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

by m1ch43lzmHi, 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

by SonicSkyeFirst, I want to thank anyone who has taken the time to look at my post.
I have a Lenovo ideaPad 3 17IIL05. Board ID: GS454/GS554/GV450/GV550/HS750 Rev 1.0 NM-D031. Intel i5 (10th gen) with 4GB onboard SK Hynix modules.- I've found memtest86 v11.5 is showing the onboard RAM is failing.
- I've attempted to use the following schematic to disable the onboard RAM: nm-d031
- I moved resistors RC826 to RC839, RC827 to RC840, and RC828 to RC841.

by howardc64All 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

by frankcapo08Hi everyone,
I need some help diagnosing what seems to be an incomplete board replacement on a Lenovo Legion Pro 7i Gen 10 (16IAX10H).
The laptop works, but some firmware/EC functions are broken, and I suspect the new motherboard is missing /kblt data or has the wrong base record.
RGB lid logo does NOT work in Lenovo Space, but Lid RGB works only in Windows Lighting, not in Space
Also, if anyone here has access to a properly programmed Lenovo Legion Pro 7i Gen 10 (16IAX10H), I would really appreciate if you could share the LVAR variable values for this...4 Photos-
