KDL-70r550a picture pauses from time to time

I just bought this 70 "tv, #KDL - 70R550A, for my home theater and for the first two days I was pleased with the quality of the image. However, after that the screen would reduce and turn it back on every time some time, as the TV flickered. The sound is not affected. The flashing lights at random and sometimes do it 4 or 5 times in 10 minutes approximately. It doesn't matter if I'm watching a Bluray, DVD or games. I checked the firmware and it's the latest on the Sony Web site.

It becomes very annoying. I tried to reset the TV, changed different image modes and off motionflow, changed different CineMotion, but it has not changed. It was also very inconvenient when we watched a movie with our guests last weekend. They asked if we bought a refurbished tv!

I have rehooked man of Vizio LCD to see if this flashing problem was due to some loose connections. The last 2 days this Vizio never blinked, nor is he already done it in the past.

Because the TV is used in my home theater, it served only as a monitor, so all the sounds are diverted to my 7.1 speakers. The TV is connected via a HDMI cable to 25PI, high speed with ethernet v1.4, to a Denon AVR 2807 receiver. All my A / V components are hooked to the receiver. All video signals are converted to 1080 p via the receiver, regardless of the resolutions. This setting has never been changed since home cinema has been implemented.

I googled the problem but could not find anyone with the same problem. I read the Support section of the Sony Web site and found that video problems may result from the use of a receiver. Although he did not indicate what types of problem. She says that maybe some amplifier/receiver is not compatible with the Sony TV.

I found this counter intuitive that a receiver is not compatible with this Sony TV. Avoid all the problems of compatibility with all brands. It's like saying that I have a Sony DVD player for watching a DVD from Sony.

I hope a Sony technician or someone could show me how to solve this problem quickly. If I can't get this fix in 2 weeks, this TV is going back to the store and the end of my 30 years of support of Sony.

Donghun - please try the following steps:

NOTE: This solution will also apply if the photo or video is blinking and triggering intermittently.

If there is no picture and the TV screen is completely black, it may be a loose connection or incorrect setting. To resolve this problem, follow these steps:

IMPORTANT:

  • This solution assumes that the BD drive is connected directly to the TV. However, if the BD player is connected to an Audio/video (A / V) receiver, the steps below about TV should also be followed for A / V receiver.
  • If the model-specific information is required to complete any of these steps, see the instructions supplied with the product. Manuals are available online through the manuals/Specs/warranty link on this page.
  1. Make sure that the TV is set to the video input appropriate to receive the signal of the BD player.

    NOTE: Depending on your TV remote control, the remote control may have a button TV/VIDEO or INPUTS that can change the video input of the TV.

  2. Check that the video output of the BD drive setting is set to Auto or the type of connection used.
  3. If the problem is not resolved, turn the comics and TV player.
  4. Check the cable between the comics and TV drive to ensure that it is correctly connected to the two products.

    NOTE: For HDMI® connections, try the following steps:

  1. Turn off the power on the drive of BD and the connected equipment.
  2. Disconnect, then reconnect the HDMI cable.
  3. Re-turn on the power to the connected equipment.
  4. Turn on the power for the BD drive.
  5. In the configuration settings of the screen/video, set the BD / DVD - ROM 1080/24 p output OFF.
  6. Set the output HDMI Deep Color off.
  7. Together the X.V. color output OFF (this option is not available on some models).
  8. Make sure that the HDMI control parameter is set to Off. If you use a non sony BD player, this parameter can be called control AnyNet function or CEC.
  • If the problem is still not resolved, try to reduce output resolution by using one of the following methods:
    1. The supplied remote control, press twice on the button (available only for some models) VIDEO FORMAT.
    2. On the front of the BD drive, hold down the STOP button for about 10 seconds.

      NOTE: Some TVs connected with an HDMI cable may not bear a 1080 p signal. If the BD player's output a 1080 p signal, lowering the output resolution can solve the problem.

  • See the software/driver from the site Web Sony® support for firmware updates.
  • If a firmware update is listed, follow the instructions in order to acquire the update.
  • If the problem is not resolved, try to replace the cable between the comics and TV player.

      original title: remove duplicate photos

      Unwanted copies have file names with

      My computer with two hard drives and 2 starting systems has the car crash in the solid state. When I got the new drive and tried to restore from time capsule, I lost some data. How can I see what backups are on the time capsule? My laptop is also saved to the time capsule. Everything is in 'Data' when I look through the Airport utility. I think that the information that I've lost are still there since I was a Capsule 3 to.

      Time Machine backup to a sparsebundle.

      The sparsebundle will use the share name of computer. So, it should be obvious who is your Macbook and that is your Macpro.

      Open the sparsebundle in Finder and keep open the subfolders until you get to the backup of each separate hard drive...

      You has of course set the exclusion in Time Machine?

      By default, Time Machine will exclude your second drive unless you have included it. Did you?

      Once you get to this level during the backup, you can do a full restore manually whenever you want.

Because I travel abroad from time to time, I need to use another sim card when I'm outside of US. So if I order a T-mobile unlocked iphone7, he will accept my sim card from a foreign carrier? In addition, he will accept my 2nd sim card which is Sprint (my sprint sim card is not related to a device)?

