I have a Protron PLTV-26M TV and when I plug the power cord in/flip switch the status indicator comes on orange then goes to red. I push the power button and the light turns green and the screen flashes but then turns completely off, not status light or response of any kind. I have to unplug it to reset it and it will do it again. I looked at the voltages on the board and it looks like I briefly get the right voltages but it is almost like the psu is going into a protection mode...I have tried unplugging the other cables going to the inverters and such but it still acts the same way. Could this be a short on the psu or something causing it to trip itself completely off?

Re: Protron PLTV-26M Power?
What no photo of the PSU or a board number.
Try turning it on with everything connected except the cable to the inverter, what happens now?. -
Re: Protron PLTV-26M Power?
Without inverter plugged in it still acts the same way
FSP180-3M02A is the board numberComment

Re: Protron PLTV-26M Power?
Now try disconnecting the connector from the main board to the t-con, any change?Comment

Re: Protron PLTV-26M Power?
No change...Can I jumper the PS_On to the 5V standby to turn it on and see if the power supply is the problem?Comment

Re: Protron PLTV-26M Power?
Yes, try that. You'll need a resistor.
Have you removed the heatsinks on top to inspect the caps for bulging or leaks?
What voltage do you get across the main filter cap?Last edited by notallbad; 10-17-2013, 11:30 AM.Comment

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... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
