LCD TV cannot receive sound

[coiter]

hello mga audio/video gurus!

i got an 8" lcd tv with tuner from abroad. it receives local vhf signals (though medyo malabo at chan 7 lang malinaw) but it can only get the video. di nya makuha ang audio. static lang. i've tried changing the audio settings na nasa manual (something like 6.0, 5.5, 6.5, etc) pero wala pa rin. pano kaya maayos to? may paraan ba na pwedeng mabago yung frequency nya to receive local channels' audio?

TIA

[av8or5]

just check the settings on your a/v unit. i had the same problem when i had my installed in banawe, i just played with all the settings and not only the audio setting, but more on the tv tuner settings. my problem before was no reception, afterwards i got reception but no audio, then after that audio but no reception or the color sucks. but all will be fine as long as you check the settings. as in all the settings.

hope maging okay. i dont have my a/v manual with me, its in the car, so I dont know exactly which setting it should be.

[coiter]

I see. thanks. sige, try ko uli kalikutin lahat. hopefully maayos. although pinatingin na namin sa 2 electronics shop and suggestion nila is dalhin sa quiapo or gh para ma-hack sya.

[AC]

sir.. i have the same problem.. from abroad din po lcd ko..

let me know po ha sir.. pano mo nasolve problem mo.

maganda naman reception.. malinaw.. but walang boses..

[russpogi]

Di kaya the audio is routed via FM? Ganun kse yung sa TV ng bro ko sa car nya eh.

[batang_raon14]

Pa-update na rin ako. Same problem with my TV. Malinaw yung reception pero walang audio. Sabi ng electrician posibleng sa cable daw ng antenna 'to, refuse to believe it though.

What country did you bought your gear?

If you bought your gear in U.S you dont have any problem since we are using the same T.V standard NTSC (National Television system committee). Most european T.V are using PAL and thier difference is in audio carrier 6.0 for PAL-I and 5.5 for PAL-B.

* coiter:
You have said that audio setting in your LCD are 5.5, 6.0 meaning they are only works on PAL(Phase Alternating Line) with the differences the audio carrier frequency and channel bandwith in the Philippines since they using NTSC. Find a good T.V technician maybe he can adjusted on it since there are plenty audio converters available maybe around 1 hundred pesos(well, not really sure the price, Im just want to make you feel comportable this problem of yours) and channel problem is even less significant.

Next time buying a gear visit this site on which country should avoid buying stuff that will not work in Phils.

v6dreamer,

dubai ko pinabili. yun din sabi ng mga nakausap kong technician. wag na raw magpabili sa ibang bansa. natempt lang ako kasi sobrang mura dun. sa ngayon monitor na lang sya for dvd player.

batang_raon14 and AC,

so far wala pa kong solution. yun nga, naging monitor na lang talaga sya. sayang. pero may mga nakita ako sa gh na mga tv signal recievers. try kong itest dun.


anyway, ang nakakaasar, kahit sa cable tv ayaw. may picture din pero walang sound. ibig sabihin ba nito e may frequency din ang cable tv? kakainis lang talaga. sayang pera. hehe

[v6dreamer]

Even in cable it wouldnt make no difference. Phils. is NTSC and your system is PAL-B and G (Saudi Arabia), that built-in receiver is for one variant wont receive the sound of the others.

Kung may kakilala kang taga malaysia ibinta mo na dahil pwede sa kanila yan.

Di kaya the audio is routed via FM? Ganun kse yung sa TV ng bro ko sa car nya eh.

so pano ang ginawa niya bro? feeing ko ganon din yung sakin kasi sometimes radio ang nadidinig ko when i try to fix the t.v. thanks..

[av8or5]

i experienced that also. but with the settings that i played with, okay na. see you friday, lets play around with your a/v settings.

coiter,

why not buy the TV tuner na pang monitor from CDR-King... it is quite cheap P2380?

So yung LCD TV has built-in speakers (where you hear the static)? Anyway, looks like V6 is spot on. That's why it's important to have a multi-system a/v gear. Kung hindi auto-switching ng signal, at least meron dapat manual switch to toggle between NTSC and PAL.

This is what you guys needs.

1. Tape conversion: You can exchange tapes with friends or relatives living abroad, or for business and education. PAL or NTSC (depends on the country you are in) VCR is required to do this. ( Note: if you have a Pal or NTSC tape then you have to have a VCR that is able to play that tape as well as a converter, you will not be able to play Pal tape in the NTSC VCR and so as you will not be able to play NTSC tape in a Pal VCR ). Make sure that you get an appropriate VCR when purchasing a converter.

