the jist of it is to look for components which dont work somewhat like they should.
nothing should have 0 ohms to ground (the trace where the screws attach). Probe around and see if you can something that does. Most likely it will be one of those components with a heatsink that shorts to ground.
then you have to look to see whats broken in that area that goes to ground. then it gets harder especially if you dont know electronics and it feels like you are just looking at random objects. going from finding the bad part to fixing it isnt trivial but doable. -

^^ This board is a spare and don't mind to spend some time chasing the bad component, However nothing out of the ordinary ( blown , burn, cracked ) In fact the voltage at the test point AKA VSCAN with dead on but once i replaced the board baam i have 100% functional set.Last edited by R1racer; 12-21-2015, 07:49 AM.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?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.

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... -
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.... -
