Question about Audio Players & Recorders
There was no problem with your TV, Amplifier and to your HD cable box. This was caused by weak signal chained from your HD cable box to your Harman Kardon reciever and then to your TV. The picture/sound will be fine first then became worst after an operation because the source withdrawing to much current to generate the signal.
You need the HDMI BOOSTER to enhance the the transmission of signal and have a much quality of picture and sound without an interruptions.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

It's definitely not a problem with the cable box or signal strength, but I need a little more information from you to assist me in solving this problem. As you can connect the cable box directly to the TV without any problem, it's more likely to be an HDMI compatibility problem between the TV and the HK receiver. Please could you let me know he following information:
- Brand and model number of TV
- Brand and model number of cable box
- Are there any specific points when the video and audio drops out, e.g. when a channel cuts to a commercial break?
- How long are the dropouts - a second or two or does the signal not return after the dropout?
Personally, I would always connect the cable box directly to the TV anyway and run a digital optical cable from the cable box to the receiver for audio - unless there are specific reasons for connecting the cable box via the receiver, e.g. limited HDMI inputs on the TV.
It could be an HDCP issue, a change in the audio signal type from the cable box, or it's possible there is an unresolvable compatibility issue between the receiver and your specific TV. If you can let me know the answers to the questions above, I can hopefully determine where the problem is or at least make some suggestions which should help.

Hello First tun off the Main Power Switch and unplug the AC power cord for at least 3 minutes. Plug the cord back in and turn the receiver on.

The dropout you describes here is related to its buffer section. There is a section that buffers the HDMI signals, like in our computes. and si composed of ICs. If any one of them wond function well, the 'Buffer Under Run" process will be interupted, and the video will aso effected. The only way to confirm is to reset the processor. The processor reset method is described in its user manual. Anyway I'll give it to you here. Dual 24-bit, twin core Texas Instruments DA 710DSP processors, at 192Khz/24bit Analogue to Digital and Digital to Analogue converter type of processor is used in your system.

until the RESET message appears.
Check after this process. If it helps you, you are lucky. If not, the set should be service by Authorised Herman Cardon service center, because, no user servicable parts in this section, and to service this section, very sophisticated testing equipments must available. These equipments can't afford to alocak serivce technican at all, because of it high cost.
Check this first. If you have some doubt, refer to its user manual too. OK.

Tips for a great answer:

Mar 19, 2013 | Harman Kardon AVR 3600
IMPORTANT NOTE: If the AVR's video output resolution
is set higher than the capabilities of the actual connection,
you will not see a picture. If the best available video connection
from the AVR to the TV is composite video, press this button
and change the resolution to 480i.
