No audio, static

Hi I have an Olivia 532-b12 TV My problem started about a year ago. I would be watching T.V, then the sound would start going staticy, then after awhile you couldn't hear the sound, just static. After awhile the time i would actually get to watch the tv with perfect sound decreased (at first i could watch it for an hour before any problems, and it would take another hour before the sound cut out and static took complete control, later the times shortened)I didnt use the T.V over the summer, and when i started using it again the problem was fixed. Then it all started again a couple months ago. Now, i have no sound period, all i can hear is static, nothing from the shows im watching. Another odd thing is if i plug speakers into the sound output (headphone) jack, i also have the exact same problem.

SOURCE: Sound and Volume trouble

I bought my Insignia 32" LCD in November 2007 - same problem. I figured out that if you press the "input" button on your remote select any of the other options "component 1, composite 1, etc.. that you're TV isn't on -then press "input" again and go back to the component that you're TV plays on - you'll have volume when you go back every time. I've gotten so used to doing it now that it's become habit. 9 times out of 10 I have to do it.

SOURCE: Sound Will Not Come Out of Insignia NSLCD 32

Hi there, the problem you are having lies in a (or maybe 2or 3 )bad capacitors. They are in millions of electronics wreaking havoc on consumers. They will couse symptoms like; no sound, clicking when turning on, power light flashing, suddon shutdowns etc etc...Here is the most detailed explanation on how to diagnose and repair this problem, also have i written down how to (dis) assemble most tv/monitor models. Try this first and if you don't feel like repairing it yourself, at least you would know what to tell the(sharks) repairmen lol..here it goes;.......
The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol!

If this has helped you (or not), please rate, thank you!

Want to connect my thinkpad to the Olevia 532-B12 CD TV. Cables I have found show 15pin conenctors for the video and signle RCA plugs for audio. The back of the TV indicates it needs an audio splitter...


what connections to you have on your computer? because it is best to match connections with tv to computer. s video? hdmi? they sell av or color stream cables with a splitter to connect to computer color stream is just for picture av (RCA input) is for both video and sound.

OLEVIA 532-B12 need video card


The electronics are known to go bad with these TV's, and I'm looking to buy someone's junk TV that has a good screen, rather than have to throw it out.   
(So if anyone is out there with a 532-B12 that isn't working, send me a message!)

If it's a simple replacable part, it might be worth fixing - however I know sadly that parts are nearly impossible to get for these TV's, and the manufacturer is virtually impossible to contact. I think that Sears repair person might be making it sound a little more modular than it really is.  If he's talking about replacing the mainboard of the TV (which IS a video board), that's basically "the guts" of the TV, and not a readily available part like a power cord, back side connectors.
If you DO manage to contact anyone (manufacturer or otherwise) who can source or supply parts, PLEASE do let me know - it's been nearly impossible for me, and I want to replace my cracked screen in my TV.
If you can't, please let me know - I'll gladly give you a few bucks at least to salvage the screen from your TV, to transplant into mine, rather than turning it into junk on your curb.

Suddenly the Tuner mode reports "No Signal"


Just a solution.

I attached a video recorder., and selected the video channel.
I was able then to see the channels through another AV slot extension.
Then I reset the TV to factory settings.
Samsung full HD reset code is 0000.
I used the original remote control.
I pressed the button TV/DTV to switch between mode., and from the menu I started
the option to scan the channels automatically.
Because the VCR was still connected it looks like it was forced to admit the channels.
I turned off the VCR and click on the TV the remote control for a known channel ( alternative control used) and surprise ... The TV started to react according to expected.
I disconnected then physically the cabling from the VCR and plugged in directly on back on the
wall connector. All is ok.
What was the reason ?
My wife dropped the alternative remote control ( not the original one) on the floor, and apparently an strange code was sent to the TV., which suddenly displayed " No signal".
I hope this can work for you.

Kind regards
Sanchez

The electronics are known to go bad with these 532-B12 TV's, and if you have NO picture, that's probably what's gone wrong.  
These are LCD TV's, not plasma, so they don't leak (or, if the crystal layer leaked, you'd see more of a damaged picture, as opposed to NO picture).
I've actually got one of these TV's that I dropped, and cracked the LCD, and that's exactly what happened.   ...In fact, I'm looking for someone who has a TV with a good screen but bad electronics, to buy from them so I can swap the screen into mine, and so they get a couple bucks at least rather than tossing it to the curb... let me know.
I don't think that 1.5 years is long enough for a TV... the TV in my living room is almost 10 years old and working like new still.  Sadly, repair costs might be more than it's worth, especially with all the deals you can find out there right now.  But research it.
Let me know what you decide though, if that TV is truly broken, I will gladly give you a few bucks for it.

Speakers have died?


Probaby the stereo decoder IC went bad or a supply voltage to it is too low or noisy. If it has audio output jacks on the back of the TV, connect it to an external amplifier and see what that sounds like. If it is ok in stereo or mono mode then the amplifier in the TV is bad. This will prove that the stereo decoder is ok.