4. Camcorders: Use your PAL camcorder in the USA or your NTSC camcorder overseas on a PAL TV. You can also convert movies from your camcorder. For example: Make a NTSC tape from a PAL camcorder using the SB-3690 to convert the signal.
5. Computer: Use SB-3960 to connect your computer to standard TV or Projector, for gaming or presentation purposes. Also you would be able to view any of your home video equipment on computer monitor.

Why our converter is more expensive then $30 analog converters?
Analog converters can only work with only one Pal or NTSC standard and there is over 14 Pal formats and 2 NTSC formats. Also, analog converter will require a TV to have a vertical hold function, where most TV's no longer have it. Analog converters in most of the cases will not convert Frequency 50/60Hz and therefore will not work with many TV's.



Atlona SB-3690 is a digital converter, which means that it will handle any Pal or Secam or NTSC formats, convert frequency, real time conversion, no signal delay, will not require TV to have a vertical hold or any other special features. SB-3690 is guaranteed to work for all TV's and with all types of equipment. Excellent features list:

• No video delay. Real Time video Conversion.
• Use your PAL/SECAM equipment in a NTSC country and NTSC equipment in a PAL country
• Very easy to use, one time set-up no addition action needed.
• Uses a standard AV or S-Video or VGA connection to convert any input signal to any specified output source.
• Recording in permitted from any of the outputs. You can take advantage of making copies out of devices which are plugged in. Most of the DVD movies and VHS tapes.

• Built-in Color Bar ( for the best image reproduction )
• 2mb field memory. ( Please don't think that 12mb or 15mb converters will give you better image, as we tested our competitors converters and there is only 2mb used. Chip-set which is used on those converters is not able to support more memory anyway. It is just a marketing strategy )

Audio: Audio signal needs to be send on the separate audio cables to the display or recording source. There would be no audio delay.

Medyo hassle pa ito. The converter is $160 (~P7,200), plus shipping, plus inverter (12VDC - 110/220VAC), easily mga P10k na ang gastos.

Benta na lang yung LCD as monitor, plus yung existing headunit, and puwede na mag-purchase nung mga 2-din China-brand do-it-all headunits. Meron na built in DVD player, a wide array of A/V formats, USB, TV tuner, touch screen, iPod interface, etc. Mga P16k lang ito ngayon. Baka may sukli pa for speaker upgrade.

Just my 2¢.

[batang_raon14]

Hehe... solved mine by looking for this in my HU:



I selected USA1 and VOILA! I now have audio in my unit. Hehe... it's not as good as my previous though kasi yung old one ko kahit naandar malinaw parin audio eh, ngayon pag umandar ako medyo intermittent siya. Pero so far so good. Eto siguro yung frequency range na sinasabi ni V6 sa previous posts.

As per russpogi's suggestion naman, yup some TV Tuners (especially NECVOX ones) tap the signal to the FM through signal modulator. It works well but using this method does not affect audio IMO. BUT, it definitely affects AM reception.

batang raon san mo nabili hu mo? pareho ata tayo ng unit eh. ok ba yung t.v. tuner mo? yung sa akin kasi hindi ko mapagana... badtrip nga eh..

[batang_raon14]

I bought mine in Hong Kong when I went there for a conference. Ok naman siya. Yung worst na nabili ko eh yung galing sa eBay. Sira yung backup camera signal tapos sub-standard pa yung quality ng mga pre-outs.

Pano bang ayaw gumana? Ayaw gumana in a sense na blue lang ang screen or something else? Kasi kung wala talagang reception (as in blue lang talaga kahit saan mo pa dalhin yung sasakyan para sumagap ng signal), there's a possibility na either sira yung antenna mo or yung modulator mo (ung type na sa FM antenna nirerekta para magkasignal) or yung saksakan ng antenna sa HU mo (which more or less is either an RCA female plug or a baby plug). Kung meron namang nalabas na video gaya ng case namin ng TS, pwede mong i-try yung kinalikot ko ring option sa HU. Kung meron kang ganun maybe it can do the trick. HTH



MODS: Sorry uli double post yung last one. Nakakabanas na 'tong Smart Bro...

[bluemica]

nung una may nalabas na picture pero walang sound. after a while tinigilan ko na lang din. nung nakalikot ko siya nung isang araw may nalabas naman kaso talagang hindi siya natunog. ano ba gamit mo na system? NTSC MN? meron nga yang audio button pag nandon ka sa tv kaso pag pinipindot ko wala naman nangyayari.. hassle nga, baka sira talaga..
