Sony BRAVIA - Popular Questions, Answers, Tips & Manuals - Page 3

it is hard to be sure what the issue is but are you sure it is not the cable or hdmi connection are you using an air antenna or actual cable or satellite signal this issue sounds like a non cable service issue meaning you have an air antenna hooked up is this true?

Remove the LVDS cable, the one going to the input of the tcon board and see if it goes dark, if it does the Tcon board has failed

You have issues with the Tcon board, this is a case where you could try putting it in the oven and baking it, below is a video on how to do this, if it doesn't fix the issue and I think it will in your case you will need a new board

HI PLEASE SWITCH OF AUTO MODE FROM LED THANKS M NASIR

There is no way to really check a T con without a lot of test equipment, only thing that is serviceable on that board is the small fuse that is by the LVDS connector...

Serious! If the TV is new, you may check your homeowners insurance for a replacement. The Power company can Verify the power fluctuation for you. When an appliance receives a Power Surge like that, the sensitive electronics are damaged or weakened. For PROTECTION: Get a 1000Watt UPS and use it between the house power and the TV. http://www.tigerdirect.com/applications/SearchTools/search.asp?lowprice=50&highprice=99.99&keywords=1000W%20UPS&cat=&mnf= Try This.

Check all fuses. If you have power going into the power supply board..but none coming out of it...I think you have found your problem. Get a new power supply board.

Test the power supply voltages after it shuts itself off, mainly the PSON voltage as that will determine if its a main board issue or power board

Try replacing the Tcon board

The finger below is pointing to the HDMI ports. If your TV doesn't have these ports then you don't have the ports available.

HI PLEASE REPLACE MAIN BOARD OF THE LED IN THIS CASE THANKS MUHAMMAD NASIR

I would bet on it being a panel issue, you can try a new t-con but I don't think its going to correct it, may be time to buy a new set

There may be a "Power saving" feature on the TV. Check in set-up and adjust time for auto shut off.

Is the tv new or has it started to do this recently ?
Try to eliminate the obvious.
Does the remote continue to flash when you release all of the buttons? Is it a stuck button ?

If you cant' see the remote output, try using your smartphone camera. Most phone cameras will capture infrared light ( invisible to the eye). Aim the remote at the camera and see if you can see the flashing light, which is data being sent to the tv. When you release the buttons does the flashing stop ? If so remote is ok

Next turn all of the lights off in the room with the tv. Also turn off any lights that may shine in from other rooms. Try using the remote

If your tv functions normally, you may be getting interference from your lighting. Some LED and CFC fluorescent lights flicker at a rate which may be close to the remote IR output frequency.

If turning off the lights fixes the issue, turn on each light to isolate the issue. Replace the bulbs with ones from different manufacturers.

Let me know

I once had an HDTV with a similar problem. If I turned it back on, it would make a loud BUZZ-BUZZ-Buzz noise for about twenty seconds before coming back on. I can only guess that the problem is the TV drawing too much power from a circuit that can't support it. Do you have many electronics plugged into the same socket? Is the TV going into a splitter? Try isolating the connection and the TV might have better luck. No guarantees however. If it's the same problem I had, then it will do this no matter what you hook up to it, as you seem to have at least partially discovered.
