I have a p50s30 that will not do anything. You plug power in and get no sound of relay clicking, no lights, no picture. Can someone walk me through how to test this with a volt meter? Thanks!

Re: Panasonic tc-p50s30 no power please advise!
This is either a power supply or mainboard failure.
Measure for 5V on the big connector going to the mainboard.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

Re: Panasonic tc-p50s30 no power please advise!
Which pin(s) should I check? I can't seem to find any voltage at either end of the connector.Comment

Re: Panasonic tc-p50s30 no power please advise!
Can you take clear pictures of the boards? I got this tv in parts , if i remember correctly there is one connector that goes to the mainboard called "P6". It must have 5v on one of the pins. Don't have the schematic.
It's tricky. On the VT50/GT60 a dead tv is a bad mainboard , on this tv im not sure yet. Need a schematic.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Here is a picture. It does have a connector p6 that goes to a6.Attached FilesComment

Re: Panasonic tc-p50s30 no power please advise!
While you wait for moreno have you tried disconnecting sc20 and sc2 cable and if power returns. The sc board commonly fails and goes short across sc2 pins which you could also check. Not sure if it can cause a no standby led it mayComment

Re: Panasonic tc-p50s30 no power please advise!
Ok. I checked that as well still get no relay click or power light. Any ideas?Comment

Re: Panasonic tc-p50s30 no power please advise!
This is from manual for GT30, but i think it should be the same pinout for your tv.Attached FilesComment

Re: Panasonic tc-p50s30 no power please advise!
Yeah I think you'll need to get the manual and see what voltages are present . Could be power board or A boardComment

Re: Panasonic tc-p50s30 no power please advise!
Thanks for the pictures. I got the same powersupply and mainboard but with a different SC board. The PS is also in the 42ST30 / G30 / S30 and U30.
I will measure the voltages on the powersupply alone and with the mainboard connected. Will be tonight though ....i am at work!
But ofcourse you need 5V on the P6 connector going to the mainboard.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Re: Panasonic tc-p50s30 no power please advise!
Thanks so much! I was unable to get any voltage from the p6 connector. Would that indicate a bad ps or a board?
Thanks again for all the help!Comment

Re: Panasonic tc-p50s30 no power please advise!
Well if you don't have any voltage on that connector start checking PS, fuses first

Re: Panasonic tc-p50s30 no power please advise!
Thanks. I checked the 5 fuses and have continuity across each one. I am not sure that I was checking the p6 connector correctly because I wasn't sure which pin should have voltage. I tried grounding one probe to a screw on the frame of the tv and the other probe to each pin, and I did not get power to any pin. Also, on the board there is a printed schematic beside the connector. It shows that several different places should have 15v... Is this A/C or D/C power? Sorry if this is a stupid question.Comment

DC voltsComment

Re: Panasonic tc-p50s30 no power please advise!
Its 5V / 15V DC.
There is a black line on the powersupply that cuts the board in half. One side is AC and the other side is DC. ( high current to low current ).
You sure there is no 5V on P6? You measuring via ground?I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

I will measure it again to make sure. It is possible I was doing it wrong. I will let y'all know. Thanks again for all of the help!!Comment

Re: Panasonic tc-p50s30 no power please advise!
Here are some pictures I took of what I am getting... I am not getting incoming voltage to the ps now. And I swear I was yesterday. Should t I be getting 120v at p9?

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... -
Hi. I have a Panasonic TX-50EX700B which hadn't been used very often for some time. Recently it started getting used a little more often, until one day it just refused to power on with the red LED blinking 13 times. Upon researching, it turned out it apparently had something to do with the 5v power line, so I assumed it was probably the power supply.
I purchased a power supply for the TV from a seller that claims that it works fine and was just taken from a TV with a broken screen. After fitting the new power supply and trying the TV, I was greeted with the power LED being red for...
