounds amazing!

Try removing 1080i from your list of available video resolutions in the setup screen of the Plasma display. If you are using a HD satellite receiver, check the LEDs on the front and note if the device is slipping into 1080 mode when the probem occurs.
