Damaged LCD TV Because of Lightning

[eminem6480]

Guys, 2 days ago nung kasagsagan ng kidlat nadamage yung Sony LCD TV namin. May ilaw ang power indicator pero black out ang LCD panel display. Nag rerespond yung power indicator kapag pinipindot ang remote control (blinking). Out of warranty na po.

Plan namin na dahil sa Sony service center. Just asking:
- usually sa ganitong damage, anong mga parts ang affected?
- any idea sa service charge ng Sony for checkup at repair?
- sa mga nakatry na magparepair ng Sony LCDs, magkano inabot ng total repair price?
- any idea kung may marunong at trusted na repair shop maliban sa authorized service center? Kung sa Raon kaya?

Maraming salamat!

amuyin mo kung amoy sunog yung tv sa likod nya sa mga vents.
Check mo by introducing a signal ( laptop, game console, dvd player etc )
Check mo kung gumagana yung on screen menu
Kung gumaganayung menu problem nyan e backlight.
Nagkaroon ng elec surge yan so most likely psu problem una check,
Now kung may sound e sa av board yan likely yung sync sep ic.
Pero im sure psu yan..gawin mo lahat ng check ng mabilis kasi kung matagal e may madadamay ng part kapag psu problem

have it brought to the sony repair shop po.
raon might be cheaper and they might even be able to fix it, but... hirap punta raon.. masikip.. matrapik.. madaming tao.. malayo paradahan, jeepney stop, or bus stop, sa pintuan ng repair shop.
the sony repair shop near kalaw has parking 2 feet from the door.
whatever problem you may be able to diagnose DIY-style, you will still have to bring it to the fixit shop, unless you are an electronics-repair savvy..
and no... they do not pad repair expenses, as far as i know..
magkano repair fee? natural, depende kung ano ang nasira.. mura lang diagnosis fee.. they will even advise you if it "is not worth repairing"..

we had experience comparing sony repair shop versus ex-sony technician.. hindi nagkakalayo..

Stay away of Raon as surely you'll be in more trouble than having it fix. For one, LCD tvs goes by board level repairs meaning palit board, rather than component level lang. This is how they are gonna take care of pag sa service center. But then, highly qualified techs an gagawa at cgurado kang it will be fixed. Your cheap version will be a trusted neighborhood electronics repair shop who has the ability to diagnose device level on pcb. He should have the right tools though rather than a trial & error method.

YOu can bring it to a Sony Centre near you.

If they can't fix it, they will instead give you an 8K voucher so you can have an 8k discount for your next tv purchase (which of course, is a Sony).

Same thing happened to an aunt, her old Sony LCD TV conked out (screen was damaged, because something was thrown at it). She bought a 40" WB600 internet TV instead. She's almost 80 so she's not really into internet but she just bought it because I recommended it (for her grandchildren).

Guys, wala namang amoy sunog sa likod ng TV. Still no signal nung kinabit ko yung laptop through HDMI, same with Xbox. Blackout talaga ang display and no sound.

We've decided na sa Sony Service Center na dalhin yung unit. PhP600 ang checkup fee. Kung lumabas na yung total repair cost at malapit lang sa brand new baka hindi na namin ituloy ang pagpapagawa.

Maraming salamat guys sa input nyo, I really appreciate it. Thanks!

Bakit nagkakadamage LCD now wala naman ng antenna?

Most likely a power surge caused by lightning instead of hitting the antenna

[dr. d]

in my experience, the more common problem with my sonys is... the power switch!
for some reason, madali siyang masira.. fortunately, madali ring gawin.
sabi nga ng isang tech, lagyan ko na lang ng mechanical toggle switch, at forever fixed na siya.. heh heh.

[jaypee10]

common..

fuses,protector diode or protector capacitors..resistors.

lahat yan sa power supply section ,dun ka muna mag concentrate mag trouble shoot

[eminem6480]

Sad to say, hindi nakakabit sa AVR or surge suppressor yung TV nung kumidlat. Bumili kami ng surge suppressor na Monster Cable HT850 with lifetime warranty. Galing na ako sa service center, ito yung charges:

PhP440 kapag nagpahome service
PhP880 to PhP1100 labor charge depending on tv model and size
PhP600 checkup fee

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.

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.

[nhel0719]

Pero kng gusto ng matipid,1 hibla ng # 22/24 na stranded wire kabit ka ng 1 inch sa aerial antenna

[12vdc]

Separate dapat ang grounding ng aerial antennae. Kung mapapansin nyo ang splitter ng cable TV may provision sa grounding. Telephone box may grounding din. Ang generator sets may provision din for grounding..

Sa commercial power ganun din. From service pole up to entrance cable conduit and panel board may separate grounding.



The idea is to discharge static to nearest earth/ground so lahat ng exposed metal parts/ cable shield ay connected to ground. Fuse, arresters, varisters ay pang clip lang ng overvoltages/ surges and they are useless kung ang takbo ng static ay from line to ground pero walang matakbuhan na nearest ground kaya pumapasok sa loob ng equipment para maghanap ng discharge point.

Dalawa lang drop sa manila di ba? 110 and 110, dito sa province 0 and 220 drop namin. Wala ata kayo service grounding hehehe.. unless other wise yung drop sainyo ay tatlo. And yung outlets nyo ay may grounding sockets.

[joemarski]

^
ganyan nga din po sa probinsiya namin... 220v pero isang cable lang ang may kuryente.
iisa lang kasi 'yung cable na galing sa poste ng electric co. tapos 'yung isang cable naman
eh naka- tap na dun sa "ground rod" na ibinaon sa tabi ng bahay.

ang problema pa doon, kapag daytime, malakas and/or normal ang kuryente.
'pag night time, humihina naman, lumalabo 'yung mga incandescent lamps / bulbs eh.
'yun ngang mga fluorescent lamps, ayaw na ring sumindi.
at 'yung tv naming luma (hindi auto- volt), lumiliit na 'yung screen .

kaya naglagay na lang kami ng AVR para dun sa tv. :thumbup:

[12vdc]

^ Balanced transmission sa metro line1-gnd-line2. Sa probinsya unbalanced line-neutral-gnd not necessarily connected yung neutral sa ground separate parin sila.

Di ba sinabi kung anung board yung sira or part kasi 25k is too much.btw di kailangan 2 3 days para mahanap sira nung tv ngayn kasi may diagnostic tool na mins lang e alam na.di naman nila kailangan signal tracing dahil ang problem ay supply ng tv kaya kamote yung napagdalhan mo especially kapag di nya detail yung sira syo.pa second opinion ka.
