Lightning strike Our computer that was the secondary one can't connect to the internet without causing the phoneline to be busy when it never has done that before. The computer sparked one night during a storm and the phone tech said it was the phone jack so we moved the computer to another room, bit it still doed the samething. Is it the phone jacks or the usb port that is doing it?

When and How Should a Surge Protector Be Used on a Fixed Switch?


Common Causes of Lightning Strikes
  • Outdoor network cables or power cables are routed overhead.
  • A switch is deployed outdoors but is not properly grounded.

Damages of Lightning Strikes
  • If power cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn the power supplies.
  • If network cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn interfaces of the switch.
When a switch undergoes lightning strikes, overvoltage is induced by lightning on network cables and transmitted to interior of the chassis. The surge protection measures, such as lightning rod and chassis grounding cannot prevent the damage. Therefore, surge protectors or surge protection circuits are recommended.

Surge Protector Use Precautions Take the following precautions to protect a switch from lightning:
  • Ensure that the ground cable is connected to a ground bar or a ground point on the cabinet.
  • Avoid routing cables overhead in an outdoor environment. Bury cables underground or route them in steel tubes.
  • To protect network interfaces against lightning, use 8-line surge protectors (or Huawei certified 4-line surge protectors).
  • When installing a network interface surge protector, connect the IN end to terminals and the OUT end to network interfaces of the switch.
If a fixed switch is installed in a network box, follow these instructions:
  • Connect the ground cables of the switch and surge protectors to the ground bar in the network box.
  • The maximum length of a ground cable cannot exceed 40 cm, and a length of smaller than 15 cm is recommended.
  • If the network box is located outdoors and power cables are routed aerially over a long distance (more than 300 m) to the network box, it is recommended that you install a power supply surge protector in the network box. The decoupled power cable must be at least 3 m long

How check pcb after lightning strikes??


Over voltages as little as 20% greater than expected (under the right circumstances) can cause components to fail with no outward indication of failure. Other times, these same or greater voltages will obliterate a component and without the benefit of a schematic will make identifying & replacing it impossible.

Nearby lightning strikes often cause multiple components on different PCB to fail at the same time, complicating troubleshooting significantly. Faults can appear on power supply PCBs and in the RF stages along antenna / cable inputs and out to cable boxes DVD players, etc.

These are usually not fixed by DIYers without specialized test equipment and manufacturer's service manuals.

Which components do I need to check following a voltage surge (lightning) on Hitachi colour TV CL32WF810AN.


If the main fuse should blow up; surely there should be a short circuit to any component/s at it. If the secondary [DC] fuse also has blown up, there should be a reason for it too.
You should first check out the main power board alone, and then the secondary board connected. It will be impossible to follow these without its schematic diagram. Try to download it by internet. Without proper guidance; how can we follow the complicated circuits, and check the components?
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Will a nearby lightning strike cause a power board failure?


It could happen yes it would depend where the strike entered the TV. Not all lighting strikes hit on the electrical lines, on a TV they can come through the cable, as well as a antenna if you have one hooked up.

We took a lightning strike and my RCA 20f510td has no indication of power. Is there a fuse that needs to be replaced?


Hello
The faults occurs during lightning strike is not predictable. At present, the power supply inverter section of your RCA ahs damaged. A thorough chekup must be done to detect whether there is any other faults also occured or not during this time. OK.

My connection through my 2wire pc port phoneline is extremely slow, the internet is very laggy, yet all the computers connected directly to the router through ethernet cables are very fast


This is because the adapter is ONLY 10Mbps you need a higher one 100Mbps or even 1000Mbps... That adapter is too old to be used on a high speed network, replace it with a faster one.

Lightning


Hi,

In a nutshell, yes and not only to a Dell but to most computer brands/models. In some instances, it's only the modem, router, LAN card that gets fried while some gets everything toasted.

Incidentally, even a near lightning strike is enough to cause big problems.

Kind regards.

Lightning Strike?


Assuming this line is across the screen horizontally (side to side), this means the vertical deflection circuitry is dead. In late model sets, there is a Integrated circuit package which drives the vertical yoke coils. Possible defects: the I.C. itself, bad solder connections where it solders to the board, missing voltage source to this I.C. (often around +24 volts), or a bad electrolytic capacitor in the associated circuitry. This latter often results in a non-linear picture, or less than full deflection condition, rather than a thin line only. It is possible lightning caused this problem, (I've seen some rather illogical damage from lightning ) perhaps it produced enough of a surge to pop the I.C. or a fusible resistor in that voltage source noted above.

Does not power on. Q951 charred


you can look for the model and brand, look for it on the internet and see if you can have the schematic diagram, you're lucky if u can. Lightning will strike first the tuner side, if there is a red blink, the primary side may be okay in switching type regulator, just replacing the charred part may not solve the problem. look for shorted components on the secondary of the power section.