    • How can I copy files from Time Machine without going through Time Machine

      I had to do a clean OS X El Capitan on my iMac install because something prevented it from closing properly. I now El Capitan without any of my old files and applications.

      I want to copy my Time Machine backup, but the record has been marked by a red dot. I can't transfer manually. I don't want to go through a Time Machine, because the last time I did it, it just restore the old configuration that basically had the problem that stopped my computer of closing.

      How can I manually copy the files?

      Do not restore complete.

      You can 'enter Time Machine"to select files and folders to restore.

      Alternately, when restoring from Time Machine backup, customize the restoration as follows: under Select the information to transfer, select only your previous user account. Do not select 'Applications', 'Computer and Network Settings' or "Other files and folders". Deselect these choices. Potentially corrupt applications, lists of properties and changes in the operating system will be migrated and will be any problem that may have been caused by them.

    • Cannot find files on clone super duper, I can restore from Time Machine backup?

      First of all, my apologies for cross posting.

      I hope I can explain my situation with enough clarity so that someone can help out me. I feel a little bit of panic.

      I've had a Mac mini that I sold so need to wipe. I first backed up using Time Machine on an external hard drive. Then, I used Super Duper to clone on a second hard drive. I didn't need a bootable copy of the training, but need access to data, applications, etc. on it from time to time. My intension was to access the data I cloned and stored on the hard drive of my current Macbook Pro. Well, that day came and I went to access my cloned copy of the mini and only see a list of users. I'm not able to find files, documents, and etc.even if I use spotlight to search for. So my questions are:

      1. Can I view the contents of the double machine differently to see more than a list of users? (that is WHERE IS MY THING?)
        1. I have error somehow in my approach?
        2. If I made the mistake with the super duper close, can I restore my time machine to the top of an external drive on another external drive? I want to restore my MacBook hard drive.

      Thank you!!

      I was running just an another SuperDuper! Clone.

    • Why does predictive mode spontaneously to go out from time to time?

      Why settings - general - keyboard - predictive spontaneously turn off itself from time to time? I'll type a SMS or e-mail, and sometimes using the dictation feature, but sometimes the predictive mode disappears. Given the complexity and the hidden nature of the premises, is not something that you can meet by chance, so I can't understand why.

      Maybe there's another secret gesture or key combination which is the cause. If this is the case, we hope, there is another secret gesture I can learn to cancel his disappearance. It's a pain to go back and manually reset.

    • Impossible to restore a file from Time Machine

      I messed up a data file and tried to restore from Time Machine. It produces the message "the operation cannot be performed because you have not granted access to the Finances of 2016 VDJS. I use an iMac 2009 beginning running OS 10.8.5. I checked permissions, and since I'm the only person using this computer all read - write permission. The version of the file I am trying to use to replace the messed up one was recorded only a few days ago and should have the same permissions. I apparently can't use disk utility to verify or repair permissions on the time Machine if the problem is with the saved file. I have another backup using DropBox, but I organized "intelligently" so that it records the changes made to the files they are saved on the computer, if the vehicle has currently the messed registered version. Others have reported this problem as a result of this message on the permissions, but not in similar circumstances, while the situation I'm in.

      Hi - I had a late 2012 27 "IMac El Capitan 10.11.4

      A few days ago a reboot is required after (I think) an upgrade of the El Capitan, but the machine hanging after the reboot, showing a gray screen, a small circle in the middle with a grey diagonal line in the circle. Under the circle turning another circular graph which gives the feeling that I have to wait for the machine to do something.

      In any case, the machine was stuck in this mode then after a lot of messing around, I went for a full restore from Time Machine (which is held on a NAS). Everything seems to be going smoothly, taking 20hours. He said full restoration and did a restart, but I am now stuck on the circle of greg with the diagonal line through it again that does not heal a re-boot. Utility disk V13 (450) shows on the left:

    • Satellite L855-123 freezes from time to time

      Hello

      My laptop freezes from time to time, especially just after that is (re) starts. Most of the time the audio or the video freezes for a few seconds (any program I use), it affects everything else too (for example, when music freezes, google chrome will act weird as well), but I am able to move as much as I please.

      In Event Viewer, there is a lot of "iastor, id: 9" since the 20th of this month (the day all gel started to happen). But as of yesterday, it seems to be have been replaced by "atapi, id: 11» I don't have any new software before all this happened?

      I looked around and tried a couple things that have helped others: off Link State Power Management; made sure all drivers have been updated; Uninstall Intel Rapid Storage Technology. Nothing seems to work here however.

      If all goes well, there is something else I could try before I have to go through the hassle of reinstalling windows 7 or get new hardware.

      Thank you.

      I guess you do not reproduce this problem of gel.
      It very difficult to talk about issues that cannot be reproduced or occur occasionally.

      But you mentioned the 'file iastor in your ad.
      Iastor belongs to the Intel AHCI / RAID or SATA driver package.

      So I think that the problem is related to the HARD drive or the HARD disk controller.
      I recommend you update Intel® Matrix Storage Manager and Intel Rapid Storage Technology driver to the latest version (check page Intel).

      If this is insufficient, recover laptop using Toshiba recovery disc.
      In case this is not enough, you should check if the internal HARD drive might be the occasional reason for this system of freezing.

    Maybe you are looking for
