Audio will cut in and out, with no picture, If you heat main board with heat gun problem will subside.

The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.
The player processes the audio signal using two different reference frequencies. The "R"... -
Hi All. I had a Roland KR-3500 Digital Piano (similar to the KR-4500) that exhibited a Crackling audio sound on all keys. After reading somewhere about someone with a similar issue who had replaced all the Electrolytic caps I decided to also go down that route. (Spoiler : It worked !) After some basic troubleshooting I determined that it could be noise feeding thru from the Keyboard scanning since the Demo tunes played back undistorted and the Audio amp / speakers were fine ( Inserted an Audio signal into the rear Audio input).

So, laptop was with dead cpu, replaced. Now everything works except i have problems with audio. The problem is related with long audio cable that from one side is plugged in the motherboard and on the other side is connected to audio daughter board that goes on the top of the laptop(behind screen).

1. In bios everything ok (with long audio cable on connector j3701 connected or not),
2. With windows installed everything ok if long audio cable on connector j3701 is not connected,
3. With windows installed and long audio cable on connector j3701 is connected... -
Hi
Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.
Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.
The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.
I have already tried replacing all of the...
