I had the unit set to a second zone that ran into a splitter for four different areas of my house. The second zone is not working, how do I test to see if it is the denon unit or the splitter ?

this all depends on the location of the thermostat that will only cool the area where it is at that tempature that you have it set on if you have a hotter room then you have to either turn it up to a higher setting cooler or make sure your ducts are open or insulate that room better it is to hot

In fringe areas; where signal strength is too weak, this should happen. It sounds that, you're using an Ariel booster along with a splitter. Just connect one TV at a time, without using the splitter. If picture break occurs even this time, adjust the the signal strength of the booster [either low or high], and check whether it can help you. Keep in mind, iv the signal strength is too low, or set to too high, this fault will happen, as AGC [automatic Gain Control] circuit inside the set won't function properly. Gopakumar Gopalan Google

have you got it set on second out put on the sky box as number one is just normal. all cables have to be set to second output using a splitter box . so its like this.
arial in booster.
out booster to sky box.
out to tv/etc on first output on sky box.
second out put to spliter linc. ( eg 4 rooms out four way splitter)
each room with sky eye fitted to end of the aerial from number feed from sky box.
with each room with Eye sky can be controlled
also check that RF outlet power supply is set on sky+ or HD in settings menu.
access this.
settings
select ( remote)
type 01 (select on remote)
RF outlets.
RF outlet Power Supply ON
RF channel 25 ( is best for most areas)

Try this to isolate where it is coming from. Either the zone amps are defective, which is not likely, or the main amp is at fault. Hard to believe they are mis-wired, they typically are foolproof in this area.

At the main controller, try the two zones that are good and plug them into the 4 bad zones one at a time and see if you get the same symptom. If you do, then it is not the main controller and something common to the 4 zones is causing the issue. If they are wireless, then you my have interference so check if you can select different channels.

Zoning, in the A/C world, refers to different areas of the house which may be cooled to different temperatures. Zoning is accomplished by closing/opening vents.
Zone 1, 2, 3 etc. do not have any particular meaning, except to indicate zone control flappers 1, 2, 3 etc. which are physically inside the ductwork which determines the zoned area.
Just because you have this fancy thermostat, does not mean that your house is actually zoned, but I am not to sure why such a thermostat would be purchased if it was not (unless it was free).
Zoning uses dampers. Is there air blowing out of the registers?
:o).

At your indoor unit, look at 1 of the front panels and see if there is a clear, plastic view port. Look through it and try to see a red flashing led. Count the flashes and look at the factory data on the front of the unit. That should give us a trouble code and lead us in the right direction. Also make sure air filters are clean.

To have good picture quality you need zero DB (decibels) for one TV without a splitter. You can use and inline amplifier for each individual TV hooked up to the cable input with a output leg connected to each TV. If your house in wired in parallel (one main input hooked up to a splitter with all of the other TV's run off of the splitter) you can use a whole house amplifier hooked up inline between the input line and the splitter. If you house is wired in series (the input goes to the first outlet, then splitter to second outlet and so forth) each splitter knocks your signal levels down 50% each splitter. Amplifier placement depends on how the home is wired and how many TV's are in the home. Splitters can be either balanced (50/50 split) or imbalanced (75/25) etc. On a two way splitter 75% of the signal goes out one leg, while 25% goes out the other (usually for FM transmissions). If you have a three way splitter the signal is divided by the number of output legs. Splitters do go bad as well (sometimes only one leg). You can also buy an amp that is multi- port (which splits the signal and amplifies in one unit/ one input and 2,3,4 outputs). Amplifiers are electric and there is no way that the splitter can interrupt the power that would take all the signal away. If you meant that it drops the signal level so the picture is unacceptable, that's different. If you have another splitter in the house try using that one, the other might be bad. All in all you can purchase most anything you need at a Radio Shack and are very inexpensive. Amps can be purchased in different gains (boost). +10db, etc. I cannot believe that your cable company is giving you such minimal signal that 1. you need an amp?, and 2. that one splitter drops your picture to nothing? Your line extenders (amps for the lines that feed your neighborhood) might have problems or need adjustment by the lazy, cheap, cable co. also. I had problems with my cable company (when I had one) my modem would not stay online. 4 months later, they diagnosed the problem and my drop (RG56 cable line that feeds my home from their tap in the cable box outside) was bad. My friend could stay online and 2 months later comcast adjusted their amps (line extenders) in the neighborhood and then he was fine. I know this is a lot to digest, but I'm just trying to draw a clear picture so you can understand it all. I hope this helps and good luck!

The 2 jacks on the back of the Arris modem are labeled "1/2" & "2". The first jack labeled "1/2" means that the jack is capable supporting 2 different phone numbers, a line 1 and a line 2. The second jack labeled "2" means that it is capable of supporting only a second phone number. Therefore your 1 phone number is working correctly from the port labeled "1/2".

There are different types of phone splitters. It is possible that the one you used may have been to split lines 1 & 2 on a single jack into two seperate jacks. Take a closer look at the splitter and see if the 2 ports are labeled differently.

Hope that helps.

it is not your hard drive
you have to reset the video setting and it will work again Hdmi is different on each tv so you have set this up again ok let's do this with the unit off turn the main switch on the back of the unit connect your Hdmi cable to your tv now place your finger on the front on/off switch keep your finger there ok now turn the mainswitch on the back of the unit the playstation turns on but don't remove your finget yet wait about 4 seconds or until your heard another bip (not the one when the playstation turns on) once you heard this bip remove your finger before the playstation turns off if you let it turn off try again all of this but if you remove your finger on time just wait few more seconds and bingo you have picture again using Hdmi
