Re: Samsung PN60E550D1FXZA Won't power on
So I'm still playing around with this set. Finally found another Y-main to try and still have the same problem. I have removed the bezel and can see no cracks.
To update I changed PSU, X & Y main boards, Logic board twice, and main control board. No luck yet, VE on either Xmain wont read more than 15-19v as in the previous post's testing.
ERC only shows 3 volts. -44v on Vscan should be -198v
X & Y Buffers connected or not to panel makes no difference in voltage readings, buffers connected or not to mains makes no difference in voltage readings. I don't understand this^
What other fault would cause the logic board led to show a problem when 2 different Y mains are connected to LVDS cable? Maybe the cable itself? I looked it over but did not visually see a problem.Comment

Finally got some direction where to look for problem. drussel figured out it is the 3BR0665JZ controller chip @ U5014 causing the problem.
His thread here https://www.badcaps.net/forum/showth...t=43075&page=2
I put my Y main in freezer and it turned on but with this problem, vertical snow lines each side of screen.
Thinking I may need to reseat the connectors on E and F buffers? Here is a pic.Attached FilesComment

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 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.

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... -
Samsung UE75MU7009TXZG Endless Power Cycle
Hi everyone and thanks in advance for any help I might get here
My Samsung TV is about 4 years old. The exact model number is UE75MU7009TXZG.
About half a year ago I started seeing occasional green frames pop up while watching movies. I mean literally green frames. Not the image turning green, but the entire screen turning green for a split second. This happened maybe once or twice during a 2 hour movie. So no big deal, but clearly something was not quite right.
Since a few days, the TV won't turn... -
Hi All,
First time posting here ... my name is Kevin but my friends call me Journey.
I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again....
