@vkumar post some images of the chip that you heated up and where it is located on the board. Since it works after you heat it up it is possible that you have cold solder joints or the chip is a flip chip design which has trouble with the solder bumbs (long story ;-). Most of those will have to be replaced to be permanently repaired. Every now and then the addition of a heatsink may resolve it. All this will depend on where and what this IC is. Use [guide|21499|this guide] to post images so we can see what you see. On select models Onkyo had issue with some transistors overheating and causing the amp to suddenly shut down and/or static noise from speakers. Again, we'll need clarification from you to figure this out.

@vkumar you need to make the component on the image so we can see where you installed the heatsink etc. Check the area outlined by a blue circle in the image. It appears to have some heat issue. Check those components and let us know what you find.[image|1079451]
