We have switched the satellite physical input with the DVD input, to see if it was just the physical input, but the DVD player is fine on either HDMI 1 or 2; however, the satellite whether on HDMI 1 or HDMI 2 still shows these boxes. I also hooked the satellite to a video input to see if it would show the boxes and after six sporadic tries of turning the tv on through out the day, I didn't get the boxes. However, it seems that the symptoms take a while and then gradually get worse. When we first switched the satellite from HDMI 1 to HDMI 2, it took two days before we saw the boxes and now it is regular. (weird)
The boxes overlay the picture. The picture is in no way compromised, besides being overlain with boxes (like picture in picture, without the picture and being in middle of the screen). The boxes only appear when first turned on. They don't appear after 10 minutes or an hour of watching tv. They don't appear every time it is turned on, but does get worse as time goes on. Since we've been messing with it and not really using it (since it has been in the repair shop), the boxes were not showing that much, but now that it has been a week out of the repair shop, they show almost every time we turn on the tv.
We have also tried turning on the tv before turning on the satellite, but that doesn't work. The boxes still appear. however, it appears there is still a feed from the satellite even though it is turned off because there is a screen saver in the background flashing all over the screen behind the boxes.
In order to get the boxes off the screen, I have to select the "input" button on the remote control and the boxes line by line will disappear. That is the only way besides unplugging the tv or unplugging the satellite receiver from the tv, to get the boxes off the screen. Also, the "menu" or other buttons don't work when the boxes are on the screen, the only button that works is the "input" button. Once the boxes clear, the menu button does work, but the menu, or display may be garbled letters (doesn't do that 100% of the time).
The tv repair guy replaced the scaler, digital and controller boards since that is what they diagnosed when they came to our house. However, that hasn't solved the problem. He did see the problem.
Would the bad satellite receiver, LNB, cable, etc also contribute to the menu being all garbled?

Re: boxes on screen when first turned on
What is very interesting about digital video is that it works with memory, sampling, and clock cycles. If any parameter is off specs to the point where the correction routines cannot interpolate the data there will be errors shown. When these types of problems happen the effect can be unstable. There are many factors that can contribute to these errors.
What is also interesting with digital video, is that the error factors and characteristics can change with the content and with the change of content. When there is more than the average data to process, delays can be introduced.
I know exactly what you are talking about. I have seen aliasing many times with digital transmission and processing equipment.
If the processor boards in the TV set have been changed, logicaly this should normaly rule out any problems with the set. It would be a very big coincidence that the new boards have the same defects as the old ones.
If you can play your DVD's using the HDMI cable in to the same input where the sat was, and there was no visible fault, you know for sure that the fault is not with the TV set!
I would guess you even swapped HDMI cables around to rule these out as well?
If you have a set of A/V component cables, and your sat box and TV set has the component option, you can test the component input of your set from the sat box. This will still be able to be HD, but it will be analog between the box and the TV. This may point ot something later on if there is still a fault.
Many times over the years, I have seen intermittant faults with cable boxes and satellite systems. Anything is possible with these.
The simplist sat system has basicaly the following components:
Dish and LNB located outside.
A cable that runs in to the house that has CATV connectors on each end. The connector on the outside must be the waterproof type.
There will be two cable runs on some systems for a double LNB, or there can be 2 LNB's on a sophisticated system.
On the inside of the home, depending on the system there will be an A/B relay for the Horiz and Vert polarization for the signal being recieved. In a single wire system, this relay can be built in to the LNB.
Then there is the necessary cable feed with connectors to the TV sat docoder box.
If there is a shared system, then there will be a distribution system, and possibly multiple A/B relays, depending on the type of system.
What I am pointing out here, is that there are many parts of the sat system that can degrade the signal. I would start with the most simple, and that is trying a new box.
Ask your sat company or your dealer if they will give you a loan of a box to try.
Also, a professional sat system installer who has a spectrum analyser and knows what he is doing, can check out the system from end to end to see if there is any signal losses up to the decoder box. The next step is to try parts in order to locate any failures.
Here is another approach. If you have a neighbor or friend that is on the same sat service as you are, ask him if you guys can swap sat boxes for a few days just to see what happens. If he gets your problems, and you are okay with his sat box, this rules out the sat box totaly!
For your sat system, you can go to to the dish and make sure that the connector is screwed on securly. You can remove it to see if the center contact is okay, and also see if there is any sign of corrosion inside the conntector. Corrosion means water was leaking in.
You can follow through to make sure all the connections are okay. You will not be able to test anything without being able to substitute the parts, or have the equipment to take measurements.
Personaly, I am betting on a fault with the satellite system, and not the TV set!

