Chosen Solution
We tried so many times But my to is not getting on after power on the tv ,it seems that it try to on but after some seconds the red light blink .It blink 6 times it will the same 3to 4 time and then go back to standby Also want to know What does it meen when red light blink 4 times Plz let me know who can it be solved
Take a look at this. 4 red blinks- can be LD board or main logic board, check inverter board wires for arcing to ground 6 red flashes- backlight issue, bad main board, or power board or inverter boards- check standby volts on power board. “backlight on” volts should be 3-5v from main logic board then 24v to inverter
The 6 red blink code on Sony is usually a fail safe on the main board for plasmas… Usually set off by power surges brown outs and dirty electricity, this is done to prevent fires and further component damage so the customer will send the unit into Sony to get its components checked. This is a unique feature for Sony plasmas as they are carrying a high amount of electricity. Google or YouTube Sony Bravia reset. You will need a compatible Sony remote to perform the reset. I have fixed 3 2012 models and one 2011 from the 6 blink code using this method and 3 of those units have been functioning great after 6 months. A lot of repair shops easily misdiagnose it as a power board issue… Guess they don’t know how to use google. And there is usually nothing physically wrong with 6 blink tvs it’s just Sony trying to cover their ass at the time so there was not a recall since they were losing money on production when the units came out, similar to the PS3. hope this helps you all out ifixit community. - Brandon
Per Sony site, unplug for 3 minutes if your T.V. picture goes out and you have blinking red lights. If still have a problem and T.V. is plugged into a power strip, then unplug for 3 minutes, then plug directly into wall. The power strip could be bad. (https://us.en.kb.sony.com/app/answers/de…) It could also be a backlight problem of some sort. If you can view T.V. again, and want to see error codes, do the following: Turn T.V. off. Quickly press “Display”, “Channel 5”, “Down Volume”, then “Power”. Press “Power” again if nothing came up on T.V. See error codes. Press “Power” again, then again, to return to normal T.V. (https://electro-medical.blogspot.in/2016…) and (http://tampatec.blogspot.de/2015/03/sony…) I have same problem with my T.V., Sony kdl32xbr4. I already know I have a backlight error of some sort, since part of the screen is slightly darker. The codes verified that. I also had the 6 blinking red lights with no picture at all. Unplugging for 3 minutes did reset the picture. Error 6 was listed on my T.V. as a backlight problem. Though I do not know for sure if Error 6 is the same as the 6 blinking lights, since the blinking light happened when the picture went totally out. The backlight partially went out a few month ago with no blinking lights. I will eventually need to take my T.V. in for repair but do not currently know what the cost will be. I am hoping it is worth repairing. It has been a great T.V.
I resolved the issue by solder and ground the pins at the top of the backlight terminal,
Hi @clarkenick3 A 6x blink error code is a panel backlight failure either in the G board, the Panel module or the BMX Board. Here’s a composite image of the error blink triage chart and the 6 blink error troubleshooting flowchart taken from the service manual which may be of some help. (see p.3, that shows that the 65w857c is also listed in this manual)
(click on image to enlarge for better viewing) If it is a board or perhaps the harness, then it will be cheaper than a new panel (if you can source one) and definitely cheaper than a new TV
Save$ Big bucks on repair . 5 goods taps on the back of TV and your back in business. if that doesn’t work try again.
I disconnected the Wi-Fi board and the unit fired back up plugged the Wi-Fi board back in and it still works . I will let you know when itvflashes 6 times again. Oh by the way I replaced the power supply board prior to unplugging the WiFi board.
Solved: I don’t know which of these fixed it, but I did all three and it works now. Took TX to the garage and using an air compressor, blew air through all of the vents/grills. Lots of dust. Compressed air can have a lot of moisture if you live where it is humid, so be careful. If you don’t have a drier on your compressor, maybe use canned compressed air designed for electronics. Gently laid the TV over on its face (protected with towels) and lightly tapped on the back in several places. Finally, with it plugged in, I held down the power button for 30 seconds. Seemed to have worked. Also, plugged it directly into the outlet and avoided the power strip.
Usually bad connection. I removed 4 screws holding the tuner board between the power board and main board. It has a long connector. Took it out and cleaned the contacts. TV working OK .
OK, this may help some, I turned my Sony KLD 550 back-light from 5 to 7 and the TV instantly turned off. Then went into an endless startup loop because the back-light is failing and the TV will not run with it set to 7. The red light at the front of the unit confirmed there is an issue with the back-light because it flashes 6 times at each boot-up. It would boot to the Sony Logo & would then switch off & start all over again endlessly. This is because the auto light sensor is telling the TV to brighten the back-light back to 7 because it is in a dark room but the back-light cant handle it so it shuts down. I could not even do a hard reset using the TV buttons because it was so far out of wack & the TV could not boot far enough to let me do it. I tried for hours doing every hack on YouTube & the forums but nothing fixed it. Time to think outside the Box. Now U might think this is BS but to get around this issue and get the TV to the point where I could do a hard reset I got a super bright LED Torch & shined it straight into the light sensor on the front of the TV at boot-up. This made the TV turn down the Back-light at boot-up, which allowed the TV to finally well Boot-Up. Then I instantly got it to do a hard reset and when this was done I turned the back-light down to 4 & put brightness on MAX . It runs like a dream again now & I can hardly tell the difference in brightness or picture quality. At least I don’t have to go without TV and it gives me time to buy a new one now.
Same problems! Thanks for the answers!
this is what happens trying to turn on my tv
Try pointing a bright light at your screen if it power’s on all the way turn off the back light,if not it’s your power supply try tapping on back of tv just replaced mine again after 5 years it’s important to keep the backs clear of debri so they run as cool as possible
Thank you so much
for your reply Hutchinson. But I’m not sure about the test I should try. Do I have to do it with the power on, during the normal start? I’ve already changed the power board, with not any difference (I’ve got 2 power boards now!). I’m worried a part of the linear led lights are broken, but I’ve got no idea how to fix it, if it’s the problem.
So if you have changed the power supply and it’s still doing it it leads me to believe that you have a backlight problem and the only way to fix this is exactly what you are fearing get the brightest light possible or put the tv in a extremely well lit room so during start up it won’t call for the backlight to come on once it powers up go into your settings and turn it all the way down or off If none of this comes to a resolve then you most likely have burnt row of leds
