Re: Panasonic CF-54 lan faulty
Can you see the LAN controller in your Device Manager of Windows ? If yes, then the LAN chip is being seen by the motherboard. That is a good start.
Check the RJ45 connector pins that you use for mating the Ethernet cabling. Do any of the pins look bent to you? The connector may need to be replaced.
Otherwise, you will have to open up the laptop to inspect near the LAN connector to check for possible high transient damage that is possible for this port.
A quick fix is to just source a low cost USB Ethernet dongle. If you do this, source a USB 3.0 to Gigabit dongle (Asix or Cypress are good chipsets). -

Windows sees it in the peripheral list and visually disassembling it, everything looks ok even the connector pins. I'd rather fix itComment

I have a Panasonic viera plasma Tx-P50G20B which has a faulty main board. The picture freezes after about 30s and appears to lose vertical hold before finally going black. The main board part number - TNPH0838 (1) A - is common to several Panasonic tvs across a number of ranges however there is a second part number (TXN/A1LTUB for the 50") which is unique to each model.
My question is, given that the TX-P50G20B 50" differs from the TX-P46G20B 46" only in the physical size of the screen, is it possible to use the main board from the TX-P46G20B in a 50"? The secondary... -
Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?
Do you know how to find this connector please ? What is the exact name for find it ?

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
I'm aware pin 3 is ground, but pin 1 is shorted to pin 3 even when not mounted to the machine. It's happening on the original board as well as the ordered replacement board. TV is giving 14 blinks. I'm trying to troubleshoot the machine and thought I'd figured it out when I found a pin that wasn't labeled as ground (Pin 1) shorted to ground, but now I'm just trying to verify if I have two boards with the same fault or if that's how the board is designed and I'm looking in the wrong area.
