Great info. There’s another fix which is to remove that bl err pin from connecting to the power supply and send it to ground. Works the same way. Looks like Sony may have engineered their led tvs so that power is shut down following a single backlight or led pixel failure. Their advice points towards board failures when in many cases it’s just the sensors sending a signal to kill power for minor issues. 4 red leds can signify the display inverter failing but the test is unplug and follow advice for a factory reset after a few hours. Often you’ll get the tv working for 5 minutes or so clearly demonstrating that there’s no major hardware or board failure. Poor connections or sensors can result in the 4 red led blinking shut downs.
Great video. Thanks. I have a Sony KD-55XE9305. It powers up and displays fine for about 7 seconds and then automatically shuts down with red standby LED blinking four times. Would you think the mainboard is faulty and should I try the same diagnostics? Or would you think its the inverter or backlight issue? Many thanks.
IIRC, I had to ground one of the pins from the ribbon connector on the main board that connects to the inverter board. Probably one or some of your LEDs are fried and the inverter board is sending an error signal to mainboard which in turn switches off the TV.

my friend. I have a sony XR-77-A80J have 4 blinking lights can it be similar issue mainboard ? turn TV on and once you see SONY logo the tv will shut down and blinking 4 red lights. sometimes it keep rebooting itself few times and then stop but everything it starts up about 10 sec and shut down. should I disconnect panel cable from mainboard and see if 4 blinking light still come on to rule out panel issue ?

Hello sar mere pass same sony ka bord hai us me bhi same problem hai lekin ic rt8292ah ki pin no. 7 me key press karte hi 10 volt aate hai or set band ho jata hai or 4 time blinking deta hai Sar kuchh solution dijiye na ic ka problem to nahi lagta muje? .
@@VcoreLC ok that’s what I was hoping would be cool if I could just take screen off the 900H and put on the 900E but probably won’t work so hopefully I could just try swapping lil parts. Thanks for the Reply bro
Hi, do you have seen a 8 times blinking ? I had a Sony KDL-32W655A and the TV had this issue. I press power on button and the TV keeps blinking 8 times the red light.

After I shutdown the TV, I unable to power on the TV again until I use the same combination of keys. After 1 week, the TV never will power again. Totally dead. By curiosity, the small light in digital audio output is off too. I fixed the issue swapping the board. Code BKX 188815331 .
@@VcoreLC I already did. But it do not help. I used the method to reset the firmware using the TV buttons at backside. After that, I updated the TV for the latest version of the firmware and I did it the reset again. But the issue still occurred . After some days, the TV was 100% dead. By the way, for the sake of testing, I changed the power supply for a new one and the issue still happen. The TV uses a external power supply.
