Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: how to get rid of demo mode motionflow

Try some of these solutions:

  1. Turn GA_googleFillSlot("TL-IMU-Article"); on the TV.
  2. Simultaneously hold down the Vol+ and Vol- buttons on the front of the TV. Do not use the remote control.
  3. Hold for about 6 seconds

  1. Certain model TVs may turn off, others will not. But in either case, the Demo mode should be disabled.

SOURCE: Sony Bravia 32". After Powering On within 5

In order to properly diagnose the problem and provide a solution, the following information is required:

1) Model number (on the back of the set)
2) The count of blinks of hte standby light.

The standby light should be blinking in a repeated pattern of a count followed by a short pause then the count again ...

This count is an indication of the circuit that has the fault. With that information and the model number, I can list the likely causes and fixes.

Thanks,
Dan

Your TV is in store demo mode.

To fix this, access the TV's menu and find the option to run initial setup. At the beginning of initial set-up, you'll be asked whether or not the TV should be put into Home or Retail mode. Choose Home.

Sony TV KDL-40EX720 is faulty!


From your video, it looks like a mainboard, Tcon or cable issue.

You can try to contact 40 diag LED EX720 Series Internet TV Sony to see if they have spare parts for this. Those three items above I would target as the main problems.

Hi got sony bravia 40s2530 40 inch tv,woz workin fine but wen turned bac on came on 4 a few seconds then red flashing light 4 flash then 3 sec brk & 4 flash again & so on!any ideas?


Hi,
You can fix this yourself , having basic knowledge on electronics will make it easy but not withstanding you can get it a try.
Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care and this help in solving the problem

Does my 32 inch Bravia have a fan? There is a noise in the back of my tv that sounds like a fan running.


There are no fans inside your 32 inch Bravia. I don't know the sound you are asking about. Is it a high pitch squeal? Is it a low volume humm? In either case you may hav e a bad filter capacitor or a problem in the Dolby noise reduction filter. In any of these cases, the filter cap in any location on the board can create the first sign of a problem. For starters, always suspect your filter caps.

Sony Bravia 32 inch HD LCD tv has vertical lines going down 2/3 of screen. No idea what problem is. Tv is less than a year old, but I have lost the receipt. Anyone had this problem or know what may be...


We had a similar issue although our Sony Bravia was 21 months old. We were told by an engineer that the panel has failed and that the cost of replacing it would be about 900. We were also told that this is a very common fault and that the "normal" failure time was within 18mths to 3 years. If you registered your TV purchase with Sony, it might be worth contacting them with the serial number to see if you could get it repaired under guarantee. We have now bought a TV with a 5 year guarantee!!! (not a Sony!!!!)
