JVC I'Art AV-27F703 Left speaker audio not working

[k24a1]

Hello Badcaps.net!

I have an old-school CRT TV that's a JVC I'Art 27F703 from july of 2002 that I use for my older game systems. It has been working great until I noticed that the left speaker is not working. I have also tried adjusting balance and trying external speakers, and that even had the same issue though the equipment itself passed the sound test! I actually took a closer look inside and some of the capacitors on the audio circuitry portion of the mainboard were starting to leak underneath! They were samsung capacitors and uh, I don't see those ever being touted as reputable.... LMAO.

Is anyone skilled with this specific model of TV and can anyone give me an insight on what's going on? I plan to do a full recap to fix the distortion issues that aren't related to any geometry settings and also to make it operate more reliably, but I'm also asking here because I am curious if something else should be replaced. Yes, I did have all the stereo cables connected and I even checked the user settings. The service menu doesn't have a mention of it either and both speakers look perfectly fine. It appears to be an issue in the audio circuitry itself or in the A/V board.

I have attached the service manual of this TV so you all can look through it. I don't have a lot of time to figure it out and I'd like to get this TV working again as soon as possible.

Thanks in advance!

I forgot to reply to this (I had a painful kidney stone that left me sleepless for several nights) but I've determined the culprit. These I'arts have crappy blue Samsung capacitors that start to leak after a while, and replacing those fixed the audio issue. Mine was used quite a lot before I got it so I knew something was going on with the capacitors. The other capacitors seemed fine though, only the larger blue samsungs had the issue of leaking on the bottom. Luckily, nothing was severely damaged and now that the replacement was done I have stereo sound again!

It was overdue for a recap, electrolytics are not really expected to last more than 10 years, although some can and have lasted for 50 or more years.

Several months later and the TV is still working with good audio! Yeah, I'd personally do a full recap but I'll have to put a lot of money into that, and for now it works perfectly fine.
