The logo I showed can be found on the PCB's of laptops NP530U3B, NP530U3C, NP540U3B, NP540U3C, etc.
I assume this is a logo of one of the PCB's manufacturers, but I'm not sure.

The logo I showed can be found on the PCB's of laptops NP530U3B, NP530U3C, NP540U3B, NP540U3C, etc.
I assume this is a logo of one of the PCB's manufacturers, but I'm not sure.

Hi Badcaps,
I've had a friend discard a TH-65DX700Z Pansonic Viera Television and I've decided to have a go at repairing it. If possible could I please get some advice in terms of diagnosing the problem so I can purchase the appropriate parts for repair whether it be components, a repair kit or a replacement board. I am happy to post pictures if required.
TV Details:
Model # - TH-65DX700Z
Symptoms:
The television turns on and displays a picture then makes a clicking sound and turns off.
I haven't opened it up yet but...09-04-2024, 02:32 AM -
I have this Dell Latitude 5420 with ST: CMF62F3, board GDF40 LA-K491P REV 3.0 that does not power on, i already searched for some clues about this problem that happens on mine but no BIOS i downloaded and flashed did anything.
Only when the power brick is connected, when pressing the power button an amber light lights up at the front and slight decreases its brightness, the RAM and the CPU seem to heat up if the laptop is left connected but nothing else, other than USB devices getting powered.

Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...Today, 03:14 PM

Hi everyone,
I have a dps-162kp-1 runtka932wjqz powerboard wich has no power at all on the cold side.
I replaced ic7903, r7900, R7902, C7901, d7950.
Checked the diodes around the chip and also the caps.
On the ic pin 5 no voltage, pin7-8= 315V
On the T7901 pin 1-4 no voltage, pin 2-3=315V
Anybody have any idea where to look further?
Any help is welcome

Hello all,
This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...Today, 07:39 AM
