Question about Zenith C27A24T 27" TV

1 Answer

Speakers have died?

Hi. Hope someone can help. I have a Zenith 27" regular tv about 12 - 15 years old probably. Works great until a couple of days ago. A huge screeching noise started while I was watching something. I changed the menu settings to mono speaker (from stereo) and the screeching stopped. Since then, I have got to turn the sound up a little more and there is a slight static white noise. Is this repairable? Or is it worth it? Thanks. K

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.

Absolutely not worth repair. You have described a classic symptom of Zenith picture tube failure, and about 99% of the time the main board in the TV is ruined as well. You've gotten good life from the set (manufacturers figure tube life is around 7 years these days), so it's time to replace it.

I do not have a Zenith B25A02Z TV. What I do have is a 1988 Zenith Color TV SE2517P. I called a local tv repairman and discussed the problem over the phone. He can take a look at it if we bring it in (service call to the home cost $100 just to show up). He said it was worth fixing since he thought it was only the sound. We have a great picture. He charges $20 to look at it but we have to leave it. He lives 20 minutes away one way. We think it is worth the trip if we can get it loaded into our minivan. We live in western NY where the weather can get pretty ugly many days. I will post the solution later when I know. FYI

I sorry to say I think you have a component failing that is related to heat. 15 years is a long time and if the TV was used in hpot conditions over the years it may well be the proble, or it's just old.

T V sound

great ma ma- first of all if the tv was dropped,then there is a good chance that the pc board was damaged most likely a small crack near the audio section.This sort of repair is probably better left to someone with very good soldering skills. If you think you know someone,let me know I can help. cooltek Feb.15/08

Tvs are wired differently these days. Your old Zenith for example probably had a selector switch that allowed you to change from internal or external speakers, bandpassing the audio from the internal amplifier to the audio out connectors. Your Sharp on the other hand may be controlled by customer menu to perform the same function as the external switch. Go into the menu and sub-menu of the audio and see if it gives you any choices for selecting internal or external speakers... If it doesn't it probably will not bandpass the already amplified signal, which means if you want to listen to your Tv on those external speakers you'll first have to pass the audio sample through an amplifier.
Hope this helps.
