RCA F36685 No audio on cable channels

Depending on the age of the TV, I have found that the RCA sockets on TV's will NOT produce an audio out signal. Since they were not designed to do so.
If the TV has an HDMI then that can be converted to produce the left and right channels. But if it has not got an HDMI, it should have and SCART socket, which will also produce the left and right channels.

Why do you need to use RCA cables as a TV will produce sound through the internal speakers without any cables required.

Hi, in most of these RCA TV, we found a common problem with that strange sound.
You need electronics skills to solve this problem. The sound coming from the TV ( back cover), caused by a faulty transformer T14401 location number, part number 241319, also a transistor horizontal output is shorted need be replaced. location Q14401 part number, part number 237470. This is a difficult and you may have to find a tv shop and ask for a previous estimate of money. I hope all this clear in my explanation and if you have further questions, I'll be here to help.

try fine tuning channel 3

check the scart cable/adaptor

I have sound on video 2, and when on a static channel but not on the usual channel 3 which is TV. Just stoppen working one day and cant figure it out... Please help!

No sound and a digital picture. i will assume you have no signal on analog rf cable. Thomson(RCA) have been having problem with these sets. The trouble stems from the digital cuircit board. We see alot of these. You used to get the digital board.. they are not availble.. so rca found the component on these that fail.. A VERY SMALL surface mounted fuse. With a lighted magnifer and some fine tip twezzers. we replace these fuses on these boards. Do you have any soldering experence..

YX2 = part # 244247..................................................T.

Sometims several capacitors start going bad giving you the audio problem, but I don't remember the set turning itself off. That could be a secondary problem around the flyback transformer which may have a bad solder connection. I would check that first. Otherwise, I would be tempted to go with HDTV.
