    The way I remove the chip like that is to cut the legs, then use 40 Watts Iron and heat up the big tab while adding more solder to it, the melted solder will help keep maintaining the heat, then you just twist the body to get it off the board.

                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...

                HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
                by ttmi100x
                Greetings everyone,


                I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


                The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
                Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

                Upon closer inspection...

                LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                by Hakuu
                Hi There,

                This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                More Details

                TV Model - LG OLED77G1PUA

                Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

                Sony xbr-65x900c main board issues?
                by jb_Bak
                Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                Power Board Connector that goes to Main board
                CN6401
                Pin 01 NC
                Pin 02 NC
                Pin 03 "BL_ON": 0V
                Pin 04 "N/C"
                Pin 05 "STBY 3.3V": 3.5V
                Pin 06 "GND": N/C
                Pin 07 "AC_OFF"...
