if you lookup towards PH and PD connectors in slot L10 these are what I seeAttached FilesComment

Re: NEC Px42VM3A lost all display
They are inductors not fuses, should test shorted.
What about that white ceramic resistor, how does it test & what does it say? Hard to see with focus, remember I do not have this board in front of me.
I have only worked on a 50" NEC chassis and it was reasonably modern, PSU made by Hitachi, main board by NEC & rest of plasma screen made by Pioneer (ex-NEC manufacturing.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: NEC Px42VM3A lost all display
Does it test at 47 ohm or nearabouts.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I am greatful for the help. I know it is difficult when you don't have the PSU in front of you.Comment

Re: NEC Px42VM3A lost all display
the 4 white resistors that show G5W 4.7 ohm Micro 1DT are reading only 3.6
these are up by the 1500uf 200V capComment

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... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi all!
This is my first post and also one of my first "deep dives" into electronic repair. I'm used to doing basic tasks with computers, like SSD/CPU replacement, thermal past re-application, etc. So here's the story...
I have a MacBook Air M1 that I bought to repair (I know, I'm weird; though I'm a CompSci major and want to learn more
, and it will not display anything on the internal display. I have verified that there's no backlight, as I booted the laptop and shined a flashlight on it and there's no display; it does completely boot up, and shows fine on an external...

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.
