Default Strong Signal - Poor Pictures on all TV's

The most bizarre problem that I have ever encountered with television reception EVER!

I have a 2 year old fairly expensive Panasonic 55” plasma, a high end Samsung 40” LED that is about 3 ˝ years old, and very nice Samsung 32” LCD, which is now about 6 years old. All of these sets had impeccable picture, and especially the plasma. The plasma set’s picture was beyond impeccable. The LED picture was superior. The LCD picture was very good.

Tuesday AM - August 11, 2014

The color and depth perception in all three TV's in home became distorted “at the same time”.

Over the course of several hours I attempted to adjust the color and depth perception on all of the sets, but even those changes where not producing the quality of picture that were previously common.

Obviously it’s impossible for all 3 sets to have significant color and quality picture problems - at the same time - without some type of transmission equipment or cable connection failure.

I called DirecTV customer service.

After spending a lengthy amount of time on the phone with DirecTV going over settings on each of the three televisions sand receivers. I didn’t make any meaningful changes to the settings to any TV or receiver. Nor did any of the minor changes make any impact on the quality of the picture.

Following the call, I again attempted to restore color settings to all three sets. I still wasn’t able to get the color and picture quality as they had originally always been, but was able to make the pictures substantially better.

Hours later:

All three television set’s pictures once again reverted back to dull, non-consistent colors, which changed from channel to channel. There was a total loss of depth perception. No adjustments could maintain a sustainable picture quality.

Ultimately, the picture qualities on High Definition Channels were worse than Standard Definition Channels.

Wednesday AM – August 12, 2014

I contacted DirecTV again. We discussed all of the diagnostics done the previous day and it was decided a home call by a technician was necessary.

Friday Noon - August 15, 2014.

The first test the tech conducted was to check signal strength displayed on the main receiver. Each transponder signal was degraded. The various transponder strengths ranged from low 70’s to mid 80’s. But oddly - the signal levels were actively fluctuating as we watched the TV screen. Across each of the 5 or so rows of numbers, they would randomly and continuously rise and fall.

The tech appeared to be very knowledgeable. He worked methodically was very thorough. He inspected and tested the dish aim, examined all cable connectors. He closely examined the connectors at the power splitter.

The tech changed the power splitter, the LNB on the dish, and put weather proof couplings and connectors on all outdoor wiring. The tech did other types of update service to equipment.

After the tech did the service work – the signal test strengths ranged between 98 and 100 signal strength across the several rows of numbers. HOWEVER, picture quality was still not the same fantastic depth perception with the original rich, balanced color.

The tech said that he was only responsible for ensuring signal strength was at a given range. But he went beyond the call of duty to try to restore picture quality to their original state.

Despite everything the tech did improve the color - but even he could see that nothing he was doing would sustain color adjustment.

The tech finally change the main power splitter located near the dish. Still no help!

I tried adjusting color on all TV's once again. I was able to get close to where the pictures were. BUT I wake up on Saturday - and all color calibrations had again failed.

I made one last attempt to adjust settings.

This morning...signal strength is still strong. But color and depth perception on all TVs are horrible again.

No matter how many times I try to calibrate color and other picture quality adjustments - nothing seems to work or maintain sustainable changes for any length of time – on any of the three televisions sets.

I don't have a clue. Thanks.

What happens to the picture if you watch a Blu-ray Disk?

What Model Receivers are connected?

1 Model HR34-700 Genie

1 Model HR24-200

1 Model HR24-100

I have a Sony Blu-Ray player attached to the HR24-200

I do have a Blade Runner playing. It appears to be a better picture than on Satellite, but to be honest, my Obsessive Compulsive need to make the picture like it was - I have no doubt that I've managed to cause some of the color and picture quality to be less than it was originally.

For what it's worth, I have used my Blu Ray player - and of course with a Blu Ray Movie (which is about as close to 1080 P as possible) - in order to tweak the color settings in my Plasma and LCD. I haven't gotten to the LED yet.

Both set's pictures are better, but I don't think they'll ever be the same. There is a "grain" appearance that I can't fix.

I spoke with a man in Austin that repairs plasma TV's and he said that I'll probably never know what could have possibly caused 3 TV's color and perception to become distorted simultaneously.

The only thing I don't have on a surge protector is the DirecTV SWM Power Adapter, which is linked to all TV's via a coax cable that is attached to the main power splitter (mounted outside next to the Dish). So obviously all 3 televisions that are also attached to the power splitter via coax.

I live in a rural area where surges and power outages are common. So the theory now is that some power issue may have made it's way through the SWM Adapter via the coax...up to the power splitter and then on to the 3 televisions "at the same time".

Ohhhhh....I hate when stuff like this happens.

Did you go into the settings mode & make sure your receivers are set to output resolutions of 720p & 1080i? I find mine sometimes reset themselves to only 480i for no apparent reason. And one of the noticeable aspects is that picture is duller and the colors more washed out. It doesn't happen often, but it does happen. Maybe there was a simultaneous update or power surge that caused all of them to reset?

Signal strength should have nothing at all to do with picture degradation with a digital signal.

Yes, that is usually the first thing that I do if the picture ever gets a little off. DirecTV receivers will occasionally jump the set resolution setting.

However, in this situation:

I disconnected the satellite receiver altogether when trying to redo all of the color related settings. I didn't need it connected since I was playing a Blu Ray disc. Then I toggled the color settings from the TV menu as usual.

Now I did make sure that the ratio was set to "Full" (16:9). I don't use zoom or stretch features...or the 4:3 ratio either.

If the power issue did happen through the DirecTV equipment then I assume it could impact the TV itself. Sooo?

Like you I live in a similar place- SO I keep each receiver location on it's own UPS (Everything in that location) is connected through it.

Not for run time but for Clean & constant Power-- Surge Protection will only work once (and you may not know when) Then it protection is done there is no reset.

Wow...well, if surge protectors are a one time thing, then all of my equipment (receivers) and even my TVs might be fried somehow.

In my area power surges are more common than dogs and cats.

Well, still no progress.

I did use a Spears and Munsil disc to recalibrate all my TVs. NADA! The recal helps, but the next morning the pictures are out of sync again.



I'm totally lost. The only thing left is to call a pro.

Borrow another Known Good T V and I think you will find your stuff has been compromised - When you get your "NEW" stuff -invest in a UPS (1500) Brand of your choice-Power everything of Value behind it. NOT for hold over but Electric line conditioning -from Brown outs & Over Spikes - I think maybe that's what has happened.

Paying $800 -$4000 on TV's Additional $200 for UPS protection is Cheap Insurance. Old Tube TV's Could handle Flux in Power -PC Mother boards-DVD's AV receivers , Flat Screens are all Mother boards and can be dealt a Blow at anytime.

Please let us know your finding - Good Luck

YMMV

Are you using an HDMI cable from the DTV boxes to the TV's? Can you try a component cable to see if the picture gets any better? Just another suggestion for something else to try. I used to have Uverse TV and I noticed the same thing using an HDMI cable. Switched to component and the colors as well as picture was better. Still dumped Uverse due to the lousy HD PQ.
