Some sharp picture would help and be a good starting point for others to offer assistance.

Willing to help but I'm no expert.

Do you have B+ going to the Flyback Transformer?? What about Horiz Osc, is that OK? LV Regulator OK?

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.

Microsoft Surface Pro (5th gen) model 1796 - no power

by PantherDave

Hi all!

I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Asus Probook P5440UF-XB74 power issue

by GLISIT

Hi all,

TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!

I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

Sony Bravia KDL-40V2500 that will not power on

by PopsCaps

I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
I do not hear any sound and I cannot see any backlight.
I have tried disconnecting every cable on each board one at a time to see if anything changes.
The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
My friend ordered another used power supply board but it is also doing the red indicator flash 3 times...

For masochists who want to see some of the crap that I have been through already... (Truly optional now though, all those trees were barked up for no reason.)

I started a new thread to get a fresher look at things, even with eyes that looked before. It's different now!

So I got this on Facebook for $66US, blank screen. Just reseated all...
