    Re: Sony KDL-46XBR4 13 blinks

    Alright so I disassembled it down to the CCFL's, and clicked the power on button. I checked all of the ccfls as they lit up, there was about 24 of them and I noticed that one of them was flickering. Would the flickering CCFL be the cause of this problem?

    Heres a video:

    its the 4th lamp down from the top, the TV turns on, and as the lamp starts to flicker the TV turns back off.

        Almost certainly (>90%) the problem. Replace it or do the bypass - your call.

            Good news here! Turns out the flickering was due to a loose connection of the ccfl to the side connectors. There was a couple of loose connections than the flickering one, I fixed the connector and rehooked every ccfl, now the TV actually stays on! =) Lets hope it was the only problem, reading alot about this TV i feel the tab bonding problem may arise (lets hope not!)

                I hope that fixes it! Nice fix if so...

                Someone else on these forums had a similar problem, arcing backlight connector due to it not being completely secured.

                    So just put everything together, theres a little uneven lighting from the backlights but not too noticable, especially when the picture is playing. But everything is working great!

                        You probably smudged the screen, it can be cleaned on the inside with a cloth.

                            Sony KDL-46BX450 Inverter Troubleshoot Logic
                            by caseyjay_48
                            I am currently on a troubleshoot of 46” Sony KDL-46BX450 tv. I came back from Washington to Texas on medical emergency and had to leave all my tools up there. All I have is a couple of screwdrivers and a dvm. I wish to ask the community a troubleshooting question. Please forgive stupid questions as meds I am taking produce brain fog.
                            I have well maintained Sony KDL-46BX450. It went black one day. After turn-on, I get solid green light and Sony logo in screen center for about 1-2 seconds, then black. No blinking LEDs, no hissing. Flashlight test shows screen characters dimly viewable,...

                            Sony KD-65A1 Repair – 4 Red Blinks Error
                            by AK_777
                            Hi everyone!
                            I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

                            Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

                            Sony A1e 5-blinks help
                            by jchon
                            Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.

                            I found the service manual, which was critical to know where to probe.
                            https://www.manualslib.com/manual/20...1e-Series.html

                            With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.

                            Unfortunately the 5-blinks...

                            Sony XBR-65X850D 2 Red Blinks
                            by Nicktronic
                            Hi all,

                            I have the subject TV and it will work normally sometimes but suddenly go black and give the 2 red blinks blink code. When this happens, I check the power supply board voltages and all I have is the Standby 3.3V and BL_ERR 2.2V. When it's working normally, all power supply board voltages look normal and stable. I've checked the backlights with a tester and they all test good. I've also read that the 2 red blinks is a faulty power supply board, so could it be throwing up an erroneous BL_ERR?

                            Any Sony experts out there that can help??...

                            Sony 75X9400E TV.. 5 Red blinks
                            by dumbdd
                            I was using this TV for 5 years before it stopped working. I like this TV and would love to fix it myself.*

                            When I press the power button, the white led comes on (sony calls the module smart core) and then it switches over to 5 red blinks. No screen, no backlight, no relay click, nothing. I have disassembled the tv and found the service manual for 75x940e online. The manual suggests a faulty power board, TCON or the panel.**

                            The standby pin is at 3.3V. Fuses on the mainboard and TCON are fine. Caps on TCON also seem to be fine. When I turn on the tv the white led...
