    Help for Hitachi 42HDX99

    TV goes through power cycles when turned on. Stays on for 5-10 seconds then turns off for 5-10 seconds. This process is repeated until the tv is unplugged. I replaced two potentially bad caps (very slight bulging) without improvement. Next step?

    The blue light on the front of the TV flashes 8 times. I am having trouble locating a service manual, any suggestions?

    The power supply is shutting down and restarting.

    We need clear pictures of the power board, back and front.

        Your pictures are a bit out of focus and low resolution.

        1) Post clear focused pictures of your boards after reading

        https://www.badcaps.net/forum/showthread.php?t=1868

        2) Please do not post pictures inline as they slow down the loading of pages.

        3) For best picture quality and clarity take your boards to a window on a sunny day, turn flash off, and use macro mode. Take a top down view of all your boards (front and back). Make sure the photo is legible so that we can read the PCB printing clearly. A shutter speed of 1/125 or faster will produce nice clear focused pictures. Try to get a photo that is 2000x2000 resolution or as close as possible.

        If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

        We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

        Please do not post inline and offsite as they slow down the loading of pages.

            For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

            Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

              purplebird05,

              Did you ever find a solution to your 42HDX99 shutting off and coming back on? I have the same TV with the same problem. Please let me know.
