Damaged LCD TV Because of Lightning

[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:

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

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

lifetime warranty... does that mean the warranty is over once it breaks down and dies? heh heh. joke.
i recommend dalhin mo na sa shop. mahirap yang sa bahay gagawin..
serviceman arrives.. open up tv.. diagnose and identify part to replace.. go to parts store.. come back with replacement.. wrong part pala.. go back out.. come back.. hassle!!
tekateka... check up fee and labor are different? why naman? how will repairman know what part to replace, if he didn't check it up? andisn't check up part of the labor?
ang tandako.. yung check up fee is credited as part of the labor fee once the transaction is completed..

Sir Dr. D, dinala at iniwan ko na sa service center, 2-3 days daw malalaman yung defective parts na kailangang palitan.

Doon sa Monster Cable HT850, may 5 years warranty sa lahat ng appliances na nakakabit sa surge protector. Monster company will pay for damages or replacement. Lifetime warranty, once the device is damaged, they will replace it with a new one, same model or newer model.

Checkup fee will be charged if hindi namin pinatuloy ang repair.
Hindi ko naitanong pero dapat waived na ang checkup fee at labor cost na lang ang babayaran kapag pinatuloy namin ang pagrepair. Sa Sony Service Center po ito.

[12vdc]

Checkup fee para dun sa tech na nag trace ng cause ng problem.

Labor charge dun sa nag install ng new component at burn-in test ng tv.

Usually switching power supply lang problema nyan. Sa service center tamad tech kaya palit assembly lagi, ganoon na rin sa raon swap board ang ginagawa.

[eminem6480]

May feedback na from Sony Service Center - estimate cost:

labor - PhP800
defect LCD part replacement - PhP25500

Grabe! Mas mahal pa yung part replacement sa brand new 40" smart TV. Most probably we will be buying a new one. For the defective tv, may marerecommend pa ba kayong repair center or or mga electrician outside Sony? Just to double check kung sa LCD talaga ang sira.

Thanks!

[nhel0719]

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.

Ang sabi is LCD screen panel daw ang papalitan. Yun nga ang nakakapagtaka, mas mahal pa yung parts na papalitan compared sa isang buong brand new TV na mas modern pa. Sa Sony Service Center ko na ito pinacheck. Meron silang PhP550 na checkup fee, iparepair man yung unit or hindi, so I'm thinking if dalhin ko pa sa ibang Sony service center. Baka ganun din ang sabihin, masasayang lang ang PhP550. Thanks!

[crazy_boy]

yung TV namin na nasira din ng lightning surge, dinala ko sa ACT banawe for repair nung saturday. may IC chip daw na sira. i gave them a budge of 1,200 to repair. they will try to fix it within the budget daw.

should i decide that it's too expensive to repaid and pull out the unit, they will charge me 500 for diagnosis fee. which i think is reasonable naman since they need to pay the technician also.

may isa pa akong TV na sira due to lightning surge, hindi ko pa pinapaayos. check ko muna kung ok ba sa ACT.

at that price, i'd get a new unit and sell the defective one for scrap or spare parts.
or you can sweep the internet for used TVs.. these usually sell for considerably less than their brand new brothers.

They are essentially discouraging you from having it repaired and to sway you into purchasing a new one. They introduce new models every few months and maintaining the logistics and inventory of parts for older models costs them a lot of money.

When I was a young techie, I was once part of an in-house service team that fixes dot-matrix, laser and line printers. We did them the old-fashioned way... component level repairs. But in rare cases where the PCB becomes practically unusable (ie. corrosion/rat-piss and vermin damage), we would make recommendations to have the whole system board replaced. One particular board costs P13k in late-90's money. And that was just the buy-price from the principal.

But that's hardly the funny part. At that time, the same printer costs P11k, brand new. Yes.. the system board was inexplicably more expensive than the whole damned printer. :D

[baludoy]

you guys think this device will prevent appliance damage due to those potentially destructive power surges?

[12vdc]

No, that is just a power-on-delay which couldn't correct a surge occurring in a fraction of a second. Those pod's are more useful on motorized or lagging power loads.

Electronics are more protected when connected to a ups(with proper grounding).

If you are not buying yet alam ko may trade in promo
they will give you a 8k certificate

Tapos to prevent that from happening again buy a Monster power (power outlet)
retails at 10k kahit kumidlat pa safe na safe ang TV mo

[non-vtec]

Belkin surge protector is a good alternative. Cheaper also.
