this Samsung model HP-T5054 TV WAS GIVING TO ME.WHEN I plug it , there is a clicking coming out of the center board in the back.First i looked at the capacitors they all look good.next i unplugged the Y main board(left side facing from the back)then plugged the power plug in, it still clicks.i did the same with the X main board(right side)powered it up still clicking.when i disconnected the board with the video connections (lower center)and plugged power cord in the clicking went away.still nothing else worked.Help me . thank you.

Re: SAMSUNG HP-T5054 will not turn on,clicks when power is applied to it
Probably a main board fault.
Follow these steps:

(If it still clicks we may need to force power on -- you will need a couple of 100 to 470 ohm resistors to do so.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: SAMSUNG HP-T5054 will not turn on,clicks when power is applied to it
These have power supply issues and not just with the caps on the stand by supply. Those will be bad and not always buldged.
The other problem with these is the two mosfets QX801 and QX802.
On the backside of the board you will need to replace diode (smd) dx803 and dx804.
There is also two resisters, I think they were 100ohm. (two for each diode) also smd.
I think they are in parallel with the diode.
These don`t always go bad but they are easy to check. Normally one will be shorted and some of the resisters will be open.
Hope this helps.Comment

your image 2of4 looks the same as my tv,but my control board looks different,its about 6 inches square pn#WL452DA17AN5J2. also if i disconnect the control board then connect power it still clicks. hope this will helpComment

OK, you will need to get some 100 to 470 ohm resistors.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: SAMSUNG HP-T5054 will not turn on,clicks when power is applied to it
I wasn`t sure what resistors i needed to buy.I bought some 470ohm,do i need other ones to? If so what do i need to get? Thanks again for your help.Comment

Re: SAMSUNG HP-T5054 will not turn on,clicks when power is applied to it
470 ohm is fine -- I meant any value from 100 to 470 ohm.
You will need to measure the voltage on PSON and VSON just as it clicks on and before it clicks off to determine the correct polarity.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

what is PSOS,VSON and where are the points at?Comment

Re: SAMSUNG HP-T5054 will not turn on,clicks when power is applied to it
They are on the connector going from main board to PSU board and should be labelled.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I found the connector,its not labeled,it has 24 pins,its the only one between the boards, which pins are the power pinsComment

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.... -
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 everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
Hi All,
Need help.
I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.
So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard.... -
Hi. First time post. I've scoured the previous forums looking for info - there isn't much for my model
UN65MU8000FXZA
We had a power outage. Everything plugged into the Monster surge protector seems to be fine except my Samsung TV. It was dead when the power came back to the house.
Here's what I've looked at:
Unplugged main board from power supply - BACKLIGHTS COME ON.
Ordered new main board - still didn't work. Not sure if used MB was DOA
MAIN BOARD = BN94-12295K
PSB= BN44-00912 L65E8NR_MHS
There...
