Actually, it would be better to use it often, so that any flaws will be discovered during the warranty period. Pag-naglapse na ang warranty, then hinay-hinay na...

All LCD had a rated lifetime, iba-iba but something like 50,000 hours. Hindi naman 24/7 naka-bukas ang LCD, so it should last until your next upgrade cycle and then some... Then again, the panel is just one component of the display. So while the crt may last longer, in real world use, the difference would not be much...

i completely agree

better to catch the problem while under warranty or else :'(

been there, done that, make sure your warranty can be realised not just advertised (does it answer your first question)

but of course pray that you never need to use it

they say if its ok on the first year generally it will last its life, kaya dont worry, nothing on earth is sure except death and taxes sabi nga nila

yung samsung sonama 32" ko after a month nagkaron ng dead pixel, pero pinalitan naman kagad ng samsung ng brandnew. So far wala pa naman akong na ecounter na problema.

I have a 17" widescreen Sony MFM-HT75W TV that I've been using almost everyday (for TV, DVD and even as screen for my computer). It'll be 2 years old by July of this year and so far I'm seeing no problem...

Please help us learn more about LCD TVs by giving us more details.

Does the buzzing or hissing come from the speakers?

Sometimes the source is the TV's speakers, sometimes it's from the backlight. In foreign forums, I've encountered discussions about Aquos and Panasonic LCDs buzzing.

barrister its not coming from the speakers

parang grounded na sound pero mahina khit naka standy

Mrk · « **Reply #14 on:** Mar 26, 2007 at 03:52 PM »

barrister kahit nakastandby or naka on tapos mute ko yung tv talaga both may buzzing sound thats so irritating

tried unplugging the plug nawala then nung sinaksak ko nagstandy yung ilaw may buzzing sound nanaman

barrister · « **Reply #15 on:** Mar 26, 2007 at 06:41 PM »

Thanks for the quick reply.

We're sure that it's not the speakers. Buzzing noise is common for Sharp Aquos and Panasonic LCD - the irritating buzz arises when the backlight is reduced, but stops when the backlight is brightest.

In your case, there's a buzz even on standby mode when the backlight is off. It might be static noise from internal wiring or cables connected to the terminals. Or it might be the transformer (I think it's a device that acts as a backlight dimmer) that buzzes even when the backlight is off.

Read a post from a U.K. site:

Sony Bravia KDL-26U2000 Buzzing Problem?
http://www.avforums.com/forums/showthread.php?t=452933

In his case, Sony UK was not much help. You might have to ask for a replacement TV.

Some forums say that a buzzing noise at the back of an LCD panel is normal --- it's just the backlight transformer. The problem is that some transformers are just noisier than others.

ilan yun dead pixel? others kasi have a certain number of dead pixels before they replace it.

rok · « **Reply #17 on:** Mar 27, 2007 at 06:24 PM »

1 lang ang napansin ko pero nun verify ng technician 3 nakita nya, tapos sabi nya pag may deadpixel daw ussually sunod sunod na daw yon diagonally.

jeyps11_c · « **Reply #18 on:** Mar 29, 2007 at 07:33 AM »

How do you "easily" identify deadpixels?
Parang hirap kasi hanapin niyan eh -- you stare at your LCD and watch out for it.
OR there is a software used to check it -- sa mga PDAs kasi may sofware

Saka ano mas maganda gamitin na background black or blu to see deadpixels (kung stare method).

yung sa akin 1 month of use nagkaroon ng dead pixel, model sony bravia klv-32v300a, tinawag ko sa service center, they picked up the unit in my house then pinalitan ng bagong panel, after 1 week of use meron na naman dead pixel, i called sony again and they replaced it with a brand new unit.. then i purchased a 2 year extended warranty just in case a dead pixel shows up again after 1 year.. so far 2 weeks ko na gamit ngayon at ok naman no problems so far, i am using it excessively, i connected my laptop, ps2, dvd so that if ever may sira macocover agad ng warranty at if possible mapalitan uli ng bagong unit hehehe

about the crt being more durable than LCD i have no idea since LCD's are just new unlike CRT which existed decades ago.

i think normal occurence lang yon even from other appliances, my laptop's charger also spark sometimes when i plug it.

i haven't experienced any buzzing sound whatsoever on my sony bravia.

Alfie · « **Reply #22 on:** Dec 04, 2007 at 10:55 AM »

Yes, it's due to it's having an autovolt transformer.

To avoid the spark, plug it to a 110v or utilize an adaptor with a switch when using 220v.

roodhie · « **Reply #23 on:** Dec 04, 2007 at 11:30 AM »

sir ano ba status when you press the power button.. it is in standby mode or power up na sya...kasi yung philips ko naka power up agad di na kailangan ipress yung power sa remote... thx

Not clear about this. When you first plug into the outlet, it will be in standby mode. Then when you press the power button whether on the unit or on remote, mag power on na dapat sya.

1 year and 2months na Bravia 32V ko. Wala pa naman problem.
Mostly for PS3 use.

roodhie · « **Reply #27 on:** Dec 04, 2007 at 12:55 PM »

when you plug into the outlet, and press the power it will standby mode. Then when you press again the power button whether on the unit or on remote, mag power on na dapat sya. right

sa akin when you press the power. nag power on na sya agad.. di na sya dumadaan sa standby mode....in you rphilips lcd?

Ang alam ko mga lcd at plasma TVs nowadays can last 60000 hours. Assuming na we watch tv around 8 hours a day multiplied by 365 = 2920. Then use this to divide 60000 hours, roughly 20.54 years. Not bad for an LCD.

Sa tingin ko naman in about 10 years suppressed na tong technology na to. Conservative pa yung 10 years. Newer models are saying na LCD can last up to 100000 or was it plasma

Malamang if there are any LCDs na nasiraan dyan mga minor defects lang yun kaya recommendation ko bibili ka lang ng TV invest mo na hard earned money mo sa branded with good warranty service and reputation.

pero ako intay ko pa 13th month saka pa ako bibili ng LCD or PV70?
