    Re: ELEMENT ELEFQ462 led/lcd power problem

    Yes, I would eBay the boards, except the original main board of course. I think you could probably make up the cost. Sucks -- this is the risk of buying faulty TVs! People LIE. And that's really annoying.
    I've only had I think three dodgy TVs (two LCD cracked, one plasma with vertical bar) out of over 50 TVs, though.

        Tom66,
        Thanks again for EVERYTHING! I'll find another project, however, I'll try and be more selective. perhaps look for samsungs or panasonics only.

            Since this TV used a Samsung panel, the exact same thing can happen to a Samsung TV. It's unfortunately a bad design that many LED TVs suffer from.

                Problem with LG Plasma 60PM6700 - Random power downs
                by theone111
                I have an LG Plasma TV 60PM6700 for the past ~12 years.

                In the last ~3-4 months I have been having some issues.
                1. Problem: It started with random picture disappearing (sound still worked).
                  Frequency: Happened about once a week.
                  Solution: Had to turn off TV wait a few seconds before turning it on again.
                2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                  Frequency: Happened about once a week.
                  Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                3. Problem: TV shuts down

                Asus x512dk rev 2.1 power on problem
                by Duranitron
                When I reflash again the bios of hoaca388 the unit powers on and the unit lives!!! Hooray!! All voltage in the coil 3.3v, 5v and 6.7v indicate charging are all present. including the cpu voltage , EEPROM and GPU voltage the unit is now alive, normal screen booting to windows and log in screen until I power it off. Then the unit never goes on even when pressing the power button in the keyboard.. Voltage reading 19v main , 3.3v VCC in IT8225E-128 and EEPROM VCC 0 volt and the charging voltage 0 volt.

                Try to trace the power switch button goin to the power switch IC PU8803 (APL3533AQBI-TRG)...

                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...

                LG OLED55C9PUA power problem
                by EazyBone
                Hello, trying to fix C9 55 inch. I have pulled the back and all looks completely normal with nothing burnt so far. This is first time attempting to fix a tv so any help is appreciated.

                Problem. I hit power button, red light on TV turns off and tries to turn on, no picture shows up and then shuts off. This occurred after house power turned on and off, not from a storm.

                I have tested the power going from power supply to main board, all 12v and 20 volt readings are proper when I hit power button.

                The power supply to t con is different story.
                This...

                Help please..Lenovo ideapad 5 14itl05 power and charging problem
                by Dr.d
                I have a lenovo ideapad 5 14itl05, board LA-K321P, That will only power up on Battery only, or with battery disconnected and power adapter only. If battery is connected and usb-c power plug connected. It only works on battery and will not charge. I can however force it to charge by connecting the battery from a disconnected state while the power USB c plug is powering the laptop.

                Additionally....to add to this strange situation. The usb-c power plug ONLY works to power the laptop on one side when inserted into the boards power usb c plug. If you rotate it 180 degrees, the board gets...
