HK AVR 7200 Remote Completely Dead

post #1 of 5
Thread Starter 
I went to use the subject remote (actually had it stored in its package with batteries removed) which had not been used in probably more than a year and. I installed brand new batteries in it and there were absolutely no signs of life. I went through a "reset" procedure of pressing every button on the remote for 3 seconds in turn with the batteries and then replaced the batteries and still nothing.

I then took the remote apart and although I saw no signs of contamination inside it, I cleaned each contact point and the control button backs with Isopropyl Alcohol and put the remote back together with no success. The battery contacts were clean and all looked secure and there was a piece of what appeared to be insulating tape on the back of the circuit board where the battery contacts that are attached to the back of the remote could rub on the circuit board which looked to be intact as well.

I could see no signs of cracking in the circuit board or burn spots on the board or components mounted on it. Has anyone else experienced this type of issue with a hardly used AVR 7200 remote control? The online replacement remote control places don't show it available (except for possibly one), but they do show that the DPR 1001 remote is a replacement for it. Visually it appears to be the same other than the name on the remote saying "DPR 1001" instead of "AVR 7200". Prices seem to range from $130-$200. I just missed an opportunity to buy an entire AVR 7200 and remote on Craigslist in my area for $250 a couple of weeks ago.

I don't know if it would be worth trying to take my remote into a local HK authorized repair center or not. I've taken things to them in the past, but the last time I called them they said they had gotten very selective on what HK items they would now attempt to repair because it was difficult getting parts from HK.

Any assistance is greatly appreciated.

Best Regard,

Ted

The question is - remote or IR receiver on the unit. If the remote a cheap universal replacement remote will do the trick. If the IR receiver in the unit, well then your problems are bigger. You did try new batteries, right?

It is definitely the remote, and yes brand new batteries were installed when I took it out of storage. The remote has an LCD display built into it which is inactive. It also has a light button to back light the buttons on the remote and this does not work either. I also pointed the remote at a video camera which would normally "see" the IR emitter signals that cannot be seen with the naked eye and it saw nothing. It is definitely the remote.

Finding a universal remote that will replace it is difficult. I do have a Harmony One that can control some functions, however, there are certain functions that are unavailable even with it.

Double check that both batteries are inserted in the correct direction.

We do know 55 IR signals for the AVR 8000, and I believe these will also work with the AVR 7200. So it is practical to use a universal, although names like "Neo 6" won't be on hard buttons. A RCA RCRP05B (or a cable company Atlas) can be manually programmed with the following 5 digit EFCs, or these code can be converted to Pronto Hex, and loaded into e.g. a Harmony. Signals are NEC1 128.112 or 130.114. Warning: Spoiler! (Click to show)

The batteries are definitely installed correctly. The correct positions are clearly labeled in the battery bay for 4 AAA batteries.
