I have a customer that has a Mits 62" DLP, Yamaha receiver, HD TIVO Directv receiver and DVD player with a 5.1 system.The problem I am having is a black line running vertically 1/3 of the way from the left of the picture. I the swapped out the TV twice already and he had the sat swapped out once. Same problem an all 3 sets. I have tried Monster power conditioners, Panamax, Richard Grey...... Nothing is fixing this problem.
I also have swapped out the video interconnects (AudioQuest YIQ-3) twice. According to the customer, it only happens on Directv and it is sporadic (once a week to 4 times a night). Sat LNB's have been re-ran. As well as a new dish and multi-switch. Mits tech support has thrown their hands in the air and said they don't have a clue. Anyone have any ideas?????

Have you tried running the directv to another input on the television or taking it out of hi-def and just running it composite (JUST TO CHECK) also when the line showed up was it on an hd program or regular satellite? had he just switched from hd to regular? How about changing the output of the satellite receiver try 1080i, 720p, 480p then 480i. I know i've seen a few tv's that just didn't like 720p (but were supposed to) but played fine with 1080i.

You don't say which Yamaha is being used, are you going component out from the DTV through the Yamaha to the TV? I would agree with the above post, try another input on the TV, bypass the Yamaha, also have the composite connected or even the coaxial. Next time this happens client is instructed to switch to other rate such as 1080i or 480p, if not fixed, change input or CH 03 on TV . If verticle bar is still there, he needs to confirm that nothing is happening in house. Did the air cond. just come on, someone making popcorn in the microwave, anything that happened or is happening at the same time. If nothing going on in house, then outside forces? Someone within a short distance have a Ham radio or other transmitting device? Does it do this on all channels from DTV? Because it only happens occasionally there are a number of things that need to be checked to try to narrow down the possibilities.

Go back to the beginning and post some details from your testing.

Is this happening on the TV with different sources??
(if no, issue is with souce, connection, or setting/config of source)

If yes, then on multiple inputs??
(if no, setting/config is wrong, or that portion of the input board is bad, call Mits service)

If yes, then with different settings??
(if no, then the issue IS in the TV, not the sources)

Anyway, go down the line and rule out the sources one at a time, the cables one at a time, etc.

look in the menu for something called raster setting or something like that. I had the same problem last year. you just need to adjust (move) the picture over. Its not the cables.

If it is the TV, start weeding out issues that the TV may have.

Check all outlets that EVERY piece of gear is connected to with a inspector quality tester.


Even if everything checks, get some thick grounded ext. cords and plug the set into another outlet on another circuit.
12/3 is good, 10/3 is better.

Put all sources on the same circuit if they are not already, even if this means running multiple heavy extension cable across the room.

10/3 directly from the panel's convenience outlet with all other breakers shut off would be the final test as far as power issues in the house...
(you may have to reset some clocks, but be sure to shut down your computers and DVRs first)

Disconnect all coax feeds, surge protectors, etc. and try a single source (plugged into the same cord) with audio and video feed only.

If it still happens, and that DVD player is OK on another TV in that house, your set is likely bad or you have something weird about your power delivery from the grid to your panel.

You will have to call the utlility company to get a clean bill on health on that one.

You just bypassed the wiring in the home, so something else is to blame.
You will need to do that test, because this is the #1 utility company excuse, "it's probably the wiring in your home..." NOPE, GET OUT HERE.

There was a guy that worked for us that had a Seleco HD-250 dual mode that freaked out at his place, and it worked fine anywhere else we took it. That specific processor in that specific projector on that specific AC service was the problem.

Re-reading it, I now agree with #574...

Certain channels have different amounts of overscan, and if the overscan is set too tight on your TV, it could be showing the edge of the image that would ordinarily be hidden in the overscan.

Oh well,
I am not editing the other posts, even though it's not useful here anymore, it's good to have posted.

The video inputs on the Yamaha are bypassed.The signal is ran direct utilizing the NetCommand feature of the TV. New info has came in from the customer. It seems that the last sat installer used the component video cables that come with the sat rec. He said the AudioQuest cables were junk. The customer has reinstalled these cables himself. So time will tell.
I never really thought about the microwave or HAM radios but I will look into it. On the power note, wouldn't the Richard Grey power conditioner stabilize this power influx??

Oh well, just a thought. I appriciate all of the info and I will do a test on the power circuit.
