Pioneer SD-532HD5 - Picture Bowed on sides only on 1080I

Using Dish VIP-622 or Sony Blu-Ray when setting device to output 1080i signal, the picture on the TV becomes somewhat distorted (bowing in on left and right).

On Dish, picture for setting 480P looks fine.

Any suggestions on getting my Hi-Def pic back?

Thanks in advance,

Pete

    Thanks Dan,



    Any insight would be appreciated.

    Dan,



    I really appreciate your help and your response.



    I agree that it is not worth spending that kind of money on this set and have begun looking into a replacement.



    Again, thanks for your help,



    Pete

I had the same problem, and I had a TV guy fix it. It was just a diode or something on the convergence board, and it took him all of ten minutes to fix it once the board was out. The trick is knowing what part to change, and the skills to do it, obviously. It was year 4, day 360, of the five year warranty when mine went, so I don't know what it cost, but it would have been all labor + $2 for the part, but they actually fixed it rather than the typical swap the whole darn board.

The problem you are describing is known as a pincushoin problem. I'm a bit surprized that you only see it on the 1080i signal though. I've inquired at my Pioneer contact about this and will update this soon.

Stay tuned...

    It turns out that this is a known problem for these sets. The recommended "fix" is to replace the convergence board at a cost of $375. I wouldn't recommend that kind of investment at this point. It is possible that the convergence ICs are starting to fail and that can show up in this manner as well. If you are to invest in this at all, I would try resoldering the entire convergence board first. If that does not resolve the problem, replace the convergence ICs (STK392-110 I think) and report the results here. Other than that, you are best to invest the $375 into a newer set.

Upgraded to Hd and tv started messing up. Double images for first 10 minutes and sometimes tv picture goes off and lines up and down.


Your HDTV is capable of up to 1080P resolution. SDTV (standard def) signals are 480i; EDTV (enhanced def) is 480P; HDTV are 720P, (there is no 720i) 1080i and 1080P. Generally, those modes ending in "P" look better than those ending in "i". 1080i is the highest possible for broadcast TV, but BluRay disks and Directv have 1080P display capabilities.

The double picture you're describing sounds like the TV is set to display only standard or enhanced def signals while the Dish Network box is supplying it with HD signals. You should locate the control for the TV's resolution and make sure it is set to "1080P" and then set the output of your Dish Network set top box to the highest output it offers. Do the same for your BluRay player and any other devices, too.

Once set correctly, you should have a great picture once again. I hope this helps & good luck!

Dish vip 622 and vip 722k frequent picture freeze and restart


Sounds like a signal strength issue. You may have either a low signal or something like a tree limb is blowing into the signal path dropping the signal strength to a point low enough to causes issues.

Cant figure out to hook up keeps saying no signal with hdmi cable to tv and blu ray put in


What kind of TV are you hooking the dvd player up to ? You may have to go into the TVs menu and set the input to the proper resolution or input style to see a picture. The dvd outputs a 1080i and if the TV is set to 720p it may not show a picture, the dvd output can also be changed to match the TV.

Screen resolution


There is only one type of ''output'' which currently outputs 1080p and that is blu ray players.
Sky HD, free sat HD and even HDDVD's only output at 1080i.

Your TV will automatically output at its highest possible quality from the signal its receiving. Please re-clarify if you are using blu-ray, if not, go and buy a new Blu-ray player!

Mitsubishi 55 in. 1080 series


If I remember correctly, this TV has a couple of constraints that will cramp your style:

1. It supports 480i, 480p and 1080i. NO 720P
2. It has component video inputs, but NO HDMI. (as you stated)

There is no easy solution here, because I've never found an upconverting DVD player that would upconvert anything past 480p using the analog component outputs...

So..

Perhaps you can find an Upconverting BLU-RAY disk player that may allow older DVDs to be upconverted to 1080i via the component outputs.

MOST Blu-Ray players allow 1080i output via the analog connections on Blu-Ray discs, so perhaps there is your solution.

Upscale from 480p Signal via HDMI


ok the problem might not be with your receiver it is with your direct tv settings. Double check to make sure you go to the format and set it up to be fixed or 1080i whichever will give you the highest resolution. Check your manual for the direct tv receiver. If this is all correct for the DTV then you must go into the setup on the receiver and at hardware icon toward bottom check on that box, now goto the hdmi settings and make sure it is set to through. this will allow the best picture with no upscaling which will degregade picture for blu ray. so your direct tv will be only 1080i but very impressive. if you still want to upscale you can then you have to change the hdmi settings from before to upscale 1080p . I just hope that your dtv can output 1080i it will give a better picture than 480p even if both are upscaled to 1080p
Oh i forgot to ask if you are connected through hdmi to the tv. Hdmi is the only option for upscaling

Upconversion to 1080i playback


Hey smittybd,

According to information provided by the manufacturer, this specific model DVD player is only able to provide upconverted 1080i images via its HDMI output and a maximum 480p resolution using its component connectors. Please keep in mind that while component cables are able to support 1080i and 1080p resolutions, not all hardware (TV's and DVD players) will support these resolutions through component connections.

If you're having difficulty locating a model that specifically supports 1080i resolution images through its component connections, you may wish to try visiting individual manufacturers' websites for more information. Some companies (such as Sony) will provide detailed information regarding what each type of connection is capable of in their owner's manual documentation.

Hope this helps you out.

Sincerely,
Aaron

My tv shows its's geting 1080i only


1080p signal... THE MITSU. WD-65731 has a resolution of 1080p its just the res your PS3 is pumping into your screen is loaded with a little bit more pixels than you 1080p res MITSU. I suggest getting a MITSU WD-57731 since it has a 1080P/24 input. and has great clarity and HD ample for the BD of your PS3. however the differences in picture rate and quality is very small. goodluck.
