SOURCE: Insignia 26 inch Flat Panel Internal Speakers Stop working

You need to test the unit on a external sound source, to see if the audio amplifier is working correctly. By checking it on another source you can determine if the sound amplifier system is failing or you have had some problem with you speakers. Once you determine the problem. If it is the speakers, you can replace them with new ones. However if it is the audio amplifier section failing you will have to take it to a service center where they have all the service information to do the repairs.If the unit is still under warranty, have it serviced by Insignia. You can reach their customer support with this telephone number !-877-467-4289. Give them the model number of your television and the problems you are having with it. The should be able to tell you how to have it serviced. You can also check out their website for customer support at www.insignia-products.com. If the unit is out of warranty, you must have someone help, you troubleshoot the problem and try buying parts for the repair. You can call this number for insignia parts. 1-888-237-8289. You can also search the Best Buy website for parts on these units. The website is www.bestbuy.com. Go to the parts search section and put in the brand name of you television and put in the model number. The search engine will bring up a parts list with prices.

Zenith B25A76R CRT TV howling sound from speakers


It sounds that there is some solder problems in the audio output section circuit. Loose solder terminals can poise this type of problem. Check it first. Re-solder all the suspected solder terminals by applying a little more solder. If this do not help you, just do as your suspect ion. Replace all the electrolytic capacitors at the audio output section circuit. IC too should be suspected. Check the seating or IC with its heat sink for tightness. If it is loose, the IC will overheat with time, the the fault you report here can occur. Check all of this. Good Luck.

TV Picture reduces to a narrow horizontal bar


The vertical sweep output section circuit to your TV has the fault. Might be an IC failure, or with some loose solder points at the solder terminals to this IC. As it will be very difficult to detect the exact dry-solder point, it will be best to resolder all the suspected solder terminals to this vertical output section, by applying a little more solder to each terminals, without making any solder bridge short in between adjacent solder terminals.

My volume on my Toshiba led 3d tv is very low


Hello
Connect an other speaker, and check. If the external speaker also have low sound output, check the audio output section. Electrolytic capacitors and IC in that section can be suspected.

I have a sharp tv with the volume at its highest but i can't hear anything


Hello
Check its speaker first. If voice coil of the speaker or tis cone paper has damaged, speaker will produce a dull low sound output. If the speaker is found OK, check the audio output section of the unit. This section circuits can be located inside the TV circuit board. look for any loose or bad soldering terminals at the audio output IC. It is best to resolder all the suspected solder points by applying a little more solder, withut making any solder bridge short in between adjecent solder terminals. If this also does not help you, replace the audio output IC. It is damaged. OK.

The speakers are not working. if i turn up the volume, I can hear static noise, but do not get any sound. tv speakers are on. I played around with the audio settinds and all the different hdmi ports,...


Hello
There are two possibilites for this fault. The first one is, damaged speaker voice coil and the second one is damaged audio output IC. To confirm it you have to open your TV. Speakers can be checked without removing them from the cabin fittings. Check them with the helap of a multimeter; set in OHms range. You can alos check it with a standard torch cell also. Connect the two terminals of the torch cell to the two terminals of the speaker [intermittantly, not constantly]; will produce a 'thumb' sound; if the speaker is good.
Connect the 'audio out socket' of the tv, with any other audio equipment, and listen whether there is sound form the external audio equipment, like amplifier or so. If there is sound from the external audio equipment, and no sound from the internal speaker of the TV, and the speaker is good, surely the 'audio output IC' of the TV is damged and should be replaced. OK.

The volume suddenly went out on our tv. you can hear static noise but no talking we havent had it but a few months ..


Hello
Either your TVs speakers or its output IC may have damaged. To confirm it, just up the volume of your tV, and try to hear the sound if any. If it feels like dostorted or very low-hard to hear, the speakers must be suspected. If there is no sound signal at all, output IC should be damaged. To confirm whether the sound detecting section is Ok, just connect your TVs audio output sockets at the rear of your TV with an amplifier or so, and rise the amplifier voluem, to get sound through it. If you get sound in this way, make sure that the above daid two items. Fist check the speaker, by connecting an external speaker in place and listen to it. If it also doesn't get the result, surely the output IC of your TV has damaged, and should be replaced with same type and number. OK.
