P100 on TV screen, no picture

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.

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!

Maybe there is a setting that should be SAVED.

Hello a s ramsay,
What is the model of your plasma tv? Because if it is new, there is a scroll bar in your tv that can wash away that p100. You just have to go through the settings. If it is an older model like last year, then you can try going to a static mode. When I mean by that is when there is no picture but just a scramble. Leave it on for a few hours and hopefully it should it take care of it. Good luck.

Hiya Margy,
I know your query was 6 months ago,but I had a similar problem with connecting an Aiko SD set top box to our second older tv set & after 3 months only recently found the solution!
Our problem? When connected the tv picture went green! Nobody,including Tandy staff,knew what to do! (We also have an Aiko STB connected to our newer tv and it worked fine from day one.)
Anyway,it took 3 months but I finally worked it out.
Our problem was settings on the TV,NOT the STB.
Go to your TV's COLOR settings,pick a setting called 'COLOR SYSTEM' and change from 'ntsc' or 'pal'(depending on what country you're in) to AUTO.
It isn't enough to change the tv system on the STB's SETUP menu,or to change it on the TV's SYSTEM settings,you have to change it in the TV's COLOUR settings as well. Change colour system to 'auto' and see if that helps.(And of course,change all system settings on both the tv & the STB to AUTO or the right system for your country if you haven't done so) Hope this helps! Good luck!

Blue screen means tv is not getting signal. Either stb is not working or you are not connected to it correctly; check the cabling.

While it is possible to damage a TV by feeding it a signal with incorrect sync settings, it is unusual these days.  It has probably reverted to a different display mode.  I would try to look in the manual or the menus for a "Factory Default Settings" option or similar.  Once you restore the factory settings, the picture should return to normal, although you may have to change some settings back to the way you had them before the reset.  Good Luck!

I called Verizon and exchanged my STB from a QIP 6416 to a QIP 7216 and it solved the HDMI audio problem. This looks like the fix.

would almost think that your hdmi cables are bad if all other inouts are correct try replacing your hdmi cables