Check the input jacks in the rear. Each should have a unique label. Pick one input that has cables connected to it. Note the input name. Follow the cables back to the device connected - DVD, BluRay, Cable / Satellite box, etc. Turn on the TV, and select the same input you noted above. Turn on the device connected to it (DVD, BluRay, Cable / Satellite box, etc.). If this fails, try again with a different device or connect the cable / satellite box to the antenna input and select ANT.
If you are unable to view video on your television set, the issue may be that the TV's video input selection does not match.
The TV input source must match how the equipment for example DVD is connected to the TV.
* Plug the RCA cables(red,yellow,white cord) to the designated ports. * Grab your Apex TV remote and attempt to cycle through the video inputs by hitting the "Input" button at the top of the remote multiple times. * If you have used a DVD player or similar external device recently, you may have neglected to switch the video input back to the one assigned to your TV programming. * Devices such as DVD players often reside on the AV 1 or AV 2 video input, and failure to switch back off of one of these will result in a dark, soundless screen when attempting to view cable or satellite television. * Cycle through the inputs until you land on your cable/satellite input once more, which should result in an immediate restoration of picture and sound. * If it does not, approach your Apex TV and look over the A/V cable connections. The A/V cable has two sets of prongs, one on either of its ends. Each prong is either red, yellow and white, and plugs into corresponding A/V ports on the back of the Apex TV and the back of your cable or satellite box. Make sure the ports and prongs are color-corresponding and have not been switched up.
Just fixed this myself - made my head hurt to figure out.
1. Switch to a setting (say DVD).
2. Watch the AVR screen as it switches. You'll see the audio and video settings. For example, Audio = DVD, Video = DVD
(Mine showed Audio = DVD, Video = DBS even though is was set correctly using the SETUP for audio and video)3. Under the round control knob on the left, push the (tiny) Video Select button.
4. Turn control know to choose the correct video source
Your system should work right. Mine did.
This model does not have a tuner so you will not be able to record off of tv unless you run your cable box or dish satellite's audio and video outputs through the dvd recorder's front or back inputs(L1 or L2) and record from those sources. Even then the cable box or satellite box would have to be tuned to the channel that you want to record. If you choose to do this you must go to your on screen menu and under setup/general settings/video/video input you will need to select the video input source(L1,rear or L2, front).
Most tv setups require that you change the input source to gain the ability to watch the proper peripheral e.g. if satellite is connected on video one and the dvd is connected to the tv on another input such as video 2.
If the satellite runs into the dvd unit and from there the dvd is connected to tv you may have to power off or on the dvd player to resolve conflict.
Another problem may be the resolution setting if your tv is Hi Def. Set the tv and receiver to the resolution e.g. 1080i.
You can also changed the way the satellite is connected to the tv possibly if you have other inputs.
Check the channel also, if the unit is connected with coax it would more than likely need to be on ch 3 or 4 if you are at the satellite receiver box location. If you are at a stand alone tv off of a dual tuner you may need to search the channels for the right source both air(analog) and cable(digital).
Hope this helps you out. If I can be of more assistance let me know.
sweetkiss, if it works through the dvd player and not on cable/satellite box then the tuner is bad, if you have any type of cable/satellite box try running A/V cables out of the box to video input on the back of the tv and switch the tv to that video input, ie; vid 1, vid 2 etc. (your using one of those inputs for the dvd) this will give you your picture back, you can of course also replace the tuner in the set, good luck, BMW Rider
I am assuming that you are using a surround sound system?If so on the back of the satellite receiver you will have RCA cables labled yellow ,red,white uuse an rca cable to run from the output on the back of the sat box to an rca input on the surround sound unit.the inputs should be labled on the back of the surround sound unit.once you have the sat box plugged in look for the output on the surround sound (rca cables) run one set of rca cables to the rca cable input of the Tv.on the original tv remote select the tv input that is the cable from the surround sound is plugged in to . make sure the surround sound unit input is selected to the input that the sat box is plugged into.this will give you surround sound from your satellite receiver,repeat with your DVD player plugging the DVD rca cable output to another empty input on the surround sound.to switch between the sat box (satellite TV) to DvD select another input on the surround sound unit.Try to correspond the units you are plugging into the surround sound to the correct name of the component on the back of the surround sound unit to avoid confussion.any questions,Im here to help.If this works rate me FIXYA! if it helps.GOOD LUCK!
Try looking on your tv's menu for "input" or "input select". This should allow you to switch to your front AV inputs. If that doesn't work hook into the coaxial cable in the back of the set (the one for your cable or satellite input. Plug the cable from the output or to tv side of your reciever into the input of the dvd player and run another lenghth of coaxial cable from the output of the dvd player to the coaxial input where your satellite or cable was plugged into the back of your set. When you want to watch a DVD just turn on the DVD player and the picture should come up. When you turn it off your satellite or cable should come right back.
