Re: PHILIPS 32PF5420710 not power on
So do you have any DC Voltage on the connector that goes to the main board? All 0V?Never stop learning

Re: PHILIPS 32PF5420710 not power on
My problem is that I do not know what voltages and which wires from the connector that goes to the main board have to carry them.
In other occasions you have the tensions and the name of each cable painting on the board, this time it has nothing and I can not find the scheme of the power supply.Comment

Re: PHILIPS 32PF5420710 not power on
Right now we just need to know if there are any DC Voltages at all at the connector, so please just report what each pin has, that is what I will do if I have the board in front of me.
BTW, sometime they print pin names on the bottom side of the board.Never stop learning

We also need straight shot high res pictures of the whole bottom side of that power supply board so I can trace out the circuits.Never stop learning

Re: PHILIPS 32PF5420710 not power on
Tomorrow I will see some indication from the back and what tensions are between the pins.
There are three photos uploaded in high resolution, are not they good?
I can go up more if the details are not well appreciatedComment

Re: PHILIPS 32PF5420710 not power on
Thanks to the pdf of the source uploaded in this post, I have removed the power source from the tv and I have connected on pin 10 a voltage of 3.3v through a 1k resistor. After that I have measured the voltages in the connector and I have obtained these measures:
Pin 1:24,7v
Pin 2:0v
Pin 3:3,3v
Pin 4:3,3v
Pin 5:0v
Pin 6:0v
Pin 7:0v
Pin 8:11,9v
Pin 9:3,3v
Pin 10:3,1v in+with external source
Pin 11:0v
Pin 12:0v
Well, I think the problem is on the main board. What do you think?Comment

Re: PHILIPS 32PF5420710 not power on
Just wondering if you made any progress with your issues?
I have a Philips 32PF5331/10, but mine appears to have the same power board as yours.
Mine is still working, but from cold, it can take a few times switching the set on/off before it will start up, but it seems to work fine after that.
I haven't had it long enough to test it further, but if you need any info or tests that I can carry out that might help, let me know.Comment

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

by sam_sam_samI 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... -
