Damaged LCD TV Because of Lightning

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

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.

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

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.

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.
