Sony KDL - Recent Questions, Troubleshooting & Support

go to service center and get it repaired.

Sorry I can't help on this one as I don't work on Sony TV's

You have to enter its service mode option to do a factory reset. Just visit these sites. I'm sure that you will get the details. https://homenol.blogspot.com/ https://elektrotricks.blogspot.com/ https://electrohelponline.blogspot.com/ If you wish to get some details; check the site linked here. Pull up older posts. Surf the site by type in the brand name of your TV, at its search box at the right column. View the sites by desktop computer or by Webview by mobile.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. https://homenol.blogspot.com/ https://elektrotricks.blogspot.com/ http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given. If blinks continue without any pause, the main board is faulty. Search the sites by type in the brand name of your set, in its search box at the right column.

I had the same issue with my sony kdl40ex500. All I did was update the firmware and it fixed it. You can get the update at the SONY website for free.

I have the same problem. I have the Sony Bravia KDL-40S4100. I can't get it off channel 2. It won't work with the remote, and it won't work on buttons on the top of the console either. The power button on the remote is still able to turn the TV on and off, but aside from that, everything else is frozen.

While looking found this:Found this service bulletin for sony KLD KLV40EX600 not austalia model but think KDL will be similar Model No: KDL-32EX400 KDL-40EX400 KDL-32EX500 KDL-40EX500 KDL-46EX500 KDL-55EX500 KDL-32EX600 KDL-40EX600 KDL-32EX700 KDL-40EX700 KDL-46EX700 KDL-52EX700 KDL-60EX700 KDL-40HX700 KDL-46HX700 KDL-55HX700 KDL-40NX700 KDL-46NX700 KDL-52NX800 KDL-60NX800 SUBJECT: Counter measure for Intermittently 5 times standby LED blinking SYMPTOM: Customer may report that intermittently after AC OFF/ ON (or Deep Standby/ ON), TV will shut down with LED blinking 5 times. If set is placed in Standby, then On, symptom will re occur. If AC is removed, set will work normally when AC restored CAUSE: Timing mismatch of I2C communication causes interrupt signal inside TV. This causes TV to shut down with error 'Standby led flashes 5 times' SOLUTION: This is a user correctable issue - Where possible, please refer customer to Sony Website -(or ) and search for relevant model to download correct update. If the unit is in Workshop, please perform update as per Instructions.

Sure, blame the kids. Could it have been a sporting event and your team lost? Just kidding, dump the screen and case. Sell the boards on ebay.

Sounds like main board fault. These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully.

I simply followed these steps with a surge protectorpress the power button and hold upThen hold up with the power buttonthen let go of upand let go of powerworked with my kdl-55ex720

If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV.
I will forward a link to a page where you can get more information and troubleshooting steps for this issue.

Please perform the steps provided on the page. If the issue still persists then service of the TV is required.

It will be either BM board (Video Processor board) or Tcon Board (top side of panel). I have similar problem...my TV turns on, lamps turns on (you can see them from back side panel holes) but just a dark blue picture appears with no image (like picture when external input is selected without signal), no OSD appears....some times I can heard audio (using Antena).
I'm thinking getting the BM board.

The power trip off means that the main board has a short and so there is a high current drain which triggers the protect circuit to work and switch off.
So to trace it requires that the different driver sections be checked for possible high drain or heating. Check for dy points soldering.

clean connections for T-Con board

This is what's happening: a part from your tv has failed; when you try to start the tv the failed part acts as a short and draws a lot of power, way more than it's supposed to do; when this happens the voltage on the power source drops - this triggers the autoprotection system of the power source which shuts it down - the standby led goes red; when the power source stops the power to its autoprotection system also stops, so it remains powered only by the charge in the filtering capacitors; when these capacitors naturally discharge the autoprotection system gets disabled , the power source restarts and the cycle begins again.
Since you get an active background lighting - the screen gets gray - it means that the power source, inverter and most likely T-con boards are ok. That leaves only the image or logic boards as the one s with the faulty part. The only way to know for sure is to open the tv and test them. This is a job for a pro, there's nothing more you can do to it.

Hi 4 Times Blinking is for BALANCER_ -------> Panel Balancer Error Kind regards. Rehan
