Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course.

I just bought a new ThinkPad laptop and I need to connect it to my home network. I have several computers on my network and can see each other in File Explorer and the older ones can communicate with each other (even with the new one) but the ThinkPad can see the other computers but can't communicate with them. I get the (network error 0x80070035 The network path not found). I tried several scenarios that I found on line but none of them worked?? Since the other computers on the network can communicate fine I'm assuming the problem is with the setup of the ThinkPad? All computers are running Windows...

I noted that a number of consumer entertainment devices have the maximum speed marked on the wired network port and considering that there are broadband plans faster than 100 Mbit, the wired network port can be a bottleneck since some routers do not have Gigabit (only 100 Mbit) support for the WAN port let alone the wired network ports.
One other thing: Certain low cost network cables only have two pairs which limits speed to 100 Mbit. -
Hello, I have a SYMSI70 gas heater board, which has issues with its primary side power supply, controlled by TOP247Y chip.
