Damaged LCD TV Because of Lightning

[joemarski]

Wala ba kayo gamit na regulator or electrical surge protector?

sir, 'yan po ba 'yung "Automatic Voltage Regulator"?

di ba hindi na po kailangan 'yan kasi "AutoVolt" na ang mga LCD TVs ngayon?

What everybody needs but is usually ignored, is proper grounding (that third prong on most plugs). Unfortunately, this is not a common practice in residential wiring because of the added cost during construction. If they do employ 3-holed receptacles, it may not even have a functional ground.

AVRs, surge suppressors, UPSes, including most appliances that employs a built-in surge suppression circuit, works best only if it can find the path of least resistance to dissipate the electrical surge. This is to say that these surge suppressors will only work if a path to ground exists. Otherwise, extensive damage to sensitive components can occur and may even cause injury to nearby people who may be touching the equipment at the time of the strike.

When I had my home renovated, I insisted that areas where high-valued appliances were situated (ie. main computer, home theater, server closet, water heaters and the whole kitchen for safety) were to have a functional three-hole grounded outlets. Touching a metal sink or faucet while your other hand accidentally touching an ungrounded appliance will oftentimes results to electrocution.

Fyi, another entry point for surge is through the cable TV/internet and telephone/DSL).

ok ba magpakabit ng lightning arrester? will this prevent lightning surge?

It should, as long as it's grounded to earth properly.

sabi sa akin ng electrician is may surge protector/fuse daw sa dulo, and it can protect the whole house na daw.

Lightning arrester is useless without the grounding rod.. Static electricity path is always towards the earth, without the proper path(grounding) static will make its way to the electronics up to the power outlet ir anything near the ground.. The ideal loop of grounding system is 4 to 8 ohms.

Surge protection will depend on how the surge enters the line. Usually its line-ground-neutrAl.all those points of entry must be fused line- to-line and line-to-ground using a varistor or gas discharge fuse.

Automatic Voltage Regulator - yung word na "regulator" means ime-maintain niya yung voltage sa desired level usually 220v.

Autovolt - ibig sabihin kaya or compatible ang isang appliance sa specific range ng voltage, e.g. 100-240V

so kung Autovolt ang TV mo, i.e. 100 to 240V, pero nag power surge above 240V, sabog pa din TV.

Ako AVR tsaka lightning arrestor ang gamit ko nakakabit yun arrestor sa cable wire.

Electro static discharge ang minsan fault since most tv today use sensitive iC which are very sensitive to elec surges unlike solid state devices na mataas ang tolerance against ESD or ES kaya advisable talaga na may proper grounding ang lahat ng devices.avr are not 100 % effective as everyone might think.from time to time nagkakaroon din ng spike yang mga yan.my advice if using an antenna install a ground rod or a lightning arrester.disconnect the aerial antenna from your tv kapag may thunderstorm kasi kahit nakapatay unit mo prone parin na madamage.
