          On the board is a plate to make protection and that also should make dissipation, underneath this plate is 4 ic and there is the error is that the heatsink is detached from the IC. Necklace also sinks on the ic EM6A9320BI-4MG and does not happen anymore the power turns off.

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Assuming...

            by m1ch43lzm
            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
            by ohren
            I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

            I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

            The models launched in 2018 and 2019 respectively....

            Samsung LN46C630K1F – Intermittent Backlight, BN44-00341B Power Board

            Summary for TL-DR readers:
            • Backlight is intermittent, may come on with TV boot or not. No flickering, never fails during TV on.
            • Have obtained Samsung schematic & service documents - Can upload if helpful.
            • Have read ALL applicable threads
            • C1818 and CP820 replaced as low hanging fruit
            • CN802 data taken for normal and failed BL operation. SUMMARY: Pin 2 - 5vDet = 3.52 @normal, 0.0 @BL fail. Pin 6 - EPWM = 1.631 @normal, 1.058 @BL fail.
