    Sony XBR43X800E T.V. will not turn on.

    This set is 3 years old and will not turn on first time in the morning. I have to unplug it from the wall socket for about 30 seconds, plug it back in and will turn on. From there it will power up throughout the day. This is using the remote that came with the set. I have found that when it is not used for some time "overnight" is when the problem happens.

    I did not unplug it for more than 30 seconds for fear of losing all of my personal settings.

    There is a power block that is in between the 120v house current and a secondary lead that plugs into the back of the set (19.5 volts). When problem occurs, I did find that there is 19.5 volts out of the lead from power block.

    Having had experience with repairing older style CRT sets does little good with these newer one's.

    I believe that the problem is in the main, or power supply board related to capacitors.

    Could someone guide me as to where to look to possibly repair the problem?

    Do a factory reset, you will have to redo your settings but it might fix it if that don't work try a firmware update. might not work but it won't cost anything to try and a good place to start.
    Quit because THIS SITE LETS A ROGUE MEMBER TYPE ANY GARBAGE HE PLEASES AND THE POWERS THAT BE NEVER DO ANYTHING ABOUT IT SO HE NEVER QUITS. THEN YOU GET A PENALTY FOR RESPONDING TO HIS ATTACKS. BEEN GOING ON FOR WAY TOO LONG. DONE SUPPORTING A SITE THAT ALLOWS THIS BS.

      From what ive read from sony the Xbr series is also very sensitive to power fluctuations . if you happen to have an uninterruptible power supply connected to your home pc by chance...connect your TV to it and see if the issue goes away.

        Sony Vaio does not turn on, overheats
        by Abel Bejan
        Hello,
        I am quite noob in advanced electronics, however I'm trying to fix a Sony Vaio PCG-71211M laptop mainly because I love old hardware. I don't want to send it to a technician because this computer is not important for me, I want to fix it as a hobby.
        Shortly, this laptop does not display any video output when turned on, no POST, nothing. The keyboard leds are on and I can actually turn Num Locks on and off. Sometimes the laptop turns itself off straight away, sometimes, mostly after some attempts, the laptops enters a loop in which the cpu fan spins very aggressively and the CPU,...

        Sony OLED XR-77A80J - 5 Flashes But Turn On After Hard Reset
        by odie34
        I am a hobbyist (not a professional) so please be gentle...

        I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)

        I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,...

        Sony KD-49XF809y doesn't turn on
        by Zetabeta87
        Hi everyone!
        I have a 2018 Sony kd 49XF8096 that suddenly stopped turning on: No LED lights up, and it doesn't respond to the power button or the remote control.
        The power supply delivers 19.45vand I simply tried to check the fuses on the 2 boards (power and main) but everything seems ok. I have no references on where to test the voltage, but somewhere on the mainboard I also detect some, so you can't to understand which card may be to blame.
        Can anyone give me some advice? I haven't found anything online

        Thanks so much!!!

        Sony XBR-65Z9D won't turn on after lighting strike
        by Highvoltagerchelie
        Good afternoon. I found this forum as I was looking for troubleshooting information for my Sony z9d. A lightning strike hit very close to the house and did nearly $30,000 in electronics damage. The TV appears completely dead with no status light and no picture. I found the Sony XBR-65Z9D service manual and followed the troubleshooting steps on Pages 21-26. All checks seem normal except DC_OFF_DET check on Page 23 R420 voltage was slightly higher than 3V. It was 3.475V and C418 was slightly higher that the 5V at 5.3V.

        I proceeded to check the Power Board CN6401 connector. With all...
