    Samsung un40h5003 turns on when plugging it in

    I have a weird one. My in laws gave me a un40h5003 Samsung LCD TV that turns itself on when you plug it in and neither the power button on the TV nor the remote do anything, but other buttons do.

    Simple issue I figured, so I opened up the back, and unplugged the power button on the TV from the cable. Retested and it still turns itself on automatically. I pulled the batteries out of the remote and even had the remote in another room and same thing.

    Any ideas why this would be happening? No obvious capacitor issues, no bulging, no issues on either power or main board just from looking at things.

    Based on other threads about similar issues, it would appear the eeprom is corrupted. I ordered a new main board for this unit, only $20.00 after tax and shipping, and will see if that fixes the issue.

            Samsung UE55F8000SZ Turns on and off immediately
            by Egidio85
            good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
            This defect happens continuously, hearing the classic click of the relay every time.

            Power supply board BN44-00636B

            disconnecting the mains and lamps from the power board always causes the same problem.
            Is it normal that without anything connected this power supply turns on and off cyclically?
            any suggestions on what to check?

            thanks in advance

            Samsung B2030HD IR Remote Receiver Dead, shorted micom?
            by jesterace
            Hi,
            I have this TV a small 20 inch that works perfectly except for the IR has stopped. I have confirmed that the remote control is fine and tried an alternative and even tried with IR blaster from phone. Remote 100% ok.

            Tried installing latest firmware but no change.

            TV won't respond to remote at all, not even to bring it out of standby. I have to use the touch sensitive front panel to operate, at which point TV is usable albeit with no remote.

            Tried replacing the IR receiver diode/bulb on front panel and no change so put the old one back. After tracing...
