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... -
Hi,
I have this very stubborn ASUS mobo on the bench, and I already face the wall with it. It just refuses to POST, although everything seems to be OK.
The situation looks like this:
After connecting the board to the power supply on Nuvoton (SLP_S3#, pin 64), the Low signal (50 ohm resistance) appears immediately. PWRNTN# signal goes through Nuvoton to the chipset (confirmed after removing the chipset). The following conditions are then met for the chipset to generate the SLP_S3# signal:
1. RTC oscillates normally (32.768KHz).

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

Hi everyone,
I am trying to learn electronics repair. I purchased a “faulty for spares/repairs” ASUS X99-PRO/ USB 3.1 motherboard for a very low price from ebay – a good enough price to offset the high probability that the board was completely toast and not realistically repairable.
Initial results:
Board would power-cycle when turned on either with switch on board or shorting pwr pins. Fan would spin for a second or so and a QCODE of 00 would display then it would power off and then do the same thing again over and over. I think maybe 2 times in about 100 attempts...
