The ctc169 was the workhorse of the RCA line being used in over 300 models----sounds like a possible audio output circuit---a lot of parts are no longer available and I would be careful having a shop fix a set this old.

YOU "might" be able to get around this with a surround sound system used with a cable box.

SOURCE: TV will not power on

Sorry, I had the same thing happen to me. The problem is a chip that has blown on the main control board in the unit. The board must be replaced, but I checked and as the service place told you, parts are not available. Looks like it is time for a new TV

SOURCE: RCA TV, model number 32V550T. No picture but sound is fine.

hiya

this sometimes is quite simple to fix as it cud be a dry joint on the circuit board where the tube motor sits.


or it cud be the tube is on its way out, which wud be cheaper to buy a new tv rather than have it fixed

SOURCE: Proscan TV powerup

When TV does not start, and sometimes you hear a clicking noise, that means that the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Tv works but no sound


Hello Jjwpod hi, to find where the trouble is, you need to place ear near speakers, you should hear a humming sound, adjust the volume up or down, the humming sound also goes up or down, this means your amplifier is working, no hum means trouble in amplifier.
summary:
No hum: trouble in amplifier, speaker connection.
Humming, but no audio: problem before amplification, most likely the Sound IF stage.

Volume making humming noise when on


there is a bad ground.
the hum you are hearing is ac getting into the audio.check all the rca plugs on the set are plugged in all the way.do not run them close to a power bar either.
sometimes a second unit with it's own volume is hooked up to the tv and then the tv volume is up too high because the other box is turned down.if there is a unit hooked up,turn it's volume up ,and the volume on the tv down,otherwise the tv will amplify the residual noise.cheers,ed

Proscan 40' 40LC45S has a high pitched hum when it is off. Sound goes away when TV is on.


Same problem here, there is a high-pitched sound in standby. As soon as the light turns blue and the TV is on it's gone. I actually exchanged this TV three times at Best Buy but all the models made the same buzz in standby. I was told that it's normal and in the store you can't hear it since there is too much humming from other TVs around. The power is transformed down to a minimum, just for the remote controls, internal clock etc. and this causes the buzz, like when you dim your lights at home. I hooked it up to a surge-protector for clean power and just switch it off over night. During the day it's hard to hear anyway. - Again, since this is my third (!) Proscan 40' exchange I can definitely say that this is normal for this model. I was just surprised that nobody mentioned the same problem so far on the Best Buy reviews.

Poor sound quality


Hi, I sent an email regarding the issue to OnCorpus (the company who makes ProScan)

This is what I got back:

---------------------------
Thomas,
Follow these steps to correct humming issue:
1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

I can't confirm if this works at this moment since I don't have access to my TV.
