Sony KD 49XD8305

My picture has just started to "pulse" from clear to slightly fuzzy, holding on each pulse for about 3 seconds. Can anybody offer a suggestion to cure this. I have tried the three suggestions offered on the Sony site, so now need  more help.

Hi @irnbru59 

What were the three suggestions shown on the Sony site?

[irnbru59]

(1) Lower the Digital noise reduction

(2) Adjust the Sharpness

(3) Reduce the Gamma value

Hey there, try the below: 

1- Disconnect any external devices connected to the TV. 
2- Unplug the main power cord of the TV, and plug it back after 60 seconds.
3- Check if your TV has the latest software version: PKG6.7210 (Help - Status and Diagnostics - System Information):

If not the latest, please find the below link to update the TV:

4- Clear the cached data from the TV internal shared storage following the below steps:
(Home - Settings - Device Preferences - Storage - Internal Shared Storage - Cached Data - Clear).
5- Perform factory reset following the below:

I have done all that you suggeted with no chabge. Even the "SONY" basic start screen throbs / pulses. I guess I have a part that has failed.  Thanks for your input.

Hi, 

I am delighted to say that this morning my TV has returned to normal (after several weeks of pulsing fuzzy pictures).

Many thanks to my helper, I am sure this was the prime cause of rectification.

thank you

I regret that the TV has started pulsing again, however upon repeating the previous exercises, I found that 

HOME / settings / device preferences / reset / factory reset  -  did no longer have sub screens, but instead just bumped me straight back to the HOME menu.  I have manged a reset by unplugging from the mains, holding in the 3 button switch on the back, replugging and then releasing the switch when the data clearance message arrived, followed by the tedious set up procedure !   This time there is no change to the pulsing screen.  Help!

Hey @irnbru59 I believe at this point you will have to contact Sony, if you can take a video of the issue and provide it to them, that would help them identify the issue and assist you.
